+### Installation & Execution
+
+#### ControlBox
+
+Run ControlBox:
+```
+cd /path/to/controlbox
+go run . 4712
+2025-04-10 16:39:14 INFO  Local SKI: A46D9C217B8F335E921C4FAA087E615C9D2A73F0
+```
+
+Note the local SKI which is logged on ControlBox startup. Certificate and key are automatically created and saved to respective files.
+
+#### evcc
+
+As of evcc 0.301.0, EEBUS is enabled by default with certifacte/key being automatically created, dramatically simplifying setup.
+
+Add ControlBox to the `evcc.yaml`:
+```
+hems:
+  type: eebus
+  ski: A46D9C217B8F335E921C4FAA087E615C9D2A73F0 # local SKI of the ControlBox
+```
+
+Restarting evcc will automatically connect evcc to the ControlBox.
+
+#### ControlBox Frontend
+
+Install dependencies:
+```
+cd /path/to/controlbox/frontend
+npm install
+```
+
+Run web server:
+```
+npm run dev
+```
+
