+# Docker Installation
+
+> [!WARNING]  
+> The Docker deployment method is currently unmaintained and may not work as expected. Help is wanted! If you are a Docker enjoyer, please consider contributing to this deployment method.
+
+1. Pull the Docker image:
+
+```ssh
+docker pull ghcr.io/shocknet/lightning-pub:latest
+```
+
+2. Run the Docker container:
+
+```ssh
+docker run -d \
+  --name lightning-pub \
+  --network host \
+  -p 1776:1776 \
+  -p 1777:1777 \
+  -v /path/to/local/data:/app/data \
+  -v $HOME/.lnd:/root/.lnd \
+  ghcr.io/shocknet/lightning-pub:latest
+```
+Network host is used so the service can reach a local LND via localhost. LND is assumed to be under the users home folder, update this location as needed.
