 `@github/webauthn-json` is a client-side Javascript library that serves as convenience wrapper for the the [WebAuthn API](https://www.w3.org/TR/webauthn/) by encoding binary data using [base64url](https://w3c.github.io/webauthn/#sctn-dependencies) (also known as "websafe" or "urlsafe" base64).
 
-The WebAuthn API itself takes input and output values that look almost like JSON, except that binary data is represented as `ArrayBuffer`s. Using `webauthn-json` allows the data to be sent from/to the server as normal JSON without any custom client-side processing. This will be possible [directly in the browser](https://github.com/w3c/webauthn/issues/1683) some day, but we're here for you until then.
