+## Laravel Forge
+
+To install `excimer` on Laravel Forge, you need to SSH into your server and run:
+
+```bash
+sudo pecl install excimer
+```
+
+Afterwards you need to add the extension to your `php.ini` for Forge to pick up.
+Navigate to your server in Forge.
+Go to PHP -> click on the ... (of the version that is running) -> e.g. Edit PHP 8.3 FPM Configuration
+
+Navigate to the extension section and add: 
+
+```bash
+extension=excimer.so
+```
+
+Then you should be good to go and excimer should run when you configure a profiling sample rate.
