 ### Branch structure

 We have two main branches:

-*   `master` represents the most recently released (published on npm) version of the codebase.
-*   `development` represents the current development state of the codebase.
+-   `master` represents the most recently released (published on npm) version of the codebase.
+-   `development` represents the current development state of the codebase.

 ALL PRs should be opened against `development`.

 Branch names should be prefixed with `fix`, `feature` or `refactor`.

-*   e.g `fix/broken-wiki-link`
-*   If the PR only edits a single package, add it's name too
-    *   e.g `fix/website/broken-wiki-link`
+-   e.g `fix/broken-wiki-link`
