 SageMath fully supports all major Linux distributions, recent versions of macOS, and Windows (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).
+See https://doc.sagemath.org/html/en/installation/index.html
+for general installation instructions.

 Building `sagemath-standard` has a large number of system packages as prerequisites.
 See https://doc.sagemath.org/html/en/installation/source.html#linux-recommended-installation
 for partial lists for various systems.
 
-The connection to the system environment is facilitated through the https://pypi.org/project/sage-conf/ distribution package.

 A modularization effort is in progress with the goal of making it possible to install parts of the Sage Library with fewer prerequisites. https://github.com/sagemath/sage/issues/29705
