+    ## Overview
+
+    The Audius API provides REST access to the world's largest open music catalog, built on the [Open Audio Protocol](https://openaudio.org). Use it to query and stream tracks, users, playlists, and more—perfect for building music players, discovery apps, and audio-native products.
+
+    ## Key Capabilities
+
+    - **Users** — Profiles, followers, following, search
+    - **Tracks** — Search, trending, stream, favorites, reposts
+    - **Playlists** — Create, update, browse, curate
+    - **Resolve** — Look up content by Audius canonical URLs (e.g. `audius.co/artist/...`)
+    - **Explore** — Trending content, charts, discovery
+    - **Comments, Tips, Rewards** — Social features and engagement
+
+    ## Authentication
+
+    - **Read-only** — Most endpoints work without credentials. Use an API key for higher rate limits.
+    - **Writes** — Upload, favorite, repost, and other mutations require an API key and secret. Get keys at [api.audius.co/plans](https://api.audius.co/plans) or [audius.co/settings](https://audius.co/settings).
