+# Using These Notes
+
+These notes are built via [Jupyter book](https://jupyterbook.org/), as
+a collection of [Jupyter](https://jupyter.org/) notebooks and markdown
+pages.
+
+The course is on Github at:
+https://github.com/sbu-python-class/python-science, and the course
+website is built automatically via a Github action each time a change
+is pushed.
+
+If you find any problems or have suggestions for improving the notes,
+feel free to create an issue or pull request at the Github repo.
+
+## Interactive Usage
+
+For the Jupyter notebooks in this collection, there are a few ways to
+access them to run them on your own.
+
+* clicking on the {octicon}`download` icon in the upper right let's
+  you download the raw notebook so you can run it on your local
+  computer.
+
+* clicking on the {octicon}`rocket` icon in the upper right will allow
+  you to run the notebook directly in the cloud.  There are 2 different
+  compute clouds:
+
+  * [mybinder](https://mybinder.org/) : this is an open project with
+    ties to the Jupyter project.  It can take a few minutes for the
+    page to appear if it hasn't been accessed recently, but then it
+    will give you the standard Jupyter experience.
+
+  * [Google colab](https://colab.research.google.com/) : this is
+    Google's version of an online notebook, which runs directly in
+    Google's cloud.  This starts up almost instantly.
