 If a 3rd party's crate/functions/types are small enough, it could be moved here to trim dependencies and allow easy modifications.
 
 ## Features
-Code can be selectively used/compiled with cargo's `--feature` or `features = ["..."]`.
+Modules can be selectively used/compiled with cargo's `--feature` or `features = ["..."]`.
 
-All features on by default.
+All features are off by default.
 
 See [`Cargo.toml`](Cargo.toml)'s `[features]` table to see what features there are and what they enable.
 
+Special non-module related features:
+- `serde`: Enables serde implementations on applicable types
+- `std`: Enables usage of `std`
+
 ## `#[no_std]`
 Each modules documents whether it requires `std` or not.
