+    Magma, Maple, Mathematica, and MATLAB"
+

+
+   https://www.sagemath.org
+
+SageMath fully supports all major Linux distributions, recent versions of macOS, and Windows (using Cygwin or 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 experimental pip-installable source distribution
+-----------------------------------------------------------
+
+This pip-installable source distribution `sagemath-categories` is an experimental distribution of a small part of the Sage Library.  Use at your own risk.  It provides a small subset of the modules of the Sage library ("sagelib", `sagemath-standard`).  It is a superset of the `sagemath-objects` (providing Sage objects, the element/parent framework, categories, the coercion system and the related metaclasses), making various additional categories available without introducing dependencies on additional mathematical libraries.
