 ## Usage
 
-In `substreams`:
+Run the `substreams-codegen` backend:
 
 ```bash
-cd devel/inittests
-go install -v ../../cmd/substreams && substreams init --generator ethereum_init_v1
+# remove the DEBUG var if you want info level logs
+DEBUG=.* go run ./cmd/substreams-codegen api --http-listen-addr "*:9000"
 ```
 
-In `substreams-codegen`:
+(Optionally) Run the remotebuild server locally:
 
 ```bash
-DEBUG=* go install -v ./cmd/substreams-codegen && substreams-codegen api --http-listen-addr "*:9000"
+GENERATOR_KEEP_FILES=true go run -v ./cmd/remotebuild
 ```
 
-In `substreams-codegen`:
+Use the `substreams` cli to initialize your Substreams.
 
 ```bash
-GENERATOR_KEEP_FILES=true go run -v ./cmd/remotebuild
+substreams init --discovery-endpoint http://localhost:9000
 ```

   - This _state_ is what gets serialized to JSON and sent to the client. It must be a usable interface, so pick your names wisely.
-  - Anything that is exported will be shared with the client, and come back during hydration (if a connection gets interrupted, or the user kept its `generator.json` state, and wants to simply rebuild).

+- It has an `Update()` method that is registered into the `loop.EventLoop` by the `codegen` framework.
   - This function can mutate state, and it is the only method who can mutate state.
   - This function follows the ELM paradigm, and must never do long-running operations, only quick routing.
   - A `NextStep()` function will choose where to go based on the current state, and continue the conversation to make sure it is valid and completely filled in.
