How to contribute

First of all, thanks for your interest in contributing to this project!

Guidelines

Here are some guidelines to keep in mind when contributing:

Please try to limit each pull request to one change, as this makes it much easier to manage; small pull requests are fine :)
Please make sure that the tests pass, including EPUBCheck (see README.md for more information on EPUBCheck)
If you're adding new features, please add new tests to cover them
Please try to avoid making breaking changes to the API; it would be preferable to add a new method for a new feature rather than modify an existing one
Please document any newly-added public methods

Optional

These are nice as well, although they won't prevent a pull request from getting merged:

This project uses go fmt for formatting
This project uses Conventional Commits
This project uses examples where useful to make the documentation more clear

Cheers!
