instructions.md

1. add dev.Dockerfile to /lnd
2. add entrypoint.sh to /lnd/docker
3. pick random itest in /lnd/itest to modify
4. in entrypoint.sh, replace make itest with make itest icase=$NAME_OF_ITEST_SNAKE_CASE;
5. run the shits

docker-compose build && docker-compose run --entrypoint "bash ./docker/entrypoint.sh" lnd

Do all this for setting up your nodes: https://github.com/lightningnetwork/lnd/blob/2efe5d527bfdb2c5c2c569bf507e957281548c5b/lntest/itest/lnd_misc_test.go#L1280

Use this lnrpc thing for your rpc calls https://github.com/lightningnetwork/lnd/blob/2efe5d527bfdb2c5c2c569bf507e957281548c5b/lntest/itest/lnd_misc_test.go#L1328
