+### Using wp-now
+
+Alternatively, you can use [wp-now](https://github.com/WordPress/playground-tools/tree/trunk/packages/wp-now), a tool from the WordPress Playground team that makes it easy to run WordPress locally:
+
+```bash
+# Install wp-now globally
+npm install -g @wp-playground/wp-now
+
+# Start a WordPress instance with the current plugin
+wp-now start
+
+# Start with multisite enabled
+wp-now start --multisite
+
+# Start with specific PHP and WordPress versions
+wp-now start --php 8.0 --wp 6.2
+
+# Start with WP_DEBUG enabled
+wp-now start --wp-debug
+```
+
+This will start a local WordPress instance with your plugin installed and activated.
