 `make start-feature-backend` will inject the `perses-dashboards`, `incidents`, and `dev-config` features by default. Features such as `acm-alerting` which take in extra parameters will need to run the `make start-feature-backend` command with the appropriate environment variables, such as `MONITORING_PLUGIN_ALERTMANAGER`.

+#### Local Development with Perses Proxy 
+The bridge script `start-console.sh` is configured to proxy to a local Perses instance running at port `:8080`. To run the local Perses instance you will need to clone the [perses/perses](https://github.com/perses/perses) repository and follow the start up instructions in [ui/README.md](https://github.com/perses/perses/blob/63601751674403f626d1dea3dec168bdad0ef1c7/ui/README.md) :

+```
+# Clone the perses/perses repo 
+$ git clone https://github.com/perses/perses.git
+$ cd perses
+
+# Follow the instructions in ui/README.md
+$ cd ui 
+$ npm install 
+$ npm run build
+$ ./scripts/api_backend_dev.sh
+
+# Lastly navigate to http://localhost:8080/ to see Perses app running
