# 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 networks for decades.

The protocol has since stagnated, largely abandoned except by a small cult of
millenarians. A growing number of proprietary cloud services have filled the
vacuum of innovation. Free software projects are relegated to collaborating on
non-free platforms for a basic rich user experience. The consensus is that
decentralization is needed, and users not be limited to some arcane
retro-environment.

**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. Your privacy and security matters. We encourage
you to contribute new ideas and are liberal in accepting experimental features.

### 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.

4. See the [TUNING](doc/TUNING.md) guide to optimize Construct for your deployment.

##### 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.

## Roadmap

##### FEATURE EXPERIENCE

- [x] Phase One: **Matrix clients** using HTTPS.
- [ ] Phase Two: Legacy IRC network **TS6 protocol**.

##### TECHNOLOGY

- [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.

##### DEPLOYMENT

```
Operating a Construct server which is open to public user registration is unsafe. Local users may
be able to exceed resource limitations and deny service to other users.
```

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

> Due to the breadth of the Matrix client/server protocol we can only endorse
production use of Construct gradually while local user restrictions are
developed. This notice applies to locally registered users connecting with
clients, it does not apply to federation.
