-`ByteSize` is a utility for human-readable byte count representations.
+<!-- prettier-ignore-end -->
+
+<!-- cargo-rdme start -->
+
+`ByteSize` is a semantic wrapper for byte count representations.
 
 Features:
 
-- Pre-defined constants for various size units (e.g., B, KB, KiB, MB, MiB, GB, GiB, ... PiB).
+- Pre-defined constants for various size units (e.g., B, Kb, Kib, Mb, Mib, Gb, Gib, ... PB).
 - `ByteSize` type which presents size units convertible to different size units.
 - Arithmetic operations for `ByteSize`.
-- FromStr impl for `ByteSize`, allowing to parse from string size representations like 1.5KiB and 521TiB.
+- `FromStr` impl for `ByteSize`, allowing for parsing string size representations like "1.5KiB" and "521TiB".
 - Serde support for binary and human-readable deserializers like JSON.

-## Example
-
-### Human readable representations (SI unit and Binary unit)
+Construction using SI or IEC helpers.

-### Arithmetic operations
+Display as human-readable string.
 
 ```rust
 use bytesize::ByteSize;
 
-fn byte_arithmetic_operator() {
-    let x = ByteSize::mb(1);
-    let y = ByteSize::kb(100);
+assert_eq!("482.4 GiB", ByteSize::gb(518).to_string_as(true));
+assert_eq!("518.0 GB", ByteSize::gb(518).to_string_as(false));
+```
+
+Arithmetic operations are supported.
+
+```rust
+use bytesize::ByteSize;
 
-    let plus = x + y;
-    println!("{}", plus);
+let plus = ByteSize::mb(1) + ByteSize::kb(100);
+println!("{plus}");

-    println!("{}", minus);
-}
+let minus = ByteSize::tb(1) - ByteSize::gb(4);
+assert_eq!(ByteSize::gb(996), minus);
