+The library can be compiled to WebAssembly. You will need wasm-pack (`cargo install wasm-pack`) and can then build the library with `wasm-pack build --target web`. This generates a `pkg` folder which can be used in web environments.
+
 ## Capabilities
 The schmfication capabilities are able to preserve text case and any non-alphabetical characters.
 If a non-alphabetical character is between two alphabetical strings, both of the alphabetical strings will be interpreted as completely separate words.
 
-For example, the HTML code `<span>Entry<br></span>` will be converted into `<schman>Schmentry<schmer></schman>`.
