-Caching with devpi
-------------------
-
-devpi is a caching proxy server which you run on your laptop, or some other
-machine you know will always be available to you. See the `devpi
-documentation for getting started`__.
-
-__ https://devpi.net/docs/devpi/devpi/latest/+d/quickstart-pypimirror.html
-
-
-Complete mirror with bandersnatch
-----------------------------------
-
-bandersnatch will set up a complete local mirror of all PyPI :term:`packages
-<Distribution Package>` (externally-hosted packages are not mirrored). See
-the `bandersnatch documentation for getting that going`__.
-
-__ https://github.com/pypa/bandersnatch/
-
-A benefit of devpi is that it will create a mirror which includes
-:term:`packages <Distribution Package>` that are external to PyPI, unlike
-bandersnatch which will only cache :term:`packages <Distribution Package>`
-hosted on PyPI.
