 ### Requirements
 To build Nanoforge from source you'll need these programs:
-- [Visual Studio 2019 with C++ Cmake tools](https://visualstudio.microsoft.com/downloads/) - If you already installed VS2019 and didn't check the CMake option you can install it by clicking `Tools > Get Tools and Features`, then checking "C++ Cmake tools for Windows" in the Individual Components tab of the installer.
+- [Beeflang IDE (windows only)](https://www.beeflang.org/) - To compile the source code.
 - [Git](https://git-scm.com/) - For downloading dependencies.
 
 ### Steps
 1) Clone the repo with `git clone https://github.com/Moneyl/Nanoforge.git`
 2) `cd` into the directory you cloned the repo to then download the dependencies with `git submodule update --init --recursive`
-3) Open the project in VS2019 by right clicking the folder you cloned it in and selecting "Open in Visual Studio". Alternatively select the folder with `File > Open > Folder...` in VS2019.
-4) Build the project with `Build > Build Nanoforge.exe` (Ctrl + B). Make sure Nanoforge.exe is selected as the build target. The first time opening the project you might need to wait for CMake config to finish before the option becomes available. I recommend using the "x64-RelWithDebInfo" build option since it'll be optimized but still have some debug info so you can use the debugger. Nanoforge is very slow when built with the normal debug option.
-5) Once it's done building you can run it with the debugger attached using F5 or without using Ctrl + F5.
+3) Open the project in the Beef IDE via `File > Open > Open Workspace...`
+4) Build and run the project with F5.
