+# Submitting a Pull Request
+
+Step-by-step for contributors who already have a fork and a working fix.
+
+---
+
+## 1 — Set up your fork
+
+```bash
+# Clone your fork
+git clone https://github.com/<your-username>/OmniRoute.git
+cd OmniRoute
+
+# Add the upstream repo so you can sync
+git remote add upstream https://github.com/diegosouzapw/OmniRoute.git
+
+# Install dependencies (.env is auto-created from .env.example)
+npm install
+```
+
+---
+
+## 2 — Sync with the current release branch
+
+PRs go to **`release/v3.8.3`**, not `main`.
+
+```bash
+git fetch upstream
+git checkout -b fix/your-description upstream/release/v3.8.3
+```
+
+If you already made your changes on another branch, rebase on top of it:
+
+```bash
+git fetch upstream
+git rebase upstream/release/v3.8.3
+```
+
+---
+
+## 3 — Branch naming
+
+| Prefix      | Use for                                 |
+| ----------- | --------------------------------------- |
+| `feat/`     | new feature                             |
+| `fix/`      | bug fix                                 |
+| `refactor/` | code restructuring (no behavior change) |
+| `docs/`     | documentation only                      |
+| `test/`     | tests only                              |
+| `chore/`    | tooling, deps, CI                       |
+
+Examples: `fix/codex-token-refresh`, `feat/provider-xyz`, `docs/update-readme`
+
+---
+
+## 4 — Validate before committing
+
+```bash
+npm run lint          # must pass (0 errors)
+npm run typecheck:core  # must pass
+npm run test:unit     # must pass
+npm run test:coverage # coverage gate: 75/75/75/70
+```
+
+If you changed production code in `src/`, `open-sse/`, `electron/`, or `bin/`, include or update tests in the same PR.
+
+---
+
+## 5 — Commit
+
+Follow [Conventional Commits](https://www.conventionalcommits.org/):
+
+```
+feat(dashboard): add provider search filter
+fix(combo): resolve pending request leak on timeout
+docs(readme): update installation steps
+test(auth): add JWT expiry edge case
+```
+
+Common scopes: `api`, `dashboard`, `db`, `sse`, `oauth`, `providers`, `combo`, `mcp`, `cli`, `i18n`
+
+---
+
+## 6 — Push and open the PR
+
+```bash
+git push -u origin fix/your-description
+```
+
+Then open a PR on GitHub targeting **`diegosouzapw/OmniRoute`** → **`release/v3.8.3`**.
+
+PR description checklist:
+
+- [ ] What the change does (1–3 bullets)
+- [ ] How to test it
+- [ ] Test files added or updated (if production code changed)
+
+---
+
+## 7 — After opening the PR
+
+- CI runs lint + typecheck + tests automatically.
+- Address review comments with new commits (do not force-push after review starts).
+- If the base branch advances, sync with:
+
+```bash
+git fetch upstream
+git rebase upstream/release/v3.8.3
+git push --force-with-lease
+```
+
+---
+
+## Quick reference
+
+```bash
+# Full validation in one command
+npm run lint && npm run typecheck:core && npm run test:coverage
+
+# Run a single test file
+node --import tsx/esm --test tests/unit/your-file.test.ts
+
+# Start dev server
+npm run dev   # http://localhost:20128
+```
