 ### Running CeWL in a Docker container
 
 To quickly use CeWL on your machine with Docker, you have to build it :
-1. Build the container :
+
+1. Optionally build the image locally so it is ready to use:
     ```sh
-    docker build -t cewl .
+    docker compose build
     ```
 2. Container usage without interacting with local files :
     ```sh
-    docker run -it --rm cewl [OPTIONS] ... <url>
+	docker run -it --rm ghcr.io/digininja/cewl http://dvwa.test
     ```
 3. Container usage with local files as input or output :
     ```sh
     # you have to mount the current directory when calling the container 
-    docker run -it --rm -v "${PWD}:/host" cewl [OPTIONS] ... <url>
+    docker run -it --rm -v "${PWD}:/host" ghcr.io/digininja/cewl [OPTIONS] ... <url>
     ```
 
 I am going to stress here, I am not going to be offering any support for this. The work was done by [@loris-intergalactique](https://github.com/loris-intergalactique) who has offered to field any questions on it and give support. I don't use or know Docker, so please, don't ask me for help.
