+This library facilitates the assembly of literate programming documents
 with molecular images made by PyMOL. PyMOL is the most popular
-molecular graphics program for making images for publication; it has
-over 100,000 users, which is a lot of users in the sciences. PyMOL was
-used to make many of the striking images of biological molecules on
-the cover of Nature and Science. We use the emacs-jupyter package to
-send commands from a code block in Org files to PyMOL's Python API.
-PyMOL returns the molecular image to the output block below the
-code block. Of course, an Emacs user can convert the Org file into a
-PDF, convert the code blocks to script files, and submit these for
-non-Emacs users. We describe the content of the library and provide
-examples of the running PyMOL from Org-mode. We compare using Org,
-Jupyter Notebook, Jupyter Lab, and RStudio with PyMOL to do
-literate programming in structural biology.
