Mastodon
========
Mastodon is a federated microblogging engine. An alternative implementation of the GNU Social project. Based on ActivityStreams, Webfinger, PubsubHubbub and Salmon.
The core ideals of this project are:
- Independence of legacy Twitter APIs - we don't want to be compatible with Twitter clients, we want our own clients
- In that vein, a strong and clean REST API and OAuth2
- Minimalism. Just because you can do almost anything with ActivityStreams doesn't mean you should. Limit the set of possible functions to what makes sense in a microblogging engine. This will make federation as well as UI design a lot easier
- Ease of deployment. The end-goal of this project is to be distributable as a Docker image.
**Current status of the project is early development. Documentation, licensing information &co will be added later**
