+## Installation steps
+
+1. - Fork the [repo](https://github.com/codedmachine111/Image_generation_using_transformers_in_GANs)
+   - Clone the repo to your local machine `git clone https://github.com/codedmachine111/Image_generation_using_transformers_in_GANs.git`
+   - Change current directory `cd Image_generation_using_transformers_in_GANs`
+2. Install latest version of [Python](https://www.python.org/) and create a virtual environment:
+```bash
+python -m venv venv
+./venv/Scripts/activate
+```
+
+3. Install all dependencies:
+```bash
+pip install -r requirements.txt
+```
+
+4. Train the model and see the output images in the '/output' dir
+
+```bash
+python main.py
+```
