 Can save a few kilobytes if you don't need the metadata. "Safe" removes only metadata that
 will never affect rendering of the image. "All" removes all metadata that is not critical

+`-s` can be used as a shorthand for `--strip safe`.
 
 More advanced options can be found by running `oxipng -h`.
 
+## Library Usage
+
+Although intended to be used as an executable, oxipng can also be used as a library in
+other Rust projects. To do so, simply add oxipng as a dependency in your Cargo.toml,
+then `extern crate oxipng` in your project. You should then have access to all of the library
+functions [documented here](https://shssoichiro.github.io/oxipng/doc/oxipng/). The simplest
+method of usage involves creating an
+[Options struct](https://shssoichiro.github.io/oxipng/doc/oxipng/struct.Options.html) and
+passing it, along with an input filename, into the
+[optimize function](https://shssoichiro.github.io/oxipng/doc/oxipng/fn.optimize.html).
