 # Thoughts
 
+A self-hosted microblogging server with full ActivityPub federation. Write short posts, follow people on Mastodon and other Fediverse servers, and receive their posts in your feed. Built in Rust with a Next.js frontend.
+
 **Tagline:** Your Space, Your Friends, Your Feed.
 
-Thoughts is a decentralized social media platform focused on genuine user connection and creative self-expression. It is a deliberate departure from algorithm-driven feeds and corporate-controlled online spaces — a digital "third place" reminiscent of the early internet.
+## Features
+
+- Short-form posts ("thoughts") with replies, boosts, and likes
+- Full ActivityPub federation — follow/unfollow remote actors, accept/reject followers, federated content broadcast as `Note` objects, paginated outbox, NodeInfo discovery, WebFinger, shared inbox, actor profile sync
+- **Remote actor discovery** — search by `@user@instance` handle, view full remote profiles (bio, banner, profile fields, posts, followers, following tabs), follow from within the UI
+- **Worker-backed remote caches** — remote posts and follower/following lists are fetched by the NATS worker and cached locally; profiles populate on first visit and refresh in the background
+- Content negotiation at `GET /users/{username}` — serves ActivityPub actor JSON or REST profile based on `Accept` header
+- Federation moderation — per-instance domain blocking, per-user actor blocking with `Block` activity delivery
+- Async event fan-out via NATS JetStream — notifications and AP delivery run in a separate worker process
+- JWT authentication (Bearer token) and long-lived API keys
+- OpenAPI docs at `/docs` (Swagger UI) and `/scalar` (Scalar)
+- Full-text search over thoughts and users via PostgreSQL trigram indexes
+- Top friends — pin up to 5 users as highlighted contacts
+- Home feed, public feed, and per-user thought timelines
+- Notifications

 | Chronological Above All | The main feed is always reverse-chronological. No algorithmic sorting. |
 | User in Control | Users decide what they see by choosing who to follow. No suggestions. |
 | Radical Self-Expression | Profiles support custom CSS for full personalization. |

 | API-First Design | The backend is the core service; the frontend is just the first client. |
