-For the moment, the node runs a simple p2p broadcast. To run it you need to do
-the usual cargo things
+As a strategy to optimize the development workflow, you should use [mutinynet](https://mutinynet.com/) (a modified `signet` with 30s block time). You can
+start a local node via
+```
+cd mutinynet
+./run.sh
+cd ..
+```
+
+The node RPC will be available on `0.0.0.0:38332` with username `braidpooldev` and password `braidpooldev`.

+# Running the braidpool node
+
+For the moment, the braidpool node runs a simple p2p broadcast. 
+It also connects to a bitcoin RPC node to get new block templates.
 
+To run the braidpool node you need to do the usual cargo things:
 ```
 cd node
 cargo build
