 Building on Windows is a bit of a tricky process. Here are some helpful tips.
 
-#### Nightly Compiler
-
-As a few crates require nightly features on Windows, a `rust-toolchain.toml` is provided
-to have rustup use the right compiler version.
-
-If for some reason this cannot be used or doesn't kick-in, one can also set an override.
-
-```shell
-rustup override add nightly-2024-07-01
-```
-
-If a stable nightly isn't desired or necessary, the latest nightly compiler can also be used:
-
-```shell
-rustup override add nightly
-```
-
 #### File permissions
 
 We use `pnpm`, which requires a relatively recent version of Node.js.
