+# Development Environment Setup Guide
+
+## Prerequisites
+
+- Windows, macOS, or Linux
+- Git
+- Docker Desktop
+- Visual Studio Code with Remote - Containers extension
+- GitHub CLI
+
+## Initial Setup
+
+1. **Clone the Repository**
+   ```bash
+   git clone https://github.com/acedanger/finance.git
+   cd finance
+   ```
+
+2. **Create Environment Files**
+   ```bash
+   cp .devcontainer/.env.example .devcontainer/.env
+   cp .env.example .env
+   ```
+
+## GitHub Personal Access Token (PAT)
+
+1. **Create a new PAT:**
+   - Go to GitHub Settings > Developer settings > Personal access tokens > Tokens (classic)
+   - Click "Generate new token (classic)"
+   - Name: `finance-dev-token`
+   - Set expiration: 90 days (recommended)
+   - Required scopes:
+     - `repo` (Full control of private repositories)
+     - `read:packages` (Download container images)
+     - `write:packages` (Upload container images)
+     - `delete:packages` (Optional: manage container versions)
+     - `workflow` (GitHub Actions integration)
+
+2. **Configure the PAT:**
+   - Open `.devcontainer/.env`
+   - Set `GITHUB_PERSONAL_ACCESS_TOKEN=your_token_here`
+
+## Building the Development Container
+
+### Using VS Code (Recommended)
+1. Open the project in VS Code
+2. When prompted, click "Reopen in Container"
+   - Or press F1 and run "Dev Containers: Rebuild and Reopen in Container"
+
+### Using Command Line
+1. Install the devcontainer CLI:
+   ```bash
+   npm install -g @devcontainers/cli
+   ```
+
+2. Build the container:
+   ```bash
+   devcontainer build .
+   ```
+
+3. Start the container:
+   ```bash
+   # With post-create command
+   devcontainer up --workspace-folder .
+
+   # Skip post-create command
+   devcontainer up --workspace-folder . --skip-post-create
+   ```
+
+## Building and Pushing the Container Image
+
+1. Ensure you're in the `.devcontainer` directory
+
+2. Choose your preferred script:
+
+   **Using PowerShell:**
+   ```powershell
+   .\build-and-push.ps1 your_github_username
+   ```
+
+   **Using Git Bash/Unix Shell:**
+   ```bash
+   chmod +x build-and-push.sh
+   ./build-and-push.sh your_github_username
+   ```
+
+Both scripts perform the same functions:
+- Validate prerequisites (Docker, GitHub CLI)
+- Load GitHub PAT from `.env` file
+- Build the container image
+- Push to GitHub Container Registry
+- Provide next steps for using the image
+
+## Environment Files
+
+The project uses two separate environment files:
+
+1. `.devcontainer/.env`:
+   - Container-specific configuration
+   - GitHub PAT
+   - PostgreSQL settings
+   - pgAdmin settings
+
+2. `.env`:
+   - Application-specific configuration
+   - Development server port
+   - API base URL
+   - Node environment
+
+## Troubleshooting
+
+### Container Build Issues
+- Ensure Docker Desktop is running
+- Check that your PAT has the correct permissions
+- Try rebuilding without cache: `devcontainer build . --no-cache`
+
+### GitHub Authentication Issues
+- Verify your PAT in `.devcontainer/.env`
+- Try logging in manually: `gh auth login`
+- Check GitHub CLI status: `gh auth status`
+
+### Network Issues
+- If DNS resolution fails, try using different DNS servers in `devcontainer.json`
+- Check if GitHub Container Registry (ghcr.io) is accessible
+- Verify Docker network settings
+
+### VS Code Issues
+- Install/update the Remote - Containers extension
+- Clear VS Code's container cache
+- Check VS Code's "Dev Containers" output panel for detailed logs
+
+## Common Operations
+
+### Rebuilding the Container
+```bash
+# Using VS Code
+F1 -> "Dev Containers: Rebuild Container"
+
+# Using CLI
+devcontainer build . --no-cache
+```
+
+### Updating the Container Image
+1. Make changes to `Dockerfile` or `devcontainer.json`
+2. Run the build script:
+   ```bash
+   ./build-and-push.sh your_github_username
+   ```
+3. Update image reference in `devcontainer.json`
+4. Rebuild container in VS Code
+
+### Starting Development Server
+```bash
+npm run dev
+```
