-This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
+# Thoughts — Frontend
 
-## Getting Started
+Next.js 15 (App Router) frontend for the [Thoughts](../) self-hosted microblogging server.
 
-First, run the development server:
+## Features
+
+- Post thoughts, reply, boost, and like
+- Home feed, public feed, per-user timelines
+- Browse and follow remote Fediverse actors by `@user@instance` handle
+- Full remote actor profiles — bio, banner, profile fields, posts tab, followers/following tabs
+- Full-text search for local users and thoughts; remote actor lookup via WebFinger
+- Notifications, API key management, profile editing
+- Dark/light theme
+
+## Setup
 
 ```bash
-npm run dev
-# or
-yarn dev
-# or
-pnpm dev
-# or
-bun dev
+bun install
 ```
 
-Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+Copy `.env.local.example` to `.env.local` (or set the variables directly):
 
-You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+```env
+NEXT_PUBLIC_API_URL=http://localhost:8000
+NEXT_PUBLIC_SERVER_SIDE_API_URL=http://localhost:8000
+```
 
-This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
+`NEXT_PUBLIC_API_URL` is used by client-side fetches (runs in the browser).
+`NEXT_PUBLIC_SERVER_SIDE_API_URL` is used by server-side fetches (runs in Next.js SSR — can point to an internal service URL in Docker).
