+# In this project we craete the application called "DELL-E Image Genartor" by using React 
+
+DELL-E Image Generator is the application that is used for creating images by describing what you want to see! After generating images, you can post and download your images.
+
+This project uses OpenAI to generate images and cloudinary to store images.
+
+## How to use this application on your local?
+* You will need OpenAI API key
+* You will need Cloudinary API Key
+* You will also need to connect with MongoDB 
+* Create a `.env` file. This file is used to store the keys that access the API services and the database
+```bash
+touch .env # to create the .env file
+echo 'MONGODB_URL=""' >> .env 
+echo 'CLOUD_NAME=""' >> .env
+echo 'CLOUD_API_KEY=""' >> .env
+echo 'CLOUD_SECRET=""' >> .env
+echo 'OPENAI_API_KEY=""' >> .env
+```
+Fill in the information with your keys to complete the .env file.
+
+## To start the project
+  
+* `npm start` on client side
+* `npm start` on server side
