 #### Note on connecting to a local CHT instance
 
-When using `cht-conf` within a Docker container to connect to a CHT instance that is running on your local machine (e.g. a development instance), you cannot use the `--local` flag or `localhost` in your `--url` parameter (since these will be interpreted as "local to the container").

 It is recommended to run a local CHT instance using the [CHT Docker Helper script](https://docs.communityhealthtoolkit.org/apps/guides/hosting/4.x/app-developer/). You can connect to the resulting `...my.local-ip.co` URL from the Docker container (or the VS Code terminal). (Just make sure the port your CHT instance is hosted on is not blocked by your firewall). 
 
 ## Bash completion
 
 To enable tab completion in bash, add the following to your `.bashrc`/`.bash_profile`:
 
-	eval "$(cht-conf --shell-completion=bash)"
+	eval "$(cht --shell-completion=bash)"
