@@ -14,3 +14,21 @@ found in `crates/web-sys/Cargo.toml`, but the rule of thumb for `web-sys` is
 that each type has its own cargo feature (named after the type). Using an API
 requires enabling the features for all types used in the API, and APIs should
 mention in the documentation what features they require.
+
+## How to add an interface
+
+If you don't see a particular web API in `web-sys`, here is how to add it.
+
+1. Copy the WebIDL specification of the API and place it in a new file in the
+   `webidls/unstable` folder. You can often find the IDL by going to the MDN
+   docs page for the API, scrolling to the bottom, clicking the
+   "Specifications" link, and scrolling to the bottom of the specification
+   page. For example, the bottom of the [MDN
+   docs](https://developer.mozilla.org/en-US/docs/Web/API/MediaSession) on the
+   MediaSession API takes you to the
+   [spec](https://w3c.github.io/mediasession/#the-mediasession-interface). The
+   [very bottom](https://w3c.github.io/mediasession/#idl-index) of _that_ page
+   is the IDL.
+2. Run `cargo run --release --package wasm-bindgen-webidl -- webidls src/features`
+3. Copy the contents of `features` into the `[features]` section of `Cargo.toml`
+4. Run `git add .` to add all the generated files into git.
