 # Kapsule/Kosmos agent
 
-A Kubernetes node installer and lifecycle management tool for Scaleway's managed Kubernetes services (Kapsule and Kosmos).
+Kubernetes node installer and lifecycle manager for Scaleway's managed Kubernetes services (Kapsule and Kosmos).
 
-## Overview
+## Documentation
 
-k8s-agent is a comprehensive node management solution that bootstraps Kubernetes nodes, manages component lifecycles, and provides ongoing node management through a Kubernetes controller. It's designed to work with Scaleway's infrastructure.
-
-## Features
-
-- **Component-based Architecture**: Install and manage Kubernetes components via YAML-defined metadata
-- **Template Support**: Dynamic configuration generation with Sprig template functions
-- **Version Management**: Track component versions with sub-versioning support
-- **Multi-repository Support**: HTTP/HTTPS and ZIP file repositories
-
-## Architecture
-
-### Core Components
-
-- **Bootstrap Mode**: Installs required components and configurations on new nodes
-- **Controller Mode**: Kubernetes controller that watches for upgrade requests
-- **Metadata Service**: Fetches node configuration from Scaleway infrastructure
-- **Component Manager**: Handles installation, upgrades, and lifecycle management
-- **Version Tracker**: Maintains component version state in `/etc/scw-k8s-versions.json`
-
-### Component Processing
-
-Components are defined in YAML metadata with support for:
-- File operations (copy, mkdir, ...)
-- Template rendering with node metadata
-- Systemd service management
-- Script execution
-
-## Version Management
-
-Component versions are tracked in `/etc/scw-k8s-versions.json`. The agent supports:
-- Semantic versioning
-- Sub-versioning with `~` prefix
-- Component lifecycle tracking
