+# Python Sandbox in Linux 
+
+Python Sandbox allows you to run your python codes in a complete linux virtual machine. It is easy to use and efficient. The VM is customizable and you can choose your own CPU, disk size, and RAM size. 
+
+Two key features:
+ - Automatic python virtual environment setup.
+ - Same python instructions
+
+## Numpy Example listed in samples/1st.gif
+![](samples/1st.gif)
+
+## Gorilla CLI Example listed in samples/gorillaVM.gif
+![](samples/gorillaVM.gif)
+
+## Requirements
+Please install `qemu` on your machine. Currently, python-sandbox only works on MacOS with M-sereis chips. Windows and Linux versions are not yet tested, and they may potentially work.
+
+## Usage
+
+Darg all relevant python files into this folder. Then, type to see instructions you need to do:
+```bash
+$ python python-sandbox.py --help
+```
+
+## How It Works
+
+python-sandbox internally use lima to create a linux virtual machine. You can edit your linux machine profile in `python-sandbox.yml`. It regulates all of sandboxes you created and make sure there is no conflicts between sandboxes.
+
+### Arguments
+To start a sandbox
+```bash
+python python-sandbox.py start NEWBOX
+```
+To stop a sandbox
+```bash
+python python-sandbox.py stop NEWBOX
+```
+#### Warning: always remember to stop a sandbox! The sanbox does not close on itself. 
+
+To run python 
+```bash
+python python-sandbox.py python PYFILE.py ARGS
+```
+To pip install relevant packages
+```bash
+python python-sandbox.py pip install ARGS
+```
+To show every sandbox status
+```bash
+python python-sandbox.py show-all
+```
+
