+# Cwtch Server
+
+## Running
+
+- cd app
+- go build
+- ./app
+
+The app takes the following arguments
+- -debug: enabled debug logging
+
+The app takes the following environment variables
+- CWTCH_HOME: sets the config dir for the app
+
+## Using the Server
+
+When run the app will output standard log lines, one of which will contain the `tofubundle` in purple. This is the part you need to capture and import into a Cwtch client app so you can use the server for hosting groups
+
+## Docker
+
+Currently, the dockerfile is out of date and is not usable. Check back for updates.
