+## Development (Forta specific)
+
+Edit `alerting-forta/<SUBMODULE>/forta.config.json` and set `jsonRpcUrl` to your JSON-RPC provider. Install deps:
+
+```
+yarn install
+```
+
+Running in a live mode:
+
+```
+yarn start:dev
+```
+
+Testing on a specific block/range/transaction:
+
+```
+yarn block 13626668
+yarn range '13626667..13626668'
+yarn tx 0x2d2774c04e3faf9f17cd26e0978bb812081b9d0b5cc6fd8bf04cc441f92c0a8c
