+# Sample IRIS API Application
+
+Build IRIS Machine Learning Model using Scikit-Learn and deploy using Tornado Web Framework.
+
+## Setup Environment on Local Machine
+
+### Installation
+
+```
+cookiecutter https://github.com/sampathweb/cc-iris-api
+
+cd <repo>  # cd iris-api
+
+# Install Packages
+python env/create_env.py
+source activate env/venv  # Windows users: activate env/venv
+python env/install_packages.py
+
+# Build the Model
+python ml_src/build_model.py
+
+# Run the App
+python run.py
+````
+
+### Test App
+
+
+1. Open Browser:  [http://localhost:9000](http://localhost:9000)
+
+2. Command Line:
+
+```
+curl -i http://localhost:9000/api/iris/predict -X POST -d '{ "sepal_length": 2, "sepal_width": 5, "petal_length": 3, "petal_width": 4}'
+```
+
+3. Jupyter Notebook:
+
+Open new terminal navigate to the new folder `iris-api`.  Start `jupyter notebook`. Open ml_src -> `api_client.ipynb`.  Test the API.
+
+Api works!
