+## Blog Posts - More Information About This Repo
+
+You can find more information about this project/repository and how to use it in following blog post:
+
+- _Soon..._
+
+## Quick Start
+
+To use this repository as starter for your project you can run configure_project.sh script, which sets up all variables and file names. This way you can avoid configuring and renaming things yourself:
 
 ```bash
-docker run --rm --name go-github-app \
-    -v $(pwd)/config:/config \
-    -p 8080:8080 \
-    ghcr.io/martinheinz/go-github-app/app
+./configure_project.sh \
+    APP_ID="54321" \
+    INSTALLATION_ID="987654321" \
+    WEBHOOK_SECRET="verysecret" \
+    KEY_PATH="./github_key.pem" \
+    REGISTRY="ghcr.io/<GITHUB_USERNAME>/go-github-app"
 ```
+
+## Running
+
+```bash
+make container  # Builds containerized application
+make run        # Runs container at localhost
+
+# From another terminal:
+curl http://localhost:8080/api/v1/github/pullrequests/octocat/hello-world
+```
+
+## Testing
+
+Test are run inside container image, equivalent to the container in which the application runs. To run tests:
+
+```bash
+make test

+## CI/CD
+
+Predefined CI/CD uses GitHub Actions:
+
+- _Build, Test, Lint_ Workflow (`build.yaml`):
+    - Builds binary and container image
+    - Runs tests and generates code coverage report
+    - Performs SonarCloud code analysis
+    - Sends coverage starts to CodeClimate
+
+- _Release_ Workflow (`release.yaml`, triggered on _tag_ creation):
+    - Builds container image
+    - Pushes the image to GitHub container registry
