This is a "beta" of the machinery that will eventually be used to store STScI notebooks.
To add a notebook, create a directory for the notebook inside "imregcomb". Inside that directory, place your notebook, and a "requirements" file. In the requirements file you should put everything your notebook requires to work including a version number. Include there a "known good" version number - e.g., "numpy==1.14" if you've tested on numpy 1.14.
Once you've done this, git add and git commit. NEVER COMMIT A NOTEBOOK WITH OUTPUTS. That is, always clear the outputs before committing.
To execute your notebook and see it rendered as a web page, go to the root of this repo (where the README is) and do python convert.py. Then open up the generated index.html and follow it to your notebook.
