 **ggbridge** is distributed as a Distroless Docker image based on Wolfi OS, ensuring minimal dependencies and enhanced security.
 Additionaly, a **shell** variant of the Docker image is available, this version includes additional tools and allows you to connect to the container via a shell, facilitating troubleshooting and debugging during development or integration.
 
-The project offers two deployment methods:
-
-- **Docker Deployment**: Ideal for local testing or simpler use cases.
-- **Helm Chart Deployment**: The preferred method for production environments, offering enhanced configurability and scalability for Kubernetes setups.

-### Docker deployment
-
-> [!WARNING]  
-> Please consider that [Docker deployment](#docker-deployment) mode is intended for testing purposes. We highly recommend using [Helm deployment](#helm-deployment) mode.
-
-Deploy the ggbridge client via Docker Compose by performing the following actions:
-
-- Create `docker-compose.yml` file
-
-> [!IMPORTANT]  
-> GGBridge is designed by default to work as HA, so it needs `3` client deployments to work properly. Ensure `replicas: 3` in your `docker-compose.yml` file. If you lower the replica count, it may result in an unstable bridge.
->
-> ```yaml
-> services:
->   client:
->     deploy:
->       replicas: 3
-> ```
-
-```yaml
-name: ggbridge
-
-services:
-  client:
-    image: gitguardian/ggbridge:latest-shell
-    environment:
-      SERVER_ADDRESS: <my-subdomain>.ggbridge.gitguardian.com
-      TLS_ENABLED: 'true'
-    deploy:
-      replicas: 3
-    volumes:
-      - ./tls/ca.crt:/etc/ggbridge/tls/ca.crt:ro
-      - ./tls/tls.crt:/etc/ggbridge/tls/client.crt:ro
-      - ./tls/tls.key:/etc/ggbridge/tls/client.key:ro
-      - ./docker/nginx/nginx.local.conf:/etc/ggbridge/nginx.conf
-    restart: on-failure
-```
-
-- Run `docker-compose`
-
-```shell
-docker compose up -d
-```
+The project can be deployed on Kubernetes-like infrastructure (k0s, k3s, Talos, EKS, GKE, AKS...). GGBridge leverages **Helm Chart Deployment** which is an industry standard method for production environements, offering enhanced configurability and scalability for Kubernetes setups.
