-## Send commands to bitcoind
+You can run tests on `MySql` database instead of `Postgres` by setting environnement variable `TESTS_DB` equals to `MySql`.
+
+## How to manually test payments
+
+### 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 exec -ti btcpayserver_dev_bitcoind bitcoin-cli -regtest -conf="/data/bitcoin.conf" -datadir="/data" sendtoaddress "mohu16LH66ptoWGEL1GtP6KHTBJYXMWhEf" 0.23111090
+./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. 
+
+### Using the test lightning-cli
+
+If you are using Linux:
+```
+./docker-customer-lightning-cli.sh pay lnbcrt100u1pd2e6uspp5ajnadvhazjrz55twd5k6yeg9u87wpw0q2fdr7g960yl5asv5fmnqdq9d3hkccqpxmedyrk0ehw5ueqx5e0r4qrrv74cewddfcvsxaawqz7634cmjj39sqwy5tvhz0hasktkk6t9pqfdh3edmf3z09zst5y7khv3rvxh8ctqqw6mwhh

+```
+
+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.
