+## 🐳 GitHub Container Registry (GHCR) Image
+A Docker image is automatically built and published to GitHub Container Registry (GHCR) on every push to the `main` branch.
+
+### Serving it yourself
+By default, `docker-compose.yml` can use the published image from GHCR:
 ```
 git clone git@github.com:SolitudePy/LinuxForensicsLearn.git
 cd LinuxForensicsLearn
 docker compose build
 docker compose up -d
 ```
+This will pull the image from GHCR if you do not build locally.
+
+### Build Locally (Optional)
+If you want to build the image yourself (for local development or custom changes), you can use the `build` option in your `docker-compose.yml`:
+
+```
+services:
+  jekyll-forensics:
+    build:
+      context: .
+      dockerfile: Dockerfile
+    # ...other options...
+```
+
+If both `build` and `image` are specified, Compose will build the image locally and use it instead of pulling from GHCR.
