+## Troubleshooting
+
+### Reasons for alerts at startup
+
+PHP Monitor performs some integrity checks to ensure a good experience when using the app. You'll get a message telling you that PHP Monitor won't work correctly in the following scenarios:
+
+- The PHP binary is not located in `/usr/local/bin/php`
+- PHP 7.4 is missing in `/usr/local/opt`
+- Laravel Valet is missing in `/usr/local/bin/valet`
+- Brew has not been added to sudoers in `/private/etc/sudoers.d/brew`
+- Valet has not been added to sudoers in `/private/etc/sudoers.d/valet`
+
+Follow instructions as specified in the alert in order to resolve any issues.
+
+### Still seeing another PHP version (from before switching versions)?
+
+If you're still seeing an old version of PHP in your scripts — e.g. when running `phpinfo()` — I recommend you shut down the PHP service by running: 
+
+    sudo brew services stop php
+
+Please note that PHP Monitor will not be able to stop this service (it doesn't run as an administrator), so you'll need to handle this yourself.
+
+You should only have to do this **once**, and then PHP Monitor should work as usual.
