-```sh
-corepack enable

-
-Then, simply run the install command:

 ## Development
 
 Here are some helpful commands:
 
 ```sh
-# Build WXT package
-cd packages/wxt
-pnpm build
+# Build WXT package and workspace dependencies
+bun run --filter wxt build
 ```
 
 ```sh
-# Build WXT package, then build demo extension
