-# Website
+# OpenTDF Documentation
+
+> The official documentation website for OpenTDF - an open source toolkit for zero trust, data-centric security.
+
+## About This Repository
+
+This repository contains the source code for the [OpenTDF documentation website](https://docs.opentdf.io), built using [Docusaurus](https://docusaurus.io/). The documentation provides comprehensive guides, tutorials, and reference materials for developers and organizations implementing data-centric security with OpenTDF.
+
+## What is OpenTDF?
+
+OpenTDF is an open source system for implementing data-centric security that enables:
+
+- **Zero Trust Data Protection**: Cryptographically bind access control policies to data objects
+- **Attribute-Based Access Control (ABAC)**: Fine-grained access decisions based on attributes and context
+- **Policy Travels with Data**: Security controls remain attached wherever data goes
+- **Trust Data Format (TDF)**: Open standard for self-protecting data
+
+## Documentation Structure
+
+Our documentation follows a user-needs approach with four main categories:
+
+- **🚀 Tutorials**: Step-by-step learning experiences for hands-on practice
+- **📖 How-To Guides**: Problem-solving recipes for specific tasks and integrations
+- **💡 Explanations**: Conceptual guides covering the "why" behind OpenTDF's design
+- **📚 Reference**: Technical specifications, API docs, and lookup information
+
+## Contributing
+
+We welcome contributions to improve our documentation! Please see our [Contributing Guide](CONTRIBUTING.md) for guidelines on:
+
+- Writing and editing documentation
+- Style and formatting standards
+- Review and approval process
+- Technical setup for contributors
+
+For style guidelines, please refer to our [Style Guide](STYLE_GUIDE.md).

+## Local Development
 
 This website is built using [Docusaurus](https://docusaurus.io/), a modern static website generator.
 
-### Installation
+### Prerequisites
 
+Before you can run the documentation locally, you'll need Node.js and npm. We recommend using nvm (Node Version Manager) to manage Node.js versions.
+
+#### Option 1: Using nvm (Recommended)
+
+nvm allows you to install and switch between different Node.js versions easily.
+
+**Installation:**
+
+- **macOS/Linux**: Follow the installation instructions at [nvm GitHub repository](https://github.com/nvm-sh/nvm#installation-and-update)
+- **Windows**: Install nvm-windows from [nvm-windows releases](https://github.com/coreybutler/nvm-windows#installation--upgrades)
+
+**Verify installation:**
+
+```bash
+nvm --version  # macOS/Linux
+nvm version    # Windows
 ```
-$ nvm use
-$ npm ci
-```
+
+#### Option 2: Direct Node.js Installation
+
+If you prefer not to use nvm:
+
+1. **Visit [nodejs.org](https://nodejs.org/)** and download **Node.js version 22** (the version specified in our `.nvmrc` file)
+2. **Follow the installation instructions** for your operating system
+3. **Verify installation:**
+
+   ```bash
+   node --version  # Should show v22.x.x
+   npm --version   # Should show npm version
+   ```
+
+### Installation
+
+1. **Clone the repository:**
+
+   ```bash
+   git clone https://github.com/opentdf/docs.git
+   cd docs
+   ```
+
+2. **Use the correct Node.js version** (if using nvm):
+
+   ```bash
+   nvm use  # This reads the .nvmrc file and switches to Node.js v22
+   ```
+
+   If you don't have Node.js v22 installed via nvm:
+
+   ```bash
+   nvm install 22
+   nvm use 22
+   ```
+
+3. **Install dependencies:**
+
+   ```bash
+   npm ci  # Installs exact versions from package-lock.json
+   ```
 
 ### Local Development
 
-```
-$ npm run start
-```
+   ```bash
+   npm run start
+   ```
 
 This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.
 
 ### Build
 
+   ```bash
+   npm run build
+   ```
+
+This command generates static content into the `build` directory and can be served using any static contents hosting service.
+
+### Testing with Feature Branches
+
+The documentation site pulls content from multiple upstream repositories using Docusaurus remote content plugins. By default, content is fetched from the `main` branch of each repository. You can override this behavior using environment variables to test documentation changes from feature branches before they're merged.
+
+**Available Environment Variables:**
+
+- `PLATFORM_BRANCH` - Controls which branch to fetch from `opentdf/platform` (default: `main`)
+- `SPEC_BRANCH` - Controls which branch to fetch from `opentdf/spec` (default: `main`)
+- `OTDFCTL_BRANCH` - Controls which branch to fetch from `opentdf/otdfctl` (default: `main`)
+
+**Examples:**
+
+Test with all feature branches:
+```bash
+PLATFORM_BRANCH=my-platform-feature SPEC_BRANCH=my-spec-feature OTDFCTL_BRANCH=my-cli-feature npm run build
 ```
-$ npm run build
+
+Test with a single feature branch:
+```bash
+SPEC_BRANCH=feature-branch-name npm run build
 ```
 
-This command generates static content into the `build` directory and can be served using any static contents hosting service.
+Test in development mode with feature branches:
+```bash
+PLATFORM_BRANCH=my-feature npm run start
+```
+
+**Use Cases:**
+
+- **Before merging PRs**: Test how documentation changes from upstream repos will look when integrated
+- **Cross-repo changes**: When making coordinated changes across multiple repositories, test the full integration locally
+- **Debugging**: Investigate issues with specific branches without affecting your local main branch
+
+**Note**: The branches must exist in the respective GitHub repositories and be accessible (public or you have access).
