+### Semantic Commit Messages
+
+We use [semantic commit messages](https://www.conventionalcommits.org/en/v1.0.0/)  in this repository.
+
+They follow this format: `<type>[optional scope]: <description>`
+
+Examples for commit messages following this are:
+
+`feat: allow provided config object to extend other configs`
+
+You can also include a scope within parenthesis:
+
+`fix(scope): Prevent wrong calculation of storage`
+
+Here's a list of types that we use:
+
+| Type | Explanation |
+|---|---|
+| feat | A new feature |
+| fix | A bug fix |
+| docs | Documentation only changes |
+| style | Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc) |
+| refactor | A code change that neither fixes a bug nor adds a feature |
+| perf |  A code change that improves performance |
+| test | Adding missing tests or correcting existing tests |
+| build |Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm) |
+| ci | Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs) |
+| chore | Other changes that don't modify src or test files |
+| revert | Reverts a previous commit |
+
