 # Controlling headscale with remote CLI
 
-This documentation has the goal of showing a user how-to control a headscale instance
+This documentation has the goal of showing a user how-to set control a headscale instance
 from a remote machine with the `headscale` command line binary.
 
 ## Prerequisite
 
-- A workstation to run `headscale` (any supported platform, e.g. Linux).
-- A headscale server with gRPC enabled.
-- Connections to the gRPC port (default: `50443`) are allowed.
-- Remote access requires an encrypted connection via TLS.
-- An API key to authenticate with the headscale server.
+- A workstation to run headscale (could be Linux, macOS, other supported platforms)
+- A headscale server (version `0.13.0` or newer)
+- Access to create API keys (local access to the headscale server)
+- headscale _must_ be served over TLS/HTTPS
+  - Remote access does _not_ support unencrypted traffic.
+- Port `50443` must be open in the firewall (or port overridden by `grpc_listen_addr` option)
 
 ## Create an API key
 
-We need to create an API key to authenticate with the remote headscale server when using it from our workstation.

 ## Troubleshooting
 
-- Make sure you have the _same_ headscale version on your server and workstation.
-- Ensure that connections to the gRPC port are allowed.
-- Verify that your TLS certificate is valid and trusted.
-- If you don't have access to a trusted certificate (e.g. from Let's Encrypt), either:
-    - Add your self-signed certificate to the trust store of your OS _or_
-    - Disable certificate verification by either setting `cli.insecure: true` in the configuration file or by setting
-      `HEADSCALE_CLI_INSECURE=1` via an environment variable. We do **not** recommend to disable certificate validation.
+Checklist:
+
+- Make sure you have the _same_ headscale version on your server and workstation
+- Make sure you use version `0.13.0` or newer.
+- Verify that your TLS certificate is valid and trusted
