 This notebook was used to demo some plotting libraries at BioInfoSummer 2017 and in my [PyConAU 2017 talk](https://www.youtube.com/watch?v=6d3Yk7a2qYI).
 
+If you'd like to run this Jupyter Notebook and/or Dash app yourself, you should be able to install all required packages using:
+
+```
+python -m venv env
+source env/bin/activate
+pip install -r requirements.txt
+```
+
 Depending on what version of Jupyter you're running, you may need to launch this notebook with a higher data rate limit so that visualisation libraries are not throttled in communicating with the browser, e.g.
 
 ```jupyter notebook --NotebookApp.iopub_data_rate_limit=10000000```
