+# Contributing
+
+First off, thank you for taking the time to contribute to **Video.js 10** ❤️
+Your input helps shape the next generation of open web media players.
+
+## 🎒 Getting Started
+
+### Requirements
+
+You’ll need the following installed:
+
+- [Node.js](https://nodejs.org/en/download) (≥ 22.19.0)
+- [Git](https://git-scm.com/downloads)
+- [PNPM](https://pnpm.io/installation) (≥ 10.17.0)
+- [Volta](https://docs.volta.sh/guide) or [NVM](https://github.com/nvm-sh/nvm) (we recommend Volta for automatic Node management)
+
+> 💡 **Tip:** PNPM will automatically use the correct Node version when running scripts.
+> If you prefer NVM: after installing it, simply run `nvm use` in the repo root.
+
+---
+
+### Fork & Clone
+
+1. [Fork on GitHub][vjs-gh].
+2. Clone your fork locally and set up upstream tracking:
+
+```bash
+git clone https://github.com/{your-github-username}/vjs-10-monorepo.git
+cd vjs-10-monorepo
+
+git remote add upstream git@github.com:videojs/vjs-10-monorepo.git
+git fetch upstream
+git branch --set-upstream-to=upstream/main main
+```
+
+To update your local main branch later:
+
+```bash
+git pull upstream --rebase
+```
+
+---
+
+### Install Dependencies
+
+```bash
+pnpm install
+```
+
+Then build all workspace packages:
+
+```bash
+pnpm build:packages
+```
+
+> ℹ️ **VS Code Users:** the project may suggest extensions to enhance the developer
+> experience.
+> If imports like `react` are not resolving, set your TS version to the workspace one:
+> `CMD/CTRL + Shift + P` → `TypeScript: Select TypeScript Version` → _Use Workspace Version_.
+
+---
+
+## 🏗 Development
+
+Run the workspace in development mode:
+
+```bash
+pnpm dev
+```
+
+To run a specific app:
+
+```bash
+pnpm dev:html
+pnpm dev:react
+pnpm dev:site
+```
+
+---
+
+## 🧹 Linting
+
+Ensure your code follows our lint rules with:
+
+```bash
+pnpm lint
+pnpm lint:fix
+```
+
+Pre‑commit hooks automatically lint staged files via **simple-git-hooks** and **lint‑staged**.
+
+---
+
+## 🧪 Testing
+
+We use [Vitest](https://vitest.dev) for unit testing.
+
+Run tests with:
+
+```bash
+pnpm test                 # all workspace tests
+pnpm test:core            # just core package
+pnpm test:core --watch
+pnpm test:core file.spec
+```
+
+---
+
+## 📦 Managing Dependencies
+
+To add a dependency to a specific package:
+
+```bash
+pnpm -F <scope> add <package>
+# Example:
+pnpm -F react add @floating-ui/react-dom
+```
+
+To upgrade a dependency across all packages:
+
+```bash
+pnpm up <package>@<version> -r
+```
+
+---
+
+## ✍️ Committing
+
+We follow **[semantic commit messages][semantic-commit-style]** to enable automated releases.
+
+Examples:
+
+- `feat(core): add volume smoothing hook`
+- `fix(react): correct prop mapping for picture-in-picture`
