+# Local docker registry
+
+You can host your own docker registry that can be used to transmit images to a drone over a local network.
+To start the regisry, spin up the compose session in this folder.
+The registry is going to be insecure without a proper SSL certificate, therefore, the client needs to treat it in a special way.
+Add the following line to `/etc/docker/daemon.json` in the client host operating system to allow pulling from your local registry:
+
+```json
+
+```
