+# Contributing to Dogecoin Core
+
+Dogecoin Core is open source software, and we would welcome contributions
+which improve the state of the software. For those wanting to discuss changes,
+or look for work that needs doing, please see:
+
+* [Help requests](https://github.com/dogecoin/dogecoin/labels/help%20wanted)
+* [Projects](https://github.com/dogecoin/dogecoin/projects)
+* [Dogecoindev on reddit](https://www.reddit.com/r/dogecoindev/)
+
+## Branch Strategy
+
+Dogecoin Core's default branch is intentionally a stable release, so that anyone
+downloading the code and compiling it gets a stable release. Active development
+occurs on branches named after the version they are targeting, for example the
+1.14.4 branch is named `1.14.4-dev`. When raising PRs, please raise against the
+relevant development branch and **not** against the `master` branch.
+
+## Contributor Workflow
+
+The codebase is maintained using the "contributor workflow" where everyone
+without exception contributes patch proposals using "pull requests". This
+facilitates social contribution, easy testing and peer review.
+
+To contribute a patch, the workflow is as follows:
+
+  - Fork the repository in GitHub, and clone it your development machine.
+  - Create a topic branch from the relevant development branch.
+  - Commit changes to the branch.
+  - Test your changes, which **must** include the unit and RPC tests passing.
+  - Push topic branch to your copy of the repository.
+  - Raise a Pull Request via GitHub.
+
+The coding conventions in the [developer notes](doc/developer-notes.md) must be
+adhered to.
+
+In general [commits should be atomic](https://en.wikipedia.org/wiki/Atomic_commit#Atomic_commit_convention)
+and diffs should be easy to read. For this reason do not mix any formatting
+fixes or code moves with actual code changes.
+
+Commit messages should be verbose by default consisting of a short subject line
+(50 chars max), a blank line and detailed explanatory text as separate
+paragraph(s); unless the title alone is self-explanatory (like "Corrected typo
+in init.cpp") then a single title line is sufficient. Commit messages should be
+helpful to people reading your code in the future, so explain the reasoning for
+your decisions. Further explanation [here](http://chris.beams.io/posts/git-commit/).
+
+Please refer to the [Git manual](https://git-scm.com/doc) for more information
+about Git.
+
+The body of the pull request should contain enough description about what the
+patch does together with any justification/reasoning. You should include
+references to any discussions (for example other tickets or mailing list
+discussions). At this stage one should expect comments and review from other
+contributors. You can add more commits to your pull request by committing them
+locally and pushing to your fork until you have satisfied feedback.
+
+
+## Squashing Commits
+
+If your pull request is accepted for merging, you may be asked by a maintainer
+to squash and or [rebase](https://git-scm.com/docs/git-rebase) your commits
+before it will be merged. The basic squashing workflow is shown below.
+
+    git checkout your_branch_name
+    git rebase -i HEAD~n
+    # n is normally the number of commits in the pull
+    # set commits from 'pick' to 'squash', save and quit
+    # on the next screen, edit/refine commit messages
+    # save and quit
+    git push -f # (force push to GitHub)
+
+If you have problems with squashing (or other workflows with `git`), you can
+alternatively enable "Allow edits from maintainers" in the right GitHub
+sidebar and ask for help in the pull request.
+
+Please refrain from creating several pull requests for the same change.
+Use the pull request that is already open (or was created earlier) to amend
+changes. This preserves the discussion and review that happened earlier for
+the respective change set.
+
+The length of time required for peer review is unpredictable and will vary
+between pull requests.
+
+
+## Pull Request Philosophy
+
+Pull Requests should always be focused. For example, a pull request could add a
+feature, fix a bug, or refactor code; but not a mixture. Please avoid submitting
+pull requests that attempt to do too much, are overly large, or overly complex
+as this makes review difficult.
+
+
+### Features
+
+When adding a new feature, thought must be given to the long term technical debt
+and maintenance that feature may require after inclusion. Before proposing a new
+feature that will require maintenance, please consider if you are willing to
+maintain it (including bug fixing). If features get orphaned with no maintainer
+in the future, they may be removed.
+
+
+### Refactoring
+
+Dogecoin Core is a direct fork of Bitcoin Core and therefore benefits from as
+little refactoring as possible on code that is created upstream. If you see any
+structural issues with upstream code, please propose these fixes for
+[bitcoin/bitcoin](https://github.com/bitcoin/bitcoin) and future Dogecoin Core
+releases will automatically benefit from these.
+
+When refactoring Dogecoin-specific code, please keep refactoring requests short,
+low complexity and easy to verify.
+
+
+## "Decision Making" Process
+
+The following applies to code changes to Dogecoin Core, and is not to be
+confused with overall Dogecoin Network Protocol consensus changes. All consensus
+changes **must** be ratified by miners; a proposal to implement protocol changes
+does not guarantee activation on the mainnet, not even when a binary gets
+released by maintainers.
+
+Whether a pull request is merged into Dogecoin Core rests with the repository
+maintainers.
+
+Maintainers will take into consideration if a patch is in line with the general
+principles of Dogecoin; meets the minimum standards for inclusion; and will
+take into account the consensus among frequent contributors.
+
+In general, all pull requests must:
+
+  - have a clear use case, fix a demonstrable bug or serve the greater good of
+    Dogecoin;
+  - be peer reviewed;
+  - have unit tests and functional tests;
+  - follow code style guidelines;
+  - not break the existing test suite;
+  - where bugs are fixed, where possible, there should be unit tests
+    demonstrating the bug and also proving the fix. This helps prevent
+    regressions.
+
+The following patch types are expected to have significant discussion before
+approval and merge:
+
+- Consensus rule changes (through softfork or otherwise)
+- Policy changes
+
+While each case will be different, one should be prepared to expend more time
+and effort than for other kinds of patches because of increased peer review
+and consensus building requirements.
+
+
+### Peer Review
+
+Anyone may participate in peer review which is expressed by comments in the pull
+request. Typically, reviewers will review the code for obvious errors, as well as
+test out the patch set and opine on the technical merits of the patch.
+Repository maintainers take into account the peer review when determining if
+there is consensus to merge a pull request.
+
+Maintainers reserve the right to weigh the opinions of peer reviewers
+using common sense judgement and also may weight based on meritocracy: Those
+that have demonstrated a deeper commitment and understanding towards Dogecoin
+(over time) or have clear domain expertise may naturally have more weight, as
+one would expect in all walks of life.
+
+Where a patch set proposes to change the Dogecoin consensus, it must have been
+discussed extensively, be accompanied by widely discussed documentation and have
+a generally widely perceived technical consensus of being a worthwhile change,
+based on the judgement of the maintainers.

+# Installing Dogecoin Core
+
+### Pre-compiled binaries
+
+The easiest way to install the latest version of the Dogecoin Core software is
+by to download the latest precompiled binaries for your platform from the
+[release page](https://github.com/dogecoin/dogecoin/releases). Currently,
+binaries are released for the following platforms:
+
+- Windows, 64-bit and 32-bit
+- Linux, 64-bit and 32-bit
+- MacOS, Intel 64-bit
+- ARM, 64-bit and 32-bit Linux
+
+These binaries are created and verified by multiple independent people, to
+ensure honest and malware-free releases. See
+[the gitian building documentation](doc/gitian-building.md) for more information
+regarding that process.
+
+### Compiling using packaged dependencies
+
+It is possible to build your own copy of Dogecoin Core with the exact, tested,
+dependencies, as used for the binary releases, by using the
+[depends system](depends/description.md). Please refer to the
+[depends README](depends/README.md) for instructions to build Dogecoin using
+these dependencies.
+
+### Compiling using system-provided libraries
+
+  The following are developer notes on how to build Dogecoin on your native
+  platform, using the dependencies as provided by your system's package manager.
+  They are not complete guides, but include notes on the necessary libraries,
+  compile flags, etc.
+
+  - [Unix Build Notes](doc/build-unix.md)
+  - [Windows Build Notes](doc/build-windows.md)
+  - [macOS Build Notes](doc/Building-Dogecoin-1.14-for-Mac.md)
+
+### Testing
+
+Unit tests can be compiled and ran with `make check`. Further details on running
+and extending unit tests can be found in [/src/test/README.md](/src/test/README.md).
+
+There are also [regression and integration tests](/qa) written in Python, that
+are run automatically on the build server. These tests can be run (if the
+[test dependencies](/qa) are installed) with: `qa/pull-tester/rpc-tests.py`
+
+### Tips and tricks
+
+**compiling for debugging**
+
+Run `configure` with the `--enable-debug` option, then `make`. Or run `configure` with
+`CXXFLAGS="-g -ggdb -O0"` or whatever debug flags you need.
+
+**debug.log**
+
+If the code is behaving strangely, take a look in the debug.log file in the data directory;
+error and debugging messages are written there.
+
+The `-debug=...` command-line option controls debugging; running with just `-debug` will turn
+on all categories (and give you a very large debug.log file).
+
+The Qt code routes `qDebug()` output to debug.log under category "qt": run with `-debug=qt`
+to see it.
+
+**testnet and regtest modes**
+
+Run with the `-testnet` option to run with "play dogecoins" on the test network, if you
+are testing multi-machine code that needs to operate across the internet.
+
+If you are testing something that can run on one machine, run with the `-regtest` option.
+In regression test mode, blocks can be created on-demand; see qa/rpc-tests/ for tests
+that run in `-regtest` mode.
+
+**DEBUG_LOCKORDER**
+
+Dogecoin Core is a multithreaded application, and deadlocks or other multithreading bugs
+can be very difficult to track down. Compiling with `-DDEBUG_LOCKORDER` (`configure
+CXXFLAGS="-DDEBUG_LOCKORDER -g"`) inserts run-time checks to keep track of which locks
+are held, and adds warnings to the debug.log file if inconsistencies are detected.

+The JSON-RPC API provided by Dogecoin Core is self-documenting and can be browsed with `dogecoin-cli help`, while detailed information for each command can be viewed with `dogecoin-cli help <command>`. Alternatively, see the [Bitcoin Core documentation](https://developer.bitcoin.org/reference/rpc/) - which implement a similar protocol - to get a browsable version.

 ### Such ports
-RPC 22555
-P2P 22556

-![](http://dogesay.com/wow//////such/coin)
+Dogecoin Core by default uses port `22556` for peer-to-peer communication that
+is needed to synchronize the "mainnet" blockchain and stay informed of new
+transactions and blocks. Additionally, a JSONRPC port can be opened, which
+defaults to port `22555` for mainnet nodes. It is strongly recommended to not
+expose RPC ports to the public internet.
+
+| Function | mainnet | testnet | regtest |
+| :------- | ------: | ------: | ------: |
+| P2P      |   22556 |   44556 |   18444 |
+| RPC      |   22555 |   44555 |   18332 |
+
+## Ongoing development - Moon plan 🌒

+
+## 开发和贡献 – omg 开发者
+目前的研发还在进行中，开发团队以及其他志愿者可以随意通过自己的代码库分支发布pull request。
+
+#### 版本说明
+版本号码遵循以下语法：```major.minor.patch```。
+
+#### 代码库分支(branch)
+本代码库有3个branch：
+
+- **master（主代码库）:** 稳定。包含最新版本的release，以*major.minor*形式呈现。
+- **maintenance（维护代码库）:** 稳定。包含正在维护中的上一个release的最新版本。格式： ```<version>-maint```
+- **development（正在开发代码库）:** 不稳定。包含下一个release的最新代码。格式： ```<version>-dev```
+
+*Master 和 maintenance 互不干扰。最新release永远包含一个development分支。新的 pull request 应该发布于此。Maintenance 分支**只能用于调试程序**。请将新开发的功能发布在 development 分支的最高版本。*
+
+#### 贡献 ✍️
+
+鼓励开发者为新代码来创建自己的[单元测试](src/test/README.md)，或者为旧代码发布新的单元测试。用如下指令编译并运行单元测试（仅限于单元测试在配置中没有被禁用）：`make check`。更多关于运行和开发单元测试的信息请查看：[/src/test/README.md](/src/test/README.md).
+
+RPC界面上还有由Python编写的[回归和整合测试（regression and integration tests）](/qa) ，可以在build服务器上自动运行。这些测试还可以通过以下指令来运行：`qa/pull-tester/rpc-tests.py`（前提是已经安装了[测试依赖文件（test dependencies）](/qa)）。
+
+代码的改变还应该由除开发者之外的其他人员进行测试。这一点对于大段改动和高危变化尤其重要。建议在pull request的描述中加入测试文档(test plan)，如果测试方式并不很直接。
+
+## 灰常常见的问题 ❓
+
+### 到底一共可以有多少狗狗币? – 狗狗多多! 🐕
+截至2015年初（大概发行一年半的时间）会有100,000,000,000狗狗币。
+之后的每个区块（block）将会带来10,000狗狗币来激励矿工们持续输出，增加挖矿的安全性并且对因丢失的钱包、硬盘、手机、密码等而丢失的狗狗币做出相应弥补。 
+
+### 挖矿须知 ⛏
+
+狗狗币采用一种简化版的密钥派生函数作为它的工作量证明。目标时间为每分钟产出一个区块，每产出一个区块后都会进行难度值调整。区块奖励是固定的，且每产出100,000个区块就会减半。从第600,000个区块开始，每产出一个区块的奖励会固定在10,000个狗狗币。
+
+起初，我们设想了一种不同的支付方式，由Mersenne Twister伪随机数生成器在0到区块计划相应的最大区块奖励中生成一个随机数作为区块奖励。
+
+然而在第145,000区块上，为了防止大矿池钻空子只挖高奖励的区块，这种方案就不适用了。与此同时，难度值调整也从每4小时变为每个区块产生（每分钟）更改一次，使用的是DigiByte Coin开发团队的一个算法，以减少狗狗币网络中哈希率突然增大或减少带来的影响。
+
+**目前的区块奖励机制:**
+
+1–99,999: 0–1,000,000 Dogecoin
+
+100,000–144,999: 0–500,000 Dogecoin
+
+145,000–199,999: 250,000 Dogecoin
+
+200,000–299,999: 125,000 Dogecoin
+
+300,000–399,999: 62,500 Dogecoin
+
+400,000–499,999: 31,250 Dogecoin
+
+500,000–599,999: 15,625 Dogecoin
+
+600,000+: 10,000 Dogecoin
+
+**原先的区块奖励机制（一分钟区块和四小时难度调整）:**
+
+1–99,999: 0–1,000,000 Dogecoin
+
+100,000–199,999: 0–500,000 Dogecoin
+
+200,000–299,999: 0–250,000 Dogecoin
+
+300,000–399,999: 0–125,000 Dogecoin
+
+400,000–499,999: 0–62,500 Dogecoin
+
+500,000–599,999: 0–31,250 Dogecoin
+
+600,000+: 10,000 Dogecoin

+## 开发贴士与技巧
+
+**调试编译**
+
+运行 `configure`， 应用 `--enable-debug` 选项, 然后 `make`. 或者运行 `configure` 应用
+`CXXFLAGS="-g -ggdb -O0"` 或者其他你需要的flag。
+
+**debug.log**
+
+如果代码表现得很诡异，看一眼data路径下的debug.log；错误信息和调试消息都在这里。
+
+`-debug=...`这个选项代表调试模式；带着这个flag去运行会打开所有的类别（并输出一个非常大的debug.log文件）。
+
+Qt代码把 `qDebug()` 放到qt类别下的debug.log文件里；使用方式`-debug=qt`。
+
+**测试链（testnet）和私有网络（regtest）模式**
+
+如果你在通过因特网测试跨机代码，在测试链上运行`-testnet`来运行“开始使用狗狗币”。
+
+如果你在测试单机代码，用`-regtest`运行。
+在回归测试模式下，区块可以随时被按需制造出来；参见qa/rpc-tests/。
+
+**DEBUG_LOCKORDER**
+
+狗狗币核心是一个多线程应用，碰到死锁和其他多线程问题都会很难找到原因。如果在代码中发现了不一致的地方，使用-DDEBUG_LOCKORDER编译 (configure CXXFLAGS="-DDEBUG_LOCKORDER -g")会在运行时插入检查语句来检测哪些进程被锁定，并把警告加入debug.log文件中。

+# SYNOPSIS
+#
+#   AX_BOOST_BASE([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
+#
+# DESCRIPTION
+#
+#   Test for the Boost C++ libraries of a particular version (or newer)
+#
+#   If no path to the installed boost library is given the macro searchs
+#   under /usr, /usr/local, /opt and /opt/local and evaluates the
+#   $BOOST_ROOT environment variable. Further documentation is available at
+#   <http://randspringer.de/boost/index.html>.
+#
+#   This macro calls:
+#
+#     AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
+#
+#   And sets:
+#
+#     HAVE_BOOST

+# SYNOPSIS
+#
+#   AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
+#
+# DESCRIPTION
+#
+#   Check whether the given FLAG works with the current language's compiler
+#   or gives an error.  (Warnings, however, are ignored)
+#
+#   ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
+#   success/failure.
+#
+#   If EXTRA-FLAGS is defined, it is added to the current language's default
+#   flags (e.g. CFLAGS) when the check is done.  The check is thus made with
+#   the flags: "CFLAGS EXTRA-FLAGS FLAG".  This can for example be used to
+#   force the compiler to issue an error when a bad flag is given.
+#
+#   INPUT gives an alternative input source to AC_COMPILE_IFELSE.
+#
+#   NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
+#   macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

+# SYNOPSIS
+#
+#   AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional])
+#
+# DESCRIPTION
+#
+#   Check for baseline language coverage in the compiler for the specified
+#   version of the C++ standard.  If necessary, add switches to CXX and
+#   CXXCPP to enable support.  VERSION may be '11' (for the C++11 standard)
+#   or '14' (for the C++14 standard).
+#
+#   The second argument, if specified, indicates whether you insist on an
+#   extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
+#   -std=c++11).  If neither is specified, you get whatever works, with
+#   preference for an extended mode.
+#
+#   The third argument, if specified 'mandatory' or if left unspecified,
+#   indicates that baseline support for the specified C++ standard is
+#   required and that the macro should error out if no mode with that
+#   support is found.  If specified 'optional', then configuration proceeds
+#   regardless, after defining HAVE_CXX${VERSION} if and only if a
+#   supporting mode is found.

+# SYNOPSIS
+#
+#   AX_GCC_FUNC_ATTRIBUTE(ATTRIBUTE)
+#
+# DESCRIPTION
+#
+#   This macro checks if the compiler supports one of GCC's function
+#   attributes; many other compilers also provide function attributes with
+#   the same syntax. Compiler warnings are used to detect supported
+#   attributes as unsupported ones are ignored by default so quieting
+#   warnings when using this macro will yield false positives.
+#
+#   The ATTRIBUTE parameter holds the name of the attribute to be checked.
+#
+#   If ATTRIBUTE is supported define HAVE_FUNC_ATTRIBUTE_<ATTRIBUTE>.
+#
+#   The macro caches its result in the ax_cv_have_func_attribute_<attribute>
+#   variable.
+#
+#   The macro currently supports the following function attributes:
+#
+#    alias
+#    aligned
+#    alloc_size
+#    always_inline
+#    artificial
+#    cold
+#    const
+#    constructor
+#    constructor_priority for constructor attribute with priority
+#    deprecated
+#    destructor
+#    dllexport
+#    dllimport
+#    error
+#    externally_visible
+#    flatten
+#    format
+#    format_arg
+#    gnu_inline
+#    hot
+#    ifunc
+#    leaf
+#    malloc
+#    noclone
+#    noinline
+#    nonnull
+#    noreturn
+#    nothrow
+#    optimize
+#    pure
+#    unused
+#    used
+#    visibility
+#    warning
+#    warn_unused_result
+#    weak
+#    weakref
+#
+#   Unsuppored function attributes will be tested with a prototype returning
+#   an int and not accepting any arguments and the result of the check might
+#   be wrong or meaningless so use with care.

+# SYNOPSIS
+#
+#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro figures out how to build C programs using POSIX threads. It
+#   sets the PTHREAD_LIBS output variable to the threads library and linker
+#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+#   flags that are needed. (The user can also force certain compiler
+#   flags/libs to be tested by setting these environment variables.)
+#
+#   Also sets PTHREAD_CC to any special C compiler that is needed for
+#   multi-threaded programs (defaults to the value of CC otherwise). (This
+#   is necessary on AIX to use the special cc_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these flags,
+#   but also to link with them as well. For example, you might link with
+#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+#   If you are only building threaded programs, you may wish to use these
+#   variables in your default LIBS, CFLAGS, and CC:
+#
+#     LIBS="$PTHREAD_LIBS $LIBS"
+#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#     CC="$PTHREAD_CC"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+#   has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to
+#   that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+#   PTHREAD_CFLAGS.
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
+#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+#   is not found. If ACTION-IF-FOUND is not specified, the default action

+Repository Tools
+---------------------
+
+### [Developer tools](/contrib/devtools) ###
+Specific tools for developers working on this repository.
+Contains the script `github-merge.py` for merging GitHub pull requests securely and signing them using GPG.
+
+### [Verify-Commits](/contrib/verify-commits) ###
+Tool to verify that every merge commit was signed by a developer using the above `github-merge.py` script.
+
+### [Linearize](/contrib/linearize) ###
+Construct a linear, no-fork, best version of the blockchain.
+
+### [Qos](/contrib/qos) ###
+
+A Linux bash script that will set up traffic control (tc) to limit the outgoing bandwidth for connections to the Dogecoin network. This means one can have an always-on dogecoind instance running, and another local dogecoind/dogecoin-qt instance which connects to this node and receives blocks from it.
+
+### [Seeds](/contrib/seeds) ###
+Utility to generate the pnSeed[] array that is compiled into the client.
+
+Build Tools and Keys
+---------------------
+
+### [Debian](/contrib/debian) ###
+Contains files used to package dogecoind/dogecoin-qt
+for Debian-based Linux systems. If you compile dogecoind/dogecoin-qt yourself, there are some useful files here.
+
+### [Gitian-descriptors](/contrib/gitian-descriptors) ###
+Notes on getting Gitian builds up and running using KVM.
+
+### [Gitian-keys](/contrib/gitian-keys)
+PGP keys used for signing Dogecoin Core [Gitian release](/doc/release-process.md) results.
+
+### [MacDeploy](/contrib/macdeploy) ###
+Scripts and notes for Mac builds.
+
+### [RPM](/contrib/rpm) ###
+RPM spec file for building dogecoin-core on RPM based distributions
+
+### [Gitian-build](/contrib/gitian-build.sh) ###
+Script for running full Gitian builds.
+
+### [Snap](/contrib/snap) ###
+snapcraft.yaml file for building and distributing dogecoin-core with Snapcraft.
+
+Test and Verify Tools
+---------------------
+
+### [TestGen](/contrib/testgen) ###
+Utilities to generate test vectors for the data-driven Dogecoin tests.
+
+### [Verify Binaries](/contrib/verifybinaries) ###
+This script attempts to download and verify the signature file SHA256SUMS.asc from dogecoin.com.

+##            Quick Primer on addnode vs connect            ##
+##  Let's say for instance you use addnode=4.2.2.4          ##
+##  addnode will connect you to and tell you about the      ##
+##    nodes connected to 4.2.2.4.  In addition it will tell ##
+##    the other nodes connected to it that you exist so     ##
+##    they can connect to you.                              ##
+##  connect will not do the above when you 'connect' to it. ##
+##    It will *only* connect you to 4.2.2.4 and no one else.##
+##                                                          ##
+##  So if you're behind a firewall, or have other problems  ##
+##  finding nodes, add some using 'addnode'.                ##
+##                                                          ##
+##  If you want to stay private, use 'connect' to only      ##
+##  connect to "trusted" nodes.                             ##
+##                                                          ##
+##  If you run multiple nodes on a LAN, there's no need for ##
+##  all of them to open lots of connections.  Instead       ##
+##  'connect' them all to one node that is port forwarded   ##
+##  and has lots of connections.                            ##

+#rpcuser=Ulysseys
+#rpcpassword=YourSuperGreatPasswordNumber_DO_NOT_USE_THIS_OR_YOU_WILL_GET_ROBBED_385593
+#
+# The second method `rpcauth` can be added to server startup argument. It is set at intialization time

+# Your password:
+# DONT_USE_THIS_YOU_WILL_GET_ROBBED_8ak1gI25KFTvjovL3gAM967mies3E=
+#
+# On client-side, you add the normal user/password pair to send commands:
+#rpcuser=alice
+#rpcpassword=DONT_USE_THIS_YOU_WILL_GET_ROBBED_8ak1gI25KFTvjovL3gAM967mies3E=
+#
+# You can even add multiple entries of these to the server conf file, and client can use any of them:

-.TH BITCOIND "1" "January 2011" "bitcoind 3.19" 
-.SH NAME
-bitcoind \- peer-to-peer network based digital currency
-.SH SYNOPSIS
-bitcoin [options] <command> [params]  
-.TP
-bitcoin [options] help <command> \- Get help for a command
-.SH DESCRIPTION
-This  manual page documents the bitcoind program. Bitcoin is a peer-to-peer digital currency. Peer-to-peer (P2P) means that there is no central authority to issue new money or keep track of transactions. Instead, these tasks are managed collectively by the nodes of the network. Advantages:
-
-Bitcoins can be sent easily through the Internet, without having to trust middlemen. Transactions are designed to be irreversible. Be safe from instability caused by fractional reserve banking and central banks. The limited inflation of the Bitcoin system’s money supply is distributed evenly (by CPU power) throughout the network, not monopolized by banks.

+Contents
+========
+This directory contains tools for developers working on this repository.
+
+check-doc.py
+============
+
+Check if all command line args are documented. The return value indicates the
+number of undocumented args.
+
+clang-format-diff.py
+===================
+
+A script to format unified git diffs according to [.clang-format](../../src/.clang-format).
+
+For instance, to format the last commit with 0 lines of context,
+the script should be called from the git root folder as follows.
+
+```
+git diff -U0 HEAD~1.. | ./contrib/devtools/clang-format-diff.py -p1 -i -v
+```
+
+copyright\_header.py
+====================
+
+Provides utilities for managing copyright headers of `The Bitcoin Core
+developers` in repository source files. It has three subcommands:
+
+```
+$ ./copyright_header.py report <base_directory> [verbose]
+$ ./copyright_header.py update <base_directory>
+$ ./copyright_header.py insert <file>
+```
+Running these subcommands without arguments displays a usage string.
+
+copyright\_header.py report \<base\_directory\> [verbose]
+---------------------------------------------------------
+
+Produces a report of all copyright header notices found inside the source files
+of a repository. Useful to quickly visualize the state of the headers.
+Specifying `verbose` will list the full filenames of files of each category.
+
+copyright\_header.py update \<base\_directory\> [verbose]
+---------------------------------------------------------
+Updates all the copyright headers of `The Bitcoin Core developers` which were
+changed in a year more recent than is listed. For example:
+```
+// Copyright (c) <firstYear>-<lastYear> The Bitcoin Core developers
+```
+will be updated to:
+```
+// Copyright (c) <firstYear>-<lastModifiedYear> The Bitcoin Core developers
+```
+where `<lastModifiedYear>` is obtained from the `git log` history.
+
+This subcommand also handles copyright headers that have only a single year. In
+those cases:
+```
+// Copyright (c) <year> The Bitcoin Core developers
+```
+will be updated to:
+```
+// Copyright (c) <year>-<lastModifiedYear> The Bitcoin Core developers
+```
+where the update is appropriate.
+
+copyright\_header.py insert \<file\>
+------------------------------------
+Inserts a copyright header for `The Bitcoin Core developers` at the top of the
+file in either Python or C++ style as determined by the file extension. If the
+file is a Python file and it has  `#!` starting the first line, the header is
+inserted in the line below it.
+
+The copyright dates will be set to be `<year_introduced>-<current_year>` where
+`<year_introduced>` is according to the `git log` history. If
+`<year_introduced>` is equal to `<current_year>`, it will be set as a single
+year rather than two hyphenated years.
+
+If the file already has a copyright for `The Bitcoin Core developers`, the
+script will exit.
+
+gen-manpages.sh
+===============
+
+A small script to automatically create manpages in ../../doc/man by running the release binaries with the -help option.
+This requires help2man which can be found at: https://www.gnu.org/software/help2man/
+
+git-subtree-check.sh
+====================
+
+Run this script from the root of the repository to verify that a subtree matches the contents of
+the commit it claims to have been updated to.
+
+To use, make sure that you have fetched the upstream repository branch in which the subtree is
+maintained:
+* for `src/secp256k1`: https://github.com/bitcoin-core/secp256k1.git (branch master)
+* for `src/leveldb`: https://github.com/bitcoin-core/leveldb.git (branch bitcoin-fork)
+* for `src/univalue`: https://github.com/bitcoin-core/univalue.git (branch master)
+* for `src/crypto/ctaes`: https://github.com/bitcoin-core/ctaes.git (branch master)
+
+Usage: `git-subtree-check.sh DIR (COMMIT)`
+
+`COMMIT` may be omitted, in which case `HEAD` is used.
+
+github-merge.py
+===============
+
+A small script to automate merging pull-requests securely and sign them with GPG.
+
+For example:
+
+  ./github-merge.py 3077
+
+(in any git repository) will help you merge pull request #3077 for the
+bitcoin/bitcoin repository.
+
+What it does:
+* Fetch master and the pull request.
+* Locally construct a merge commit.
+* Show the diff that merge results in.
+* Ask you to verify the resulting source tree (so you can do a make
+check or whatever).
+* Ask you whether to GPG sign the merge commit.
+* Ask you whether to push the result upstream.
+
+This means that there are no potential race conditions (where a
+pullreq gets updated while you're reviewing it, but before you click
+merge), and when using GPG signatures, that even a compromised GitHub
+couldn't mess with the sources.
+
+Setup
+---------
+Configuring the github-merge tool for the bitcoin repository is done in the following way:
+
+    git config githubmerge.repository bitcoin/bitcoin
+    git config githubmerge.testcmd "make -j4 check" (adapt to whatever you want to use for testing)
+    git config --global user.signingkey mykeyid (if you want to GPG sign)
+
+optimize-pngs.py
+================
+
+A script to optimize png files in the bitcoin
+repository (requires pngcrush).
+
+security-check.py and test-security-check.py
+============================================
+
+Perform basic ELF security checks on a series of executables.
+
+symbol-check.py
+===============
+
+A script to check that the (Linux) executables produced by gitian only contain
+allowed gcc, glibc and libstdc++ version symbols. This makes sure they are
+still compatible with the minimum supported Linux distribution versions.
+
+Example usage after a gitian build:
+
+    find ../gitian-builder/build -type f -executable | xargs python contrib/devtools/symbol-check.py 
+
+If only supported symbols are used the return value will be 0 and the output will be empty.
+
+If there are 'unsupported' symbols, the return value will be 1 a list like this will be printed:
+
+    .../64/test_bitcoin: symbol memcpy from unsupported version GLIBC_2.14
+    .../64/test_bitcoin: symbol __fdelt_chk from unsupported version GLIBC_2.15
+    .../64/test_bitcoin: symbol std::out_of_range::~out_of_range() from unsupported version GLIBCXX_3.4.15
+    .../64/test_bitcoin: symbol _ZNSt8__detail15_List_nod from unsupported version GLIBCXX_3.4.15
+
+update-translations.py
+======================
+
+Run this script from the root of the repository to update all translations from transifex.
+It will do the following automatically:
+
+- fetch all translations
+- post-process them into valid and committable format
+- add missing translations to the build system (TODO)
+
+See doc/translation-process.md for more information.

-gitian-builder now also supports building using LXC. See
-  https://help.ubuntu.com/12.04/serverguide/lxc.html
-... for how to get LXC up and running under Ubuntu.
-
-If your main machine is a 64-bit Mac or PC with a few gigabytes of memory
-and at least 10 gigabytes of free disk space, you can gitian-build using
-LXC running inside a virtual machine.
-
-Here's a description of Gavin's setup on OSX 10.6:
-
-1. Download and install VirtualBox from https://www.virtualbox.org/
-
-2. Download the 64-bit Ubuntu Desktop 12.04 LTS .iso CD image from
-  http://www.ubuntu.com/
-
-3. Run VirtualBox and create a new virtual machine, using the
-  Ubuntu .iso (see the VirtualBox documentation for details).
-  Create it with at least 2 gigabytes of memory and a disk
-  that is at least 20 gigabytes big.
-
-4. Inside the running Ubuntu desktop, install:
-  sudo apt-get install debootstrap lxc ruby apache2 git apt-cacher-ng python-vm-builder
-
-5. Still inside Ubuntu, tell gitian-builder to use LXC, then follow the "Once you've got the right

-  export USE_LXC=1
