 ## Prerequisite
 
-- A workstation to run headscale (could be Linux, macOS, other supported platforms)
+- A workstation to run `headscale` (any supported platform, e.g. Linux).
-- A headscale server (version `0.13.0` or newer)
+- A headscale server with gRPC enabled.
-- Access to create API keys (local access to the headscale server)
+- Connections to the gRPC port (default: `50443`) are allowed.
-- headscale _must_ be served over TLS/HTTPS
+- Remote access requires an encrypted connection via TLS.
-  - Remote access does _not_ support unencrypted traffic.
+- An API key to authenticate with the headscale server.
-- Port `50443` must be open in the firewall (or port overridden by `grpc_listen_addr` option)

 ## Troubleshooting
 
-Checklist:
+- Make sure you have the _same_ headscale version on your server and workstation.
-
+- Ensure that connections to the gRPC port are allowed.
-- Make sure you have the _same_ headscale version on your server and workstation
+- Verify that your TLS certificate is valid and trusted.
-- Make sure you use version `0.13.0` or newer.
+- If you don't have access to a trusted certificate (e.g. from Let's Encrypt), either:
-- Verify that your TLS certificate is valid and trusted
+    - Add your self-signed certificate to the trust store of your OS _or_
-  - If you do not have access to a trusted certificate (e.g. from Let's Encrypt), 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
-  - Set `HEADSCALE_CLI_INSECURE` to 0 in your environment
+      `HEADSCALE_CLI_INSECURE=1` via an environment variable. We do **not** recommend to disable certificate validation.
