Create a GitHub account for issues and pull requests.
Find an issue to work on or optionally create one that describes the work that you want to do.
[Fork] and [clone] the GitHub repository that you want to contribute to.
Create a branch in the local clone of your fork.

    git checkout -b accumulo-4321

Do work and commit to your branch. You can reference [this link][messages] for a guide on how to write good commit log messages.
Ensure you works satisfies the guidelines laid out in the CONTRIBUTING.md file.
If needed, squash to the minimum number of commits. For help on squashing commits, see this [tutorial][squash-tutorial] or [StackOverflow answer][squash-stack].
[Push] your branch to your fork.

    git push origin accumulo-4321

Create a [Pull Request] on GitHub to the appropriate repository. A [draft pull request] can be used if the work is not complete.
At least one committer (and others in the community) will review your pull request and add any comments to your code.
Push any changes from the review to the branch as new commits so the reviewer only needs to review new changes. Please avoid squashing commits after the review starts. Squashing makes it hard for the reviewer to follow the changes.
Repeat this process until a reviewer approves the pull request.
When the review process is finished, all commits on the pull request may be squashed by a committer. Please avoid squashing as it makes it difficult for the committer to know if they are merging what was reviewed.

Accumulo follows [semver] for its public API.
Every file requires the ASF license header as described in [ASF Source Header][srcheaders].
Do not use Author Tags. The code is developed and owned by the community.
