+# Contributing to Archipelago
+
+Thank you for your interest in contributing to Archipelago! This document covers the process for contributing code, reporting bugs, and submitting apps.
+
+## Code of Conduct
+
+Be respectful. We follow the [Contributor Covenant](https://www.contributor-covenant.org/version/2/1/code_of_conduct/).
+
+## Getting Started
+
+1. Fork the repository
+2. Clone your fork: `git clone https://github.com/YOUR_USERNAME/archy.git`
+3. Set up the dev environment (see `docs/development-setup.md`)
+4. Create a feature branch: `git checkout -b feature/your-feature`
+
+## Development Setup
+
+### Frontend (Vue.js)
+
+```bash
+cd neode-ui
+npm install
+npm start          # Dev server on :8100
+npm run type-check # TypeScript validation
+npm run build      # Production build
+npm test           # Run tests
+```
+
+### Backend (Rust)
+
+Build on a Linux server (Debian 12), **not** macOS:
+
+```bash
+cargo clippy --all-targets --all-features
+cargo fmt --all
+cargo test --all-features
+```
+
+### Deploy to dev server
+
+```bash
+./scripts/deploy-to-target.sh --live
+```
+
+## Code Style
+
+### Frontend (TypeScript + Vue)
+
+- `<script setup lang="ts">` — always Composition API
+- TypeScript strict mode — no `any`, use `unknown` or proper types
+- Global CSS classes in `src/style.css` — never inline Tailwind in components
+- Pinia for state management — focused single-purpose stores
+- Use `@/api/rpc-client.ts` for RPC calls
+
+### Backend (Rust)
+
+- No `unwrap()` or `expect()` in production code — use `?` operator
+- `thiserror` for library errors, `anyhow` for application errors
+- `tracing` for structured logging — never `println!`
+- Run `cargo clippy` and `cargo fmt` before commits
+
+### General
+
+- Functions under 50 lines, single responsibility
+- Comment WHY not WHAT
+- Remove dead code — never comment it out
+- No `TODO`/`FIXME` in commits
+
+## Commit Format
+
+```
+type: description
+```
+
+**Types**: `feat:`, `fix:`, `docs:`, `refactor:`, `test:`, `chore:`, `perf:`
+
+Examples:
+- `feat: add backup scheduling to settings page`
+- `fix: handle WiFi connection timeout gracefully`
+- `test: add unit tests for RPC client retry logic`
+
+## Pull Request Process
+
+1. Ensure your branch is up to date with `main`
+2. All checks must pass: TypeScript, build, tests, clippy
+3. Include a clear description of what changed and why
+4. Link any related issues
+5. Request review from a maintainer
+
+### PR Checklist
+
+- [ ] TypeScript type-check passes (`npm run type-check`)
+- [ ] Frontend builds (`npm run build`)
+- [ ] Tests pass (`npm test`)
+- [ ] Rust clippy clean (`cargo clippy --all-targets --all-features`)
+- [ ] No new compiler warnings
+- [ ] Follows code style guidelines above
+
+## Testing Requirements
+
+- New features need tests
+- Bug fixes need a regression test
+- Frontend: Vitest + Vue Test Utils
+- Backend: `#[test]` and `#[tokio::test]`
+- Target: maintain or improve existing coverage
+
+## Reporting Bugs
+
+Use the **Bug Report** issue template. Include:
+
+1. Steps to reproduce
+2. Expected behavior
+3. Actual behavior
+4. System info (hardware, OS version, Archipelago version)
+5. Screenshots if applicable
+6. Relevant logs (`journalctl -u archipelago`)
+
+## Feature Requests
+
+Use the **Feature Request** issue template. Include:
+
+1. Problem description
+2. Proposed solution
+3. Alternatives considered
+4. Impact on existing users
+
+## App Submissions
+
+To submit an app for the Archipelago marketplace:
+
+1. Create a manifest following `docs/app-manifest-spec.md`
+2. Ensure the container image is published to a public registry
+3. Test on Archipelago hardware (x86_64 and ARM64 if possible)
+4. Open a PR adding the app to the curated list
+5. Include: app description, icon, resource requirements, dependencies
+
+### App Requirements
+
+- Container must run as non-root (UID > 1000)
+- `readonly_root: true` unless explicitly justified
+- Drop all capabilities except those required
+- `no-new-privileges: true`
+- Pin specific image versions (no `latest` tag)
+- No hardcoded secrets
+
+## Security Disclosure
+
+**Do NOT open public issues for security vulnerabilities.**
+
+Email security concerns to the maintainers directly. Include:
+
+1. Description of the vulnerability
+2. Steps to reproduce
+3. Potential impact
+4. Suggested fix (if any)
+
+We will acknowledge receipt within 48 hours and provide a timeline for a fix.

 #### Sprint 26: Community Infrastructure (Week 5-8)
 
-- [ ] **COMM-01** — Set up update server infrastructure. Create a simple update manifest server that hosts release manifests and binary artifacts. Can be a static file server or GitHub Releases. Update `UPDATE_MANIFEST_URL` in `core/archipelago/src/update.rs`. **Acceptance**: Update checker finds real releases.
