To create a new mitsoheet, open a new or existing Jupyter notebook. For classic Notebook users, you can launch Jupyter with python -m jupyter notebook. For JupyterLab users, you can launch Jupyter with python -m jupyter lab.
Once you've created a new notebook, copy and paste the code below into a Jupyter code cell.
Then run the Mitosheet generating code by clicking on the code cell that contains it and pressing Shift + Enter.
If a Mitosheet does not appear, make sure that you followed the Installation Instructions. If you ran the installer already, make sure to refresh your JupyterLab server.
