Start by cloning the project and make sure that it is able to build and all tests are green.
This repository uses automated deployment and versioning. To do this we use the tool semantic-release which analyses commit messages to determine a release and generate a changelog. The commit message format we use is Conventional Commits. Please use this format for all commit messages to ensure correct versioning and changelog generation.
When the bug have been solved or the feature added (and tested!) create a Pull Request. This will do testing and your contribution is ready for review.
