 ### Formatting
 
 - All Rust code should be formatted using `rustfmt`
+- Imports in Rust source files are to be merged into a single `use` block. For example, instead of:
+  ```rust
+  use devtimer::SimpleTimer;
+  use devtimer::ComplexTimer;
+  use serde::{Serialize, Deserialize};
+  use crate::something;
+  ```
+  this mode of styling is preferred:
