+##### Environment variables
+You can export the following environment variables for hastic-server to use:
+- HASTIC_API_KEY - (required) API-key of your Grafana instance
+- HASTIC_PORT - (optional) port you want to run server on, default: 8000

 ```bash
-export HASTIC_API_KEY=<your_grafana_api_key>
-export HASTIC_PORT=<port_you_want_to_run_server_on>
+export HASTIC_API_KEY=eyJrIjoiVjZqMHY0dHk4UEE3eEN4MzgzRnd2aURlMWlIdXdHNW4iLCJuIjoiaGFzdGljIiwiaWQiOjF9
