# This — is The **Construct**

It all started in 1988 when Jarkko Oikarinen developed a free and open source server
at the University of Oulu which facilitated real-time communication over the internet.
Its [derivatives](https://upload.wikimedia.org/wikipedia/commons/d/d8/IRCd_software_implementations.png)
have underpinned the major chat networks for decades ever since.

Due to their age and stagnation since the mid-2000's, a growing number of
proprietary cloud services have filled the vacuum of innovation. In 2014 a new
approach was proposed to reinvigorate real-time communication for free and open
source software: a *federation of networks* known as *the matrix*.

**This is the Construct** — the community's own Matrix server. It is designed to be
fast and highly scalable, and to be developed by volunteer contributors over
the internet. This mission strives to make the software easy to understand, modify, audit,
and extend. It remains true to its roots with its modular design and having minimal
requirements. Even though all of the old code has been rewritten, the same spirit and
_philosophy of its predecessors_ is still obvious throughout.

Matrix is about giving you control over your communication; Construct is about
giving you control over Matrix.

### Getting Started

1. At this phase of development the best thing to do is pull the master branch
and use the latest head.

2. See the [BUILD](doc/BUILD.md) instructions to compile Construct from source.

3. See the [SETUP](doc/SETUP.md) instructions to run Construct for the first time.

##### TROUBLESHOOTING

See the [TROUBLESHOOTING](doc/TROUBLESHOOTING.md) guide for solutions to possible
problems.

##### DOCUMENTATION

Generate doxygen using `/usr/bin/doxygen tools/doxygen.conf` the target
directory is `doc/html`. Browse to `doc/html/index.html`.

##### ARCHITECTURE GUIDE

See the [ARCHITECTURE](doc/ARCHITECTURE.md) summary for design choices and
things to know when starting out.

##### DEVELOPMENT STYLE GUIDE

See the [STYLE](doc/STYLE.md) guide for an admittedly tongue-in-cheek lecture on
the development approach.

## Plan

#### Roadmap for service

- [x] **Phase One**: Matrix clients using HTTPS.
- [ ] **Phase Two**: Legacy IRC network TS6 protocol.
- [ ] **Phase Three**: Legacy IRC clients using RFC1459 / RFC2812 legacy grammars.

#### Roadmap for deployments

The deployment mode is a macro of configuration variables which tune the daemon
for how it is being used. Modes mostly affect aspects of local clients.

- [x] **Personal**: One or few users. Few default restrictions; higher log output.
- [ ] **Company**: Hundreds of users. Moderate default restrictions.
- [ ] **Public**: Thousands of users. Untrusting configuration defaults.

#### Roadmap for innovation

- [x] Phase Zero: **Core libircd**: Utils; Modules; Contexts; JSON; Database; HTTP; etc...
- [x] Phase One: **Matrix Protocol**: Core VM; Core modules; Protocol endpoints; etc...
- [ ] Phase Two: **Construct Cluster**: Kademlia sharding of events; Maymounkov's erasure codes.
