+===
+## Best practice for debug NNI source code
+
+For debugging NNI source code, your development environment should be under Ubuntu 16.04 (or above) system with python 3 and pip 3 installed, then follow the below steps.
+
+**1. Clone the source code**
+
+Run the command
+```
+git clone https://github.com/Microsoft/nni.git
+```
+to clone the source code
+
+**2. Prepare the debug environment and install dependencies**
+
+Change directory to the source code folder, then run the command
+```
+make install-dependencies
+```
+to install the dependent tools for the environment
+
+**3. Build source code**
+
+Run the command
+```
+make build
+```
+to build the source code
+
+**4. Install NNI to development environment**
+
+Run the command
+```
+make dev-install
+```
+to install the distribution content to development environment, and create cli scripts
+
+**5. Check if the environment is ready**
+
+Now, you can try to start an experiment to check if your environment is ready
+For example, run the command
+```
+nnictl create --config ~/nni/examples/trials/mnist/config.yml
+```
+And open web ui to check if everything is OK
+
+**6. Redeploy**
+
+After you change some code, just use **step 4** to rebuild your code, then the change will take effect immediately
+
+---
+At last, wish you have a wonderful day.
