+# Introduction
+
+Thank you for your interest in DZGUI!
+
+This guide goes over development conventions and best practices for contributors.
+If you are a developer, you can skip to the end.
+
+# Requesting help
+
+If you encounter a problem with DZGUI, you can submit tickets on the GitHub
+(issue tracker)[https://github.com/aclist/dzgui-devel/issues] under the
+`troubleshooting` tag.
+
+# How can I help the project?
+
+There are several ways to help this project.
+1. Report bugs that you find
+2. Request features that you would like
+3. Contribute features and fixes to the codebase
+4. Contribute documentation to the project
+
+Before making any contribution, please read the `CODE_OF_CONDUCT.md` and act
+accordingly.
+
+## Submitting a ticket
+
+Navigate to the GitHub (issue tracker)[https://github.com/aclist/dzgui-devel/issues].
+From there, follow the onscreen prompts. You will be asked questions such as:
+
+- What version are you using?
+- What distribution are you using?
+- What is the issue that you found?
+- How can we reproduce the issue?
+
+You can also attach screenshots, logs, or other data that can help us.
+
+## Requesting a feature
+
+You can also request features via the same issue tracker. It is good practice to
+first search for your idea to see if a similar one has already been posted.
+If not, open a ticket where you describe your feature and its possible benefits.
+
+Please note that this is a community project, so it takes time for us to develop
+features. Putting in a feature request does not mean that it will be implemented,
+but we will do our best to support as many cool ideas as possible.
+
+## Contributing code or documentation
+
+If you would like to take ownership or assist with an issue on the issue tracker, or
+contribute a new change, please follow the guidelines below.
+
+Fork this repository and check out the code up to `prerelease/<latest-version>`.
+If there is no pending prerelease PR, you can base your changes off of
+the `testing` branch. You may later be asked to retarget your PR to the prerelease
+branch once a new one is made. This is because out-of-band PRs are consolidated into
+the next release before merging.
+
+The following naming conventions apply for PRs:
+- fix/<your-fix> - patch/hotfix branches
+- feat/<your-feature> - feature branches
+- doc/<your-doc-branch> - documentation branches
+- infra/<your-infra-branch> - infrastructure branches
+
+Implement your changes and test them locally. If they work you may
+open a merge request, and then we review your changes. If everything is OK, it
+will be merged to `prerelease/<latest-version>`, then `testing`, and after a live
+testing phase, to `stable` as well.
+
+It is recommended to follow
+(Conventional Commits)[https://www.conventionalcommits.org/en/v1.0.0/], as this
+integrates well with tooling and helps the project review your code.
