## 🚀 Step-by-Step Installation Guide

### 1. **Install Coolify**

SSH into your server and run:

“`bash
curl -fsSL https://cdn.coollabs.io/coolify/install.sh | sudo bash
“`

This script installs Coolify and its dependencies. Once done, access the Coolify dashboard at `http://your-server-ip:8000` and create your admin account.

### 2. **Set Up Vaultwarden in Coolify**

– **Add a New Application:**
– In the Coolify dashboard, click on “Add New Application.”
– Choose “Docker Compose” as the deployment method.

– **Configure the Repository:**
– If you have a Git repository with your Vaultwarden setup, link it. Otherwise, you can create a new one or use a public template.

– **Define Environment Variables:**
– Set necessary environment variables such as `DOMAIN`, `ADMIN_TOKEN`, etc.

– **Deploy the Application:**
– Click on “Deploy” and let Coolify handle the rest.

### 3. **Configure Domain and SSL**

– **DNS Settings:**
– Point your domain’s A record to your server’s IP address.

– **Enable HTTPS:**
– In Coolify, navigate to your application’s settings and enable SSL. Coolify will automatically obtain and configure Let’s Encrypt certificates.

## 🔐 Security and Optimization Tips

– **Use Strong Admin Tokens:**

– Only open necessary ports (e.g., 80 and 443) to the public.

– **Monitor Logs:**
– Regularly check application logs for any suspicious activity.
