+# Contributing to DecapStream
+
+## Running locally
+
+```bash
+npm install
+npm run dev
+```
+
+In dev mode, all `supervisorctl` and `captureThumb` calls are mocked with console logs — no Supervisord or ffmpeg required.
+
+## Before submitting a PR
+
+- Run `npm run lint` and fix any errors
+- Run `npx tsc --noEmit` if you changed types, interfaces, or added imports
+- Keep changes focused — one concern per PR
+
+## What's welcome
+
+- Bug fixes
+- Documentation improvements
+- New stream configuration options
+- UI improvements
+
+## What to discuss first
+
+For larger changes (new architecture, new dependencies, significant behavior changes), open an issue first to align on the approach before investing time in implementation.
+
+## Stack
+
+- Next.js 15 + TypeScript + Tailwind CSS v4
+- Flat file persistence (`streams.json`) — no database
+- Supervisord for process management (mocked in dev)

 Turn any web page into an RTMP/HLS stream. Chromium renders the page, ffmpeg captures it, MediaMTX publishes it. Built for NOC environments and digital signage.
