-Docker Compose Example
+# GeyserDockerBuilder
+
+Jenkins pipeline to build a Docker image of Geyser Standalone.
+
+```bash
+build.sh    # the old pipeline script, not used anymore
+Dockerfile  # used to build the image
+Jenkinsfile # the new pipeline script
+Readme.md   # you are reading this file
+run.sh      # entrypoint of the docker image
+```
+
+## Pipeline process
+
+- Fetches the information about the latest build of Geyser (version, build number), from the [GeyserMC API](https://download.geysermc.org/v2/projects)
+- Downloads the Geyser Standalone jar file.
+- Builds the docker image with the downloaded jar and the entrypoint script.
+- Pushes the image to the container registry with the tags `latest` and `$geyser_version-$geyser_build` (e.g. `2.2.0-408`)
+
+## Docker Compose Example
 
 ```yml
 version: "3"
 services:
-  (server-name):
-    image: "cr.pandacube.fr/geyser:(version)"
+  geyser:
+    image: "cr.pandacube.fr/geyser:latest"
     stdin_open: true # docker run -i
     tty: true        # docker run -t
     user: "1000:1000" # uid and gid of owner of working dir
