+# Contributing
+
+## Commit message format
+
+All commit messages should follow the [Conventional Commits][commits] format.
+This format allows us to automatically generate changelogs and version numbers
+based on the commit messages.
+
+Common commit types include:
+
+* `fix`: A bug fix
+* `feat`: A new feature
+* `ci`: Changes to CI/CD
+* `docs`: Changes to documentation
+
+adding `!` after the type indicates a breaking change. For example, `feat!`
+would indicate a new feature that breaks existing functionality, and would
+therefore require a major version bump.
+
+`bump` is a special type used to indicate a version bump. This is used by the
+automated release process, and should be avoided in normal commits.
+
+## Coding standards
+
+Code should follow the [OpenTofu style conventions][style]. This ensures that
+all code is consistent and easy to read and maintain.
+
+To make resources easier to find, you may group them together in a single file
+within your module. For example, while `main.tf` handles the main configuration,
+you may create a `dns.tf` file to handle all DNS-related resources.
+
+Additionally, the following should be grouped together within their own files:
+
+* `data.tf` for data sources
+* `local.tf` for local values
+* `output.tf` for outputs
+
+## Code reviews
+
+All code should be contributing in the form of a pull request. Pull requests
+should have an approval from _at least_ one required reviewer as defined in the
+`CODEOWNERS` file. Additional reviews are welcome, and may be requested by
+either the submitter or the required reviewer.
