+
+### Using the test bitcoin-cli
+
+You can call bitcoin-cli inside the container with `docker exec`, for example, if you want to send `0.23111090` to `mohu16LH66ptoWGEL1GtP6KHTBJYXMWhEf`:
+```
+./docker-bitcoin-cli.sh sendtoaddress "mohu16LH66ptoWGEL1GtP6KHTBJYXMWhEf" 0.23111090
+```
+
+If you are using Powershell:
+```
+.\docker-bitcoin-cli.ps1 sendtoaddress "mohu16LH66ptoWGEL1GtP6KHTBJYXMWhEf" 0.23111090
+```
+
+### Using the test litecoin-cli
+
+Same as bitcoin-cli, but with `.\docker-litecoin-cli.ps1` and `.\docker-litecoin-cli.sh` instead.

+If you get this message:
+
+```
+{ "code" : 205, "message" : "Could not find a route", "data" : { "getroute_tries" : 1, "sendpay_tries" : 0 } }
+```
+
+Please, run the test `CanSetLightningServer`, this will establish a channel between the customer and the merchant, then, retry.
+
+## FAQ
+
+`docker-compose up dev` failed or tests are not passing, what should I do?
+
+1. Run `docker-compose down --v` (this will reset your test environment)
+2. Run `docker-compose pull` (this will ensure you have the lastest images)
+3. Run again with `docker-compose up dev`
+
+If you still have issues, try to restart docker.
