Copy the `.env-sample` file into `.env` and check the environmental variables are right for your development.
### (optional, if error) Install LND python dependencies
Depending on your system your dev setup might already be good to start working. However, it might happen that when mounting "." into "/src/usr/robosats" in the docker-compose.yml, it deletes the lnd grpc files that where previously generated during the docker build. If this is the case, run the following:
```
cd api/lightning
pip install grpcio grpcio-tools googleapis-common-protos
git clone https://github.com/googleapis/googleapis.git
curl -o lightning.proto -s https://raw.githubusercontent.com/lightningnetwork/lnd/master/lnrpc/lightning.proto
python3 -m grpc_tools.protoc --proto_path=googleapis:. --python_out=. --grpc_python_out=. lightning.proto
```
We also use the *Invoices* and *Router* subservices for invoice validation and payment routing.
```
curl -o invoices.proto -s https://raw.githubusercontent.com/lightningnetwork/lnd/master/lnrpc/invoicesrpc/invoices.proto
python3 -m grpc_tools.protoc --proto_path=googleapis:. --python_out=. --grpc_python_out=. invoices.proto
curl -o router.proto -s https://raw.githubusercontent.com/lightningnetwork/lnd/master/lnrpc/routerrpc/router.proto
python3 -m grpc_tools.protoc --proto_path=googleapis:. --python_out=. --grpc_python_out=. router.proto
```
Generated files can be automatically patched for relative imports like this:
```
sed -i 's/^import .*_pb2 as/from . \0/' api/lightning/router_pb2.py
