-### Caveat: Architecture
+### Docker Compose
+
+**You need to edit the `ZT_NETWORKS` and `ARCH` variable in the `docker-compose.yml` file first to add your networks and make sure your acrhitecture is correct (see [this page](http://download.zerotier.com/debian/buster/pool/main/z/zerotier-one/) for examples, usually either amd64 or arm64)**
+
+Easy one-liner for Docker Compose:
+
+`docker-compose build && docker-compose up -d`
+
+If you want to disable bridging, set `ZT_BRIDGE=false`. This can be done after the initial networks have been joined (just rebuild the container), as the ZeroTier config persists but IPTables forwarding is done on each container startup.
+
+### OG Docker
+
+`docker build -t zerotierbridge .`
+
+`docker run --privileged -e ZT_NETWORKS=NETWORK_ID_HERE -e ZT_BRIDGE=true zerotierbridge:latest`
+
+Add your network ID(s) into the `ZT_NETWORKS` argument, space separated.
+
+Disable bridging by passing `ZT_BRIDGE=false`. This can be done after the initial networks have been joined (just rebuild the container), as the ZeroTier config persists but IPTables forwarding is done on each container startup.
+
+#### Persistent Storage
+
+If you would like the container to retain the same ZeroTier client ID on reboot, attach a volume as per the below.
+
+`docker run --privileged -e ZT_NETWORKS=NETWORK_ID_HERE ZT_BRIDGE=true --volume zt1:/var/lib/zerotier-one/ zerotierbridge:latest`
