+# Akamai Provider for CNCF Self-Hosted Runners
+
+This directory contains automation tools and configurations for deploying and managing CNCF GitHub self-hosted runners on Akamai infrastructure.
+
+## Overview
+
+The Akamai provider enables CNCF projects to leverage Akamai's cloud infrastructure for running CI/CD workflows with GitHub Actions. These self-hosted runners offer enhanced performance, customized environments, and dedicated resources tailored to CNCF project needs.
+
+This automation specifically provisions and manages **Linode managed Kubernetes clusters** and deploys **Actions Runner Controller (ARC)** to handle GitHub Actions workloads efficiently.
+
+## Features
+
+- Automated provisioning of managed Kubernetes clusters on Linode
+- Deployment and configuration of Actions Runner Controller (ARC)
+- Runner configuration and registration with GitHub
+- Auto-scaling capabilities based on workflow demand
+- Monitoring and maintenance utilities
+- Support for multiple GitHub organizations and repositories
+
+## Prerequisites
+
+- Akamai cloud account with appropriate permissions
+- Linode API credentials for Kubernetes cluster management
+- Service account credentials configured for automation
+- GitHub Personal Access Token (PAT) with appropriate permissions
+
+## Configuration
+
+Configuration is managed through environment variables and config files:
+
+- `AKAMAI_API_KEY`: API key for accessing Akamai services
+- `AKAMAI_API_SECRET`: API secret for authentication
+- `LINODE_API_TOKEN`: API token for Linode Kubernetes service
+- `GITHUB_PAT`: GitHub Personal Access Token for runner registration
+
+See the sample configuration file in `config-example.yaml` for detailed settings.
+
+## Usage
+
+Detailed usage instructions for provisioning and managing runners are coming soon.
+
+## Kubernetes Deployment
+
+This provider automatically:
+1. Creates a Kubernetes cluster in Linode
+2. Installs and configures Actions Runner Controller using Helm
+3. Sets up runner scale sets for GitHub repositories/organizations
+4. Configures auto-scaling based on workflow demand
+
+## Troubleshooting
+
+Common issues and their solutions will be documented as they are encountered.
