 # DeepForge
 DeepForge is an open-source visual development environment for deep learning. Currently, it supports Convolutional Neural Networks but we are planning on supporting additional deep learning classifiers such as RNNs and LSTMs. Additional features include real-time collaborative editing and version control.
 
-## Quick Setup
-After cloning the repo, run
+## Quick Start
+Simply run the following command to install deepforge with its dependencies:
 
 ```
-npm install && npm start
+curl -o- https://raw.githubusercontent.com/dfst/deepforge/master/install.sh | bash
 ```
 
-Now, navigate to `localhost:8888` in a browser and create a new project. Select `nn` as the seed and start creating your neural nets!
+Next, follow the postinstall instructions to start MongoDB and DeepForge!
+
+Finally, navigate to [http://localhost:8888](http://localhost:8888) to start using DeepForge! For more, detailed instructions,check out our [wiki](https://github.com/dfst/deepforge/wiki/Installation-Guide).
 
 ## Caffe Support?
 DeepForge uses Torch to perform the actual training and testing of the models. If you are interested in DeepForge using Caffe for actual training and testing, check out [DeepForge-Caffe](https://github.com/dfst/deepforge-caffe).
