+# Installation Guide
+
+## Prerequisites
+- Python 3.8 or higher
+- pip (Python package installer)
+
+## Installation Steps
+
+1. Clone the repository:
+```bash
+git clone https://github.com/stitionai/devika.git
+cd devika
+```
+
+2. Install dependencies:
+```bash
+pip install -r requirements.txt
+```
+
+## Common Issues
+
+### Missing numpy dependency
+If you encounter an error about numpy not being available, install it explicitly:
+```bash
+pip install numpy>=1.24.0
+```
+
+## Troubleshooting
+If you encounter any installation issues:
+1. Ensure you have Python 3.8 or higher installed
+2. Try upgrading pip: `pip install --upgrade pip`
+3. Install numpy explicitly if needed: `pip install numpy>=1.24.0`
