+## Coding Guidelines
+
+- The terraform language has some [style conventions](https://developer.hashicorp.com/terraform/language/syntax/style) which must be followed for consistency between files and modules written by different teams.
+
+## Opening a pull request
+
+- We require pull request titles to follow the [conventional commits specification](https://www.conventionalcommits.org/en/v1.0.0/)
+
+- Labels are automatically added to your PR based on certain keywords in the `title`, `body`, and `branch` . You are able to manually add or remove labels from your PR, the following labels are allowed: `breaking`, `enhancement`, `feature`, `bug`, `fix`, `security`, `documentation`.
+
+## Release flow
+
+1. Every time a PR is merged, a draft release note is created or updated to add an entry for this PR. The release version is automatically incremented based on the labels specified.
+
+2. When you are ready to publish the release, you can use the drafted release note to do so. `MCAF Contributors` are able to publish releases. If you are an `MCAF Contributor` and want to publish a drafted release:
+    - Browse to the release page
+    - Edit the release you want to publish (click on the pencil)
+    - Click `Update release` (the green button at the bottom of the page)
+
+If a PR should not be added to the release notes and changelog, add the label `no-changelog` to your PR.
+
+## Local Development
+
+To ease local development, [pre-commit](https://pre-commit.com/) configuration has been added to the repository. Pre-commit is useful for identifying simple issues before creating a PR:
+
+To use it, follow these steps:
+
+1. Installation:
+    - Using Brew: `brew install tflint`
+    - Using Python: `pip3 install pre-commit --upgrade`
+    - Using Conda: `conda install -c conda-forge pre-commit`
+
+2. Run the pre-commit hooks against all the files (the first time run might take a few minutes):
+`pre-commit run -a`
+
+3. (optional) Install the pre-commit hooks to run before each commit:
+`pre-commit install`
