Adding ``sphinx-rtd-theme`` to your project's dependencies will make pip install the latest compatible version of the theme.
If you want to test a **pre-release**, you need to be explicit about the version you specify.
Otherwise, pip will ignore pre-releases. Add for instance ``sphinx-rtd-theme==1.1.0b3`` to test a pre-release.
..tip::
We recommend that you pin the version of Sphinx that your project is built with.
We won't release sphinx-rtd-theme without marking its compatibility with Sphinx. So if you do not pin ``sphinx-rtd-theme`` itself, you will always get the *latest compatible* release.
