+# Lab signal bot
+
+## Starting
+
+### Configuration
+
+Create a config:
+```
+cp config.json.example config.json
+vi config.json
+```
+
+(Inside the docker container, "http://signal-cli-rest-api:8080" can be resolved to the host of the other docker container. Outside not.)
+
+### Link the signal-cli bot
+
+Start containers:
+
+```
+docker compose up -d
+```
+
+In the beginning, this will only start the `signal-cli-rest-api` docker container. The other container will fail, since the `signal-cli` is not linked to the account. If you already activated the phone number with another signal device, you can register the new device.
+
+Join the docker do this:
+```
+docker exec -it lab-signal-bot-signal-cli-rest-api-1 /bin/bash
+```
+
+Change user:
+```
+su signal-api
+```
+
+Link the new device:
+```
+signal-cli --config /home/.local/share/signal-cli link
+```
+
+Exit the docker shell.
+
+Restart docker container:
+```
+docker restart lab-signal-bot-signal-cli-rest-api-1
+```
+
+From host, list signal groups:
+```
+python list_signal_groups.py --api-url http://localhost:8080/ -i
+```
+
+Now, you can set the identifier of the group you want in the config.json:
+```
+vi config.json
+```
+
+Rebuild containers:
+```
+docker compose up --build -d
+```
