 Always try to split up your changes into coherent commits, a single commit should do a single thing. If your commit needs to do more than one thing it should be labeled with the type coming first in this list.
 
 Special cases are **merge commits** and **revert commits**. Git provides a default commit message for these two cases, just leave them if you do nothing else to the committed files.
 
+##### Retired Types
+
+You might find the following types in the git history but their use is discouraged in favor of another type:
+
+| type  | description                                     | replaced by |

+| `doc` | updating documentation, including code comments | `meta`      |

 #### Git Hooks
 
 This project uses [Husky](https://github.com/typicode/husky) to define git hooks. The point of the pre-commit hook is to have a clean commits. This means correctly formatted, without linter errors and functioning tests. The `npm run fix` script fixes all fixable errors, the tests you have to fix yourself.
