We use GitHub issues to communicate development ideas. The simplest way to contribute to Merlin is to leave comments on our GitHub issues.
We follow a process of lazy consensus. If you believe you know what the project needs then just start development. If you are unsure about which direction to take with development then please communicate your ideas through a GitHub issue before starting development.
Please submit a PR to the master branch of the Merlin repository once you are ready to submit your contribution. Once submitted, GitHub Actions will run a range of tests to verify the submission, after which community members will help to review the pull request. Pull request to Merlin (including a submission from project maintainers) requires review and approval from maintainers.
