+# 🏡 Home Assistant Newt Add-on
+
+## 📌 About this Add-on
+This Home Assistant add-on allows you to easily run **Newt** from [Fossorial](https://docs.fossorial.io/Newt/overview) directly in Home Assistant. The add-on lets you configure **PANGOLIN_ENDPOINT**, **NEWT_ID**, and **NEWT_SECRET** via the Home Assistant interface.
+
+## 🚀 Features
+✅ Easy installation via Home Assistant Add-on Store  
+✅ Automated setup and execution of the Newt container  
+✅ Supports `amd64`, `armv7`, `armhf`, and `aarch64` architectures  
+✅ Automatic restart on crash  
+
+---
+
+## 🛠️ Installation
+
+### **1️⃣ Add the GitHub Repository as an Add-on Source**
+1. Go to **Settings → Add-ons → Add-on Store**.
+2. Click the menu (three dots in the top right) and select **Repositories**.
+3. Add the following URL:
+   ```
+   https://github.com/username/home-assistant-newt-addon
+   ```
+4. Click **Add** and wait for the repository to load.
+
+### **2️⃣ Install and Start the Add-on**
+1. Find **Newt Add-on** in the list and click **Install**.
+2. Go to the **Configuration** tab and enter your values for:
+   - **PANGOLIN_ENDPOINT** (e.g., `https://example.com`)
+   - **NEWT_ID**
+   - **NEWT_SECRET**
+3. Click **Save** and then **Start**.
+4. Check the **Logs** tab to verify that everything is running correctly.
+
+---
+
+## ⚙️ Configuration
+After installation, you can configure the add-on via the Home Assistant UI:
+
+```yaml
+PANGOLIN_ENDPOINT: "https://example.com"
+NEWT_ID: "your_newt_id"
+NEWT_SECRET: "your_newt_secret"
+```
+
+### **Docker Environment Variables**
+The following environment variables are passed to the `Newt` container:
+- `PANGOLIN_ENDPOINT`
+- `NEWT_ID`
+- `NEWT_SECRET`
+
+---
+
+## 🔍 Troubleshooting
+💡 **Add-on does not start?**
+- Check the logs in Home Assistant (`Settings → Add-ons → Newt → Logs`).
+- Ensure that `PANGOLIN_ENDPOINT`, `NEWT_ID`, and `NEWT_SECRET` are set correctly.
+
+💡 **Changes in configuration do not take effect?**
+- Restart the add-on after making changes.
+- Try removing the container manually:
+  ```sh
+  docker stop newt
+  docker rm newt
+  ```
+  Then start the add-on again.
+
+💡 **Docker not available?**
+- Home Assistant OS manages Docker automatically, but check if the system has access to Docker by running:
+  ```sh
+  docker info
+  ```
+  If this fails, there may be a restriction in Home Assistant OS.
