2. The downloaded plugin will have react-wp-admin folder name. Rename it to your plugin name, also rename the file react-wp-admin.php to match your folder name.

3. Change the plugin information (in react-wp-admin.php) according to your needs.

4. Go to admin/react directory and install dependencies by running yarn.

5. Build commands

• yarn build - Production build
• yarn build:dev - Development build, generates sourcemaps
• yarn watch - Automatically runs yarn build:dev when files change

Do not modify anything outside src in react folder if you are not confident.
