+ Sage: Open Source Mathematics Software: Build system of the Sage documentation
+================================================================================
+
+.. NOTE::
+
+   If you are a developer and want to build the SageMath documentation from source,
+   refer to `developer's guide <../../developer/sage_manuals.html>`_.
+
+About SageMath
+--------------
+
+   "Creating a Viable Open Source Alternative to
+    Magma, Maple, Mathematica, and MATLAB"
+
+   Copyright (C) 2005-2020 The Sage Development Team
+
+   https://www.sagemath.org
+
+SageMath fully supports all major Linux distributions, recent versions of macOS, and Windows (using Windows Subsystem for Linux).
+
+The traditional and recommended way to install SageMath is from source via Sage-the-distribution (https://www.sagemath.org/download-source.html).  Sage-the-distribution first builds a large number of open source packages from source (unless it finds suitable versions installed in the system) and then installs the Sage Library (sagelib, implemented in Python and Cython).
+
+
+About this pip-installable source distribution
+----------------------------------------------
+
+This is the build system of the Sage documentation, based on Sphinx.
