 ### Development
 
+1. All development is subject to our [PHP package development guidelines](https://github.com/DataLinx/php-package-template/blob/bc39ae340e7818614ae2aaa607e97088318dd754/docs/Documentation.md).
+2. Our [Filament app development docs](https://github.com/DataLinx/eclipsephp-core/blob/cae7143c8f745f142bba2bb4cf1483cf09401509/docs/Documentation.md) will also be helpful.

 #### Requirements
 * Linux, Mac or Windows with WSL
 * [Lando](https://lando.dev/) (optional, but easier to start with)
 
 #### Get started
 1. Clone the git repo
 2. Start the Lando container
-```shell
-  lando start
-````
+    ```shell
+    lando start
+    ````
 3. Install dependencies (this also runs the setup composer script)
-```shell
-  lando composer install
-````
-4. Happy coding 😉
+    ```shell
+    lando composer install
+    ````
+4. You can now develop and run tests. Happy coding 😉
+
+💡 To manually test the plugin in the browser, see our [recommendation](https://github.com/DataLinx/eclipsephp-core/blob/main/docs/Documentation.md#-plugin-development), which is also [how Filament suggests package development](https://filamentphp.com/docs/3.x/support/contributing#developing-with-a-local-copy-of-filament).  
+However, the plugin should be universal and not dependent on our app setup or core package.
