 # Requirements
 
-- A desktop platform which can compile .NET 4.5.
-- Visual Studio or MonoDevelop is recommended.
+- A desktop platform which can compile .NET 4.5 (tested on macOS, linux and windows). We recommend using [Visual Studio Code](https://code.visualstudio.com/) (all platforms) or [Visual Studio Community Edition](https://www.visualstudio.com/) (windows only), both of which are free.
+- Make sure you initialise and keep submodules up-to-date.
 
 # Contributing
 
 We welcome all contributions, but keep in mind that we already have a lot of the UI designed. If you wish to work on something with the intention on having it included in the official distribution, please open an issue for discussion and we will give you what you need from a design perspective to proceed. If you want to make *changes* to the design, we recommend you open an issue with your intentions before spending too much time, to ensure no effort is wasted.
