+
+## Getting started
+
+### Run indexer vs goerli
+
+- install docker
+- `cp example.env .env`
+- fill in .env
+- run `docker-compose up` to start the indexer vs optimism goerli network
+
+### Run indexer with go
+
+See the flags in `flags.go` for reference of what command line flags to pass to `go run`
+
+### Run indexer vs devnet
+
+TODO add indexer to the optimism devnet compose file (previously removed for breaking CI)
+
+### Run indexer vs a custom configuration
+
+`docker-compose.dev.yml` is git ignored.   Fill in your own docker-compose file here.
