# MkDocs Integration tests

This is a simple integration test that builds the MkDocs
documentation against all of the builtin themes.

From the root of the MkDocs git repo, use:

    python -m mkdocs.tests.integration --help


TODOs
    - Build with different configuration options.
    - Build documentation other than just MkDocs as it is relatively simple.
