# Description

This is a minimal REST API intended for use with a Continuous Integration system for managing comments on GitHub.

The problem this solves is posting comments in a PR from multiple builds without spamming the comment section. Instead we post just one comment with a table and continue to update it.

# Example Comment

# API

It exposes just 1 call:

* `POST /builds/:id` - Post a comment for PR with given ID.
* `POST /builds/:id/refresh` - Update the comment for PR with given ID.
* `POST /comments` - Show currently managed comments in PRs.

By default it listens on `localhost:8080`.
