First rule, abide by code-of-conduct.md.
If anyone want's to contribute or for me to change/add/remove anything I'll be deligthed.
Try and keep the coverage to 90% (green badge on coveralls). Also, make sure you are using latest versions of modules where possible. Add tests for new features or changes to existing code.
To ensure your changes meet the quality expectations, it is advised to use the pre-commit hook. In your terminal, run
this command cp pre-commit ./.git/hooks/.
Make sure you bump up the package version and add an entry to CHANGELOG.md.
