+# AFFiNE Electron App
+
+## Development
+
+To run AFFiNE Desktop Client Application locally, run the following commands:
+
+```sh
+# in repo root
+yarn install
+yarn workspace @affine/native build
+yarn dev
+
+# in packages/frontend/apps/electron
+yarn generate-assets
+yarn dev # or yarn prod for production build
+```
+
+## Troubleshooting
+
+If you have trouble building electron during `yarn install`, try setting mirror environment variable:
+
+```sh
+export ELECTRON_MIRROR="https://registry.npmmirror.com/-/binary/electron/"
+```
