+# Scaleway Instance Template
+
+This template provisions Coder workspaces on [Scaleway](https://www.scaleway.com/) cloud instances with full customization options for regions, instance types, operating systems, and storage configurations.
+
+## Features
+
+- **Multi-region support**: Choose from France (Paris), Netherlands (Amsterdam), or Poland (Warsaw)
+- **Flexible instance sizing**: Wide range of instance types from development to high-performance computing
+- **Multiple OS options**: Debian 12/13, Ubuntu 24.04, and Fedora 41
+- **Customizable storage**: Adjustable disk size with configurable IOPS
+- **IPv4 and IPv6 networking**: Dual-stack IP configuration for enhanced connectivity
+
+## Prerequisites
+
+### Scaleway Account Setup
+
+1. Create a [Scaleway account](https://console.scaleway.com/)
+2. Create a new project or use an existing one
+3. Generate API credentials:
+   - Go to **IAM** > **API Keys** in the Scaleway Console
+   - Create a new API key
+   - Note down the **Access Key** and **Secret Key**
+   - Copy your **Project ID** from the project settings
+   - Give permissions for **BlockStorageFullAccess**, **ProjectReadOnly**, **InstancesFullAccess** as a starting point
+
+## Architecture
+
+This template creates the following resources for each workspace:
+
+### Persistent Resources
+
+- **Block Volume**: Mounted as user's home directory (preserves all data, configs, and projects)
+
+### Ephemeral Resources (destroyed when workspace stops)
+
+- **Scaleway Instance**: Virtual machine created fresh on each workspace start
+- **IPv4 Address**: Routed IPv4 address assigned dynamically
+- **IPv6 Address**: Routed IPv6 address assigned dynamically
+- **Cloud-init Configuration**: Automated setup of the Coder agent and persistent storage mounting
+
+## Configuration Options
+
+### Region Selection
+
+Choose from three available regions:
+
+- **France - Paris (fr-par)**: Default, lowest latency for European users
+- **Netherlands - Amsterdam (nl-ams)**: Alternative European location
+- **Poland - Warsaw (pl-waw)**: Eastern European option
+
+### Instance Types
+
+The template supports a comprehensive range of Scaleway instance types:
+
+#### Development Instances
+
+- **STARDUST1-S**: 1 CPU, 1GB RAM - Basic development
+- **DEV1-S/M/L/XL**: 2-4 CPUs, 2-12GB RAM - Standard development
+
+#### Production Instances
+
+- **ENT1 Series**: 2-96 CPUs, 8-384GB RAM - Enterprise workloads
+- **GP1 Series**: 4-48 CPUs, 16-256GB RAM - General purpose
+- **PRO2 Series**: 2-32 CPUs, 8-128GB RAM - Professional workloads
+
+#### Specialized Instances
+
+- **L4 Series**: GPU-enabled instances for AI/ML workloads
+- **COPARM1 Series**: ARM64 architecture for specific use cases
+
+### Operating System Options
+
+- **Debian 13 (Trixie)**: Latest Debian release
+- **Debian 12 (Bookworm)**: Stable Debian LTS
+- **Ubuntu 24.04 (Noble)**: Latest Ubuntu LTS
+- **Fedora 41**: Cutting-edge features and packages
+
+### Storage Configuration
+
+- **Home Directory Size**: 10-500GB adjustable via slider (your entire home directory)
+- **IOPS**: 5,000 or 15,000 IOPS options for performance tuning
+
+## Template Components
+
+### Included Tools
+
+- **VS Code Server**: Browser-based IDE with full extension support
+- **System Monitoring**: CPU, RAM, and disk usage metrics
+- **Dotfiles Support**: Automatic dotfiles synchronization on workspace start
+- **Custom Environment Variables**: Pre-configured welcome message
+
+### Cloud-init Setup
+
+The template uses cloud-init for:
+
+- Automatic Coder agent installation and configuration
+- User account setup with proper permissions
+- Persistent home directory mounting (automatic disk partitioning and filesystem creation)
+- Development tools initialization
+
+## Usage
+
+### Creating a Workspace
+
+1. **Select Template**: Choose "Scaleway Instance" from your Coder templates
+2. **Configure Region**: Pick your preferred Scaleway region
+3. **Choose Instance**: Select instance type based on your performance needs
+4. **Select OS**: Pick your preferred operating system
+5. **Set Home Directory Size**: Adjust storage size (10-500GB) for your persistent home directory
+6. **Create**: Launch your workspace
+
+### Managing Costs
+
+- **VM instances are destroyed** when workspace stops (zero compute costs when not in use)
+- **IP addresses are released** when workspace stops (no static IP charges)
+- **Home directory persists** on dedicated block volume (small storage cost only)
+- **Fresh OS** on each workspace start with persistent user data
+- Choose appropriate instance sizes for your workload requirements
+
+## Customization
+
+### Extending the Template
+
+You can customize this template by:
+
+1. **Adding Software**: Modify cloud-init scripts to install additional tools
+2. **Custom Modules**: Include additional Coder modules from the registry
+3. **Network Configuration**: Adjust security groups or network settings
+4. **Startup Scripts**: Add custom initialization logic
+
+## Maintenance
+
+### Updating Instance Types
+
+To update the available instance types, regenerate the `scaleway-config.json` file:
+
+```bash
+scw instance server-type list -o json | jq 'map({name, cpu, gpu, ram, arch})' > scaleway-config.json.json
+```
+
+This pulls the latest instance types from Scaleway and formats them for use in the template.
