+# Deployment using Docker
+
+Using Docker is the most easy and recommended way to run PsiTransfer. There is an 
+[official Container](https://hub.docker.com/r/psitrax/psitransfer/) which is 
+updated whenever a GitHub push occurs.
+
+```bash
+docker run -d -v $PWD/data:/data -p 3000:3000 psitrax/psitransfer
+```
+The above command starts the PsiTransfer Docker container and 
+ * `-d` puts the process into background (daemon mode)
+ * `-v` mounts the data volume into the container
+ * `-p` forwards the traffic from port 3000 into the container
+
+**Protipp**: There are several [container tags](https://hub.docker.com/r/psitrax/psitransfer/tags/)
+if you want to use a specific version. E.g. `1` is always the latest stable `1.x.x` and `1.1`
+correlates with `1.1.x`.
+
+If you want to customize some PsiTransfer configurations use environment parameters
+by adding `-e` flags to the `docker run` command.
+
+```bash
+docker run -v $PWD/data:/data -p 3000:8080 \
+  -e PSITRANSFER_PORT=8080 \
+  -e PSITRANSFER_DEFAULTRETENTION=3600 \
+  psitrax/psitransfer
+```
+
+**Protipp**: By adding `--restart always` Docker will autostart the container after reboots.
