 # headscale
-An opensource implementation of the Tailscale coordination server
+An open source implementation of the Tailscale coordination server.

+
+## Disclaimer
+
+1. I have nothing to do with Tailscale, or Tailscale Inc. Just a fan of their tech.
+2. The purpose of writing this was to learn a bit how Tailscale works. Hence the emojis in the log messages and other terrible code.
+3. I don't use Headscale myself (their Solo plan + DERP infra is way more convenient).
+4. Headscale adds all the machines under the same user. Be careful!
+
+
+## Running it
+
+1. Compile the headscale binary
+  ```
+  go build cmd/headscale/headscale.go 
+  ```
+  
+2. Get youself a PostgreSQL DB running. 
+
+  ``` 
+  docker run --name headscale -e POSTGRES_DB=headscale -e \
+    POSTGRES_USER=foo -e POSTGRES_PASSWORD=bar -p 5432:5432 -d postgres
+  ```
+
+3. Run it (asuming you have renamed the config.json.example to config.json)
+  ```
+  ./headcale
+  ```
+  
+4. Add your first machine
+  ```
+  tailscale up -login-server YOUR_HEADSCALE_URL
+  ```
