# you have two possible ways how to specify MACAROON_FILE and TLS_CERT_FILE
# 1. specify LND_HOME if it is located on your local machine, we derive default paths from there
# 2. specify env variables MACAROON_FILE and TLS_CERT_FILE

# also you want to specify LND_GRPC_HOST if your node is remote
# other config tweaks have to be done by changing lntop/home/initial-config-template.toml before build
# or ./_volumes/lntop-data/config-template.toml if you want to just an ad-hoc tweak of existing container

# note: docker uses network_mode: host
