-## Setup on WSL2
-::: warning For WSL2 users
-Please refer to the [**Setup on Linux**](#setup-on-linux-macos-wsl2) instructions; setting up on WSL2 is identical to setting up on Linux.
-
-However, it's important to note a significant performance loss impacting benchmarks and leading to a suboptimal development experience. For this coursework, we recommend using native Windows instead of WSL2.
-
-If you opt for WSL2 development, **ensure your workspace is located within the WSL2 file system**.
