 ## tiny-png
 
-Tiny Rust PNG decoder.
+Tiny Rust PNG decoder with no dependencies (not even `std` or `alloc`).
 
-This decoder can be used without `std` or `alloc` by disabling the `std` feature (enabled by default).

 ## Features
 
-- `std` (default: enabled) — use standard library. enabling it allows you to read from `BufReader<File>` but
-   adds `std` as a dependency.
 - `adler` (default: disabled) — check Adler-32 checksums. slightly increases code size and
   slightly decreases performance but verifies integrity of PNG files.
