 ## Imports
 
-Our imports used to be a mess before we tamed the chaos with these rules.
+Our imports used to be a mess before we tamed the chaos with a formatting rule that has to be applied manually, since `rustfmt` doesn't support it.
 
-At the top of Rust files, use the convention of separating imports into three blocks, ordered as:
-1. Local (`use super::` and `use crate::`)
-2. First-party crates (e.g. `use editor::` or `bezier_rs::`)
-3. Third-party libraries (e.g. `use std::` or `use glam::`)
