+# Cosmos Node Installer with Cosmovisor Support
+
+A Bash script to automate the setup of Cosmos SDK-based nodes with optional Cosmovisor integration.
+
+This tool simplifies the setup process by configuring environment variables, installing Cosmovisor, and creating a systemd service to manage your node binary.
+
+---
+
+## 🚀 Features
+
+- Cosmos SDK node setup
+- Cosmovisor installer (version selection)
+- systemd service generator
+- Automated environment variable setup
+- Minimal manual config
+
+---
+
+## 📦 Prerequisites
+
+- **Golang installed** (`>=1.17`)
+- GitHub project details for the Cosmos-based chain you want to install
+- `go` in your system `PATH`
+- Superuser (`sudo`) access
+
+---
+
+## 📁 Script Arguments
+
+| Flag | Description |
+|------|-------------|
+| `-p` | Path to your Cosmos binary (e.g., `/home/user/go/bin/desmos`) |
+| `-b` | Binary name (e.g., `desmos`) |
+| `-c` | Configuration folder name (e.g., `desmos`) |
+| `-s` | Optional Cosmovisor version (e.g., `v1.6.0`) |
+
+---
+
+## ⚙️ Example Usage
+
+```bash
+bash install.sh -p /root/go/bin/desmos -b desmos -c desmos -s v1.6.0
+``` 
+
+## This will:
+
+- Set required environment variables for `DAEMON_NAME` and `DAEMON_HOME`
+- Install Cosmovisor (interactive version selection)
+- Initialize Cosmovisor with your provided binary
+- Create a systemd service for automatic node management
+- Configure `.profile` for persistence across sessions
+
+---
+
+## 🛠 Cosmovisor Version Options
+The script prompts you to choose one of:
+- `v1.6.0 (Recommended)`
+- `v1.3.0`
+- `latest`
+
+You can also predefine a version using `-s` flag to skip the prompt.
+
+---
+
+## 🔁 What It Does Under the Hood
+- Runs [Cosmos SDK’s Cosmovisor](https://docs.cosmos.network/master/run-node/cosmovisor.html)
+- Sets up `~/.profile` with all necessary `DAEMON_*` environment variables
+- Validates `cosmovisor` binary presence or installs it via `go install`
+- Automatically reloads `systemd` and enables the service
+
+---
+
+## 📄 Output Example
+```
+:: Cosmovisor installed...
+:: Cosmosvisor initialised successfully.
+:: Cosmovisor service installed.
+```
