+## Flagsmith with Remix
+
+- 📖 [Flagsmith docs](https://docs.flagsmith.com)
+- 📖 [Remix docs](https://remix.run/docs)
+
+## Prerequsities
+
+- Rename `.env.test` file to `.env`
+- Update `FLAGSMITH_ENVIRONMENT_ID` variable with your environment ID
+- Check the `routes/_index.tsx` file to see the usage
+
+**Note:** The example is using `test_feature` feature flag with a value. If you want to test the repository as it is, then please make sure that you have created a feature flag with the same name through your Flagsmith Dashboard for the environment you are testing for.
+
+## Development
+
+Run the dev server:
+
+```shellscript
+npm run dev
+```
+
+## Deployment
+
+First, build your app for production:
+
+```sh
+npm run build
+```
+
+Then run the app in production mode:
+
+```sh
+npm start
+```
+
