-# Contribution Guidelines
+# Contributing
+
+I am very happy if you would like to provide a pull request 👍
+
+The content of this file describes which requirements contributors should fulfill before submitting a pull request (PR).
+
+1. [Valid Git commits](#valid-git-commits)
+
+## Valid Git commits
+
+### Commit message
+
+The repository is subject to a strict commit message template. This states that there are several types of commits. For
+example, `fix`, `chore`, `refac`, `test` or `doc`. All types are described in more detail below.
+
+| type                | description                                                       |
+| ------------------- | ----------------------------------------------------------------- |
+| `feat`              | New feature.                                                      |
+| `fix`               | Fixes a bug.                                                      |
+| `refac`             | Refactoring production code.                                      |
+| `style`             | Fixes formatting issues. No production code change.               |
+| `docs`              | Adapt documentation. No production code change.                   |
+| `test`              | Adds new or modifies existing tests. No production code change.   |
+| `chore`             | Updating grunt tasks. Is everything which the user does not see.  |
+
+Based on these types, commit messaged can then be created. Here are a few examples:
+
+```text
+style(README): Wrong indentation
+feat(deployment): support restartPolicy
+fix(my-app): Add missing volume
+docs(CONTRIBUTING): Describe how to commit correctly
+```
+
+This type of commit message makes it easier for me as maintainer to keep an overview and does not cause the commits of a
+pull request PR to be combined into one commit (squashing).
+
+### Smart commits
+
+Smart commits are excellent when it comes to tracking bugs or issues. In this repository, however, the rebasing of
+commits is prohibited, which means that only merge commits are possible. This means that a smart commit message only
+needs to be added to the merge commit.
+
+This has the advantage that the maintainer can use the smart commit to find the merge commit and undo the entire history
+of a merge without having to select individual commits. The following history illustrates the correct use of smart commits.
+
+```text
+* 823edbc7 Volker Raschek (G) | [Close #2] feat(deployment): support additional containers
+|\
+| * 321aebc3 Volker Raschek (G) | doc(README): generate README with new deployment attributes
+| * 8d101dd3 Volker Raschek (G) | test(deployment): Extend unittest of additional containers
+| * 6f2abd93 Volker Raschek (G) | fix(deployment): Extend deployment of additional containers
+|/
+* aa5ebda bob (N) | [Close #1] feat(deployment): support initContainers
+```
+
+### Commit signing
+
+Another problem with Git is the chain of trust. Git allows the configuration of any name and e-mail address. An attacker
+can impersonate any person and submit pull requests under a false identity. For as Linux Torvalds, the maintainer of the
+Linux kernel.
+
+```bash
+git config --global user.name 'Linux Torvalds'
+git config --global user.email 'torvalds@linux-foundation.org'
+```
+
+To avoid this, some Git repositories expect signed commits. In particular, repositories that are subject to direct
+delivery to customers. For this reason, the repository is subject to a branch protection rule that only allows signed
+commits. *Until* there is *no verified* and *no signed* commit, the pull request is blocked.
+
+The following articles describes how Git can be configured to sign commits. Please keep in mind, that the e-mail
+address, which is used as UID of the GPG keyring must also be defined in the profile settings of your GitHub account.
+Otherwise will be marked the Git commit as *Unverified*.
+
+1. [Signing Commits](https://docs.github.com/en/authentication/managing-commit-signature-verification/signing-commits)
+2. [Tell Git about your signing key](https://docs.github.com/en/authentication/managing-commit-signature-verification/telling-git-about-your-signing-key)
+
+Inspect your Git commit via `git log`. There should be mentioned, that your commit is signed.
+
+Furthermore, the GPG key is unique. **Don't loose your private GPG key**. Backup your private key on a safe device. For
+example an external USB drive.
