 ### Frontend development
 
 Install dependencies by running `pnpm i`. Then run `pnpm dev` to launch lemmy-ui locally. It automatically connects to the Lemmy backend on `localhost:8536`. Open [localhost:1234](http://localhost:1234) in your browser. The project is rebuilt automatically when you change any files.
