Commit conventions

Commit parsing

A commit message must be parsed in the following way:

[HEADER] Verb + short description

- precision 1
- precision 2
- ...

Commit header

To specify changes made during commit, the header must be one of these items:

• [DEV] Basic development
• [FEAT] Add a new feature to the package
• [DOC] Add documentation
• [FIX] Fix a bug
• [LINT] Code linting
• [CORE] Core development (new module, etc.)
• [TEST] Add unit-test

These headers are just a convention, and should be improved thanks to the contributors' remarks.
