 If/when fif hits version 1.0, these rules will likely remain the same as they are now.
 
+## Code style
+fif is formatted with `rustfmt` using a nightly toolchain, specifically with the command `cargo +nightly fmt`. Tabs are
+used for indentation, and are assumed to be two spaces wide. Lines are 120 characters wide. Braces are placed on the 
+same line (["OTBS"](https://en.wikipedia.org/wiki/Indentation_style#Variant:_1TBS_(OTBS)) format), except in the case of
+`where` clauses in generic parameters.
+
+For more detailed information on the formatting rules used by this project, see the configured options in
+[`rustfmt.toml`](https://gitlab.com/Lynnesbian/fif/-/blob/master/rustfmt.toml).
