-NNI (Neural Network Intelligence) is a toolkit to help users run automated machine learning experiments. 
-The tool dispatches and runs trial jobs that generated by tuning algorithms to search the best neural architecture and/or hyper-parameters in different environments (e.g. local machine, remote servers and cloud).

 ## **Who should consider using NNI**
-* You want to try different AutoML algorithms for your training code (model) at local
-* You want to run AutoML trial jobs in different environments to speed up search (e.g. remote servers and cloud)
-* As a researcher and data scientist, you want to implement your own AutoML algorithms and compare with other algorithms
-* As a ML platform owner, you want to support AutoML in your platform
+* Those who want to try different AutoML algorithms in their training code (model) at their local machine.
+* Those who want to run AutoML trial jobs in different environments to speed up search (e.g. remote servers and cloud).
+* Researchers and data scientists who want to implement their own AutoML algorithms and compare it with other algorithms.
+* ML Platform owners who want to support AutoML in their platform.
 
 ## **Install & Verify**
 
-**Install through source code**
+**pip install** 
 * We only support Linux in current stage, Ubuntu 16.04 or higher are tested and supported. Simply run the following `pip install` in an environment that has `python >= 3.5`, `git` and `wget`.
-```bash
-    git clone -b v0.3 https://github.com/Microsoft/nni.git
-    cd nni
-    source install.sh
+```
+python3 -m pip install -v --user git+https://github.com/Microsoft/nni.git@v0.2
+source ~/.bashrc
 ```

+**verify install**
 * The following example is an experiment built on TensorFlow, make sure you have `TensorFlow installed` before running it.
-* And download the examples via clone the source code
-```bash
-    cd ~
-    git clone -b v0.3 https://github.com/Microsoft/nni.git
-```
-* Then, run the mnist example
 ```bash
     nnictl create --config ~/nni/examples/trials/mnist/config.yml
 ```
