 Use the following env vars to configure the lotus node that lily reads from, and the database that it writes to:
 
-- `LOTUS_PATH` - path to the lotus data dir. _default: `~/.lotus`_
-- `LOTUS_DB` - database connection . _default: `postgres://postgres:password@localhost:5432/postgres?sslmode=disable`_

+- `LILY_DB` - database connection . _default: `postgres://postgres:password@localhost:5432/postgres?sslmode=disable`_
 
 The `walk` and `watch` commands expect a list of tasks to be provided. Each task is responsible for reading a particular type of data from the chain and persisting it to the database.
