-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
+   # Run database migrations
+   npx prisma migrate dev
+   
+   # Seed the database with initial data (optional)
+   npx prisma db seed
    ```
 
-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

-The project uses two separate environment files:
+The project uses an `.env` file for configuration:
 
-1. `.devcontainer/.env`:
-   - Container-specific configuration
-   - GitHub PAT
-   - PostgreSQL settings
-   - pgAdmin settings

-   - Application-specific configuration
-   - Development server port

 ## 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`
+### Database Issues
+- Ensure PostgreSQL is running
+- Check that your database connection string is correct in `.env`
+- Try resetting the database: `npx prisma migrate reset`
 
-### GitHub Authentication Issues
-- Verify your PAT in `.devcontainer/.env`
-- Try logging in manually: `gh auth login`
-- Check GitHub CLI status: `gh auth status`
+### Build Issues
+- Clear node_modules and reinstall: `Remove-Item -Recurse -Force node_modules; npm install`
+- Check that all environment variables are set correctly
+- Ensure you have the correct Node.js version installed
 
-### 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
