+# Config Commitlint
+
+Commitlint configuration used at flagbit
+
+## How can I use this in my project?
+
+Create a new file named `commitlint.config.js` in your projects root directory,
+including this content:
+
+```javascript
+module.exports = {
+  extends: ["@flagbit/config-commitlint"],
+  parserPreset: {
+    parserOpts: {
+      issuePrefixes: ["FBTLOPS-"],
+    },
+  },
+};
+```
+
+...add (or extend an existing) Makefile to include a `lint` target:
+
+```makefile
+.DEFAULT_GOAL := lint
+GITHUB_BASE_REF ?= master
+
+.PHONY: lint
+lint:
+	commitlint -g index.js --from=$$(git rev-parse remotes/origin/$(GITHUB_BASE_REF))
+```
+
+...and finally add a github-workflow to your project by placing a file named
+`commitlint.yml` to the `.github/workflows/`-directory in your project. If this
+directory is not existing, then you can simply create it. The `commitlint.yml`
+needs to include this content:
+
+```yml
+name: commitlint
+on: pull_request
+
+jobs:
+  commitlint:
+    name: Lint Commit Messages
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v2
+        with:
+          fetch-depth: 0
+      - run: |
+          yarn global add @commitlint/cli @flagbit/config-commitlint 
+          echo "$(yarn global bin)" >> $GITHUB_PATH
+      - run: make lint
+```
