 ## Installation
+
 ```sh
 $ cargo add surf
 ```
 
 ## Safety
+
 This crate makes use of a single instance of `unsafe` in order to make the WASM
 backend work despite the `Send` bounds. This is safe because WASM targets
 currently have no access to threads. Once they do we'll be able to drop this
 implementation, and use a parked thread instead and move to full multi-threading
 in the process too.
