+## Simple External Plugin Example
+
+This is a simple example to show how to write an external gQuant plugin. gQuant take advantage of the `entry point` inside the `setup.py` file to register the plugin. gQuant can discover all the plugins that has the entry point group name `gquant.plugin`. Check the `setup.py` file to see details.
+
+### Create an new Python enviroment
+```bash
+conda create -n test python=3.8
+```
+
+### Install the gQuant lib
+To install the gQuant graph computation library, first install the dependence libraries:
+```bash
+pip install dask[dataframe] distributed networkx
+conda install python-graphviz ruamel.yaml numpy pandas
+```
+Then install gquant lib:
+```bash
+pip install gquant
+```
+
+### Install the gQuantlab plugin
+To install JupyterLab plugin, install the following dependence libraries:
+```bash
+conda install nodejs ipywidgets
+```
+Build the ipywidgets Jupyterlab plugin
+```bash
+jupyter labextension install @jupyter-widgets/jupyterlab-manager@2.0
+```
+Then install the gquantlab lib:
+```bash
+pip install gquantlab
+```
+If you launch the JupyterLab, it will prompt to build the new plugin. You can
+explicitly build it by:
+```bash
+jupyter lab build
+```
+
+### Install the external example plugin
+To install the external plugin, in the plugin diretory, run following command
+```bash
+pip install .
+```
+
+### Launch the Jupyter lab
+After launching the JupyterLab by,
+```bash
+jupyter-lab --allow-root --ip=0.0.0.0 --no-browser --NotebookApp.token=''
+```
+You can see the `DistanceNode` and `PointNode` under the name `custom_node` in the menu.
