-To install SCS in Matlab from source:
+The easiest way to install SCS in MATLAB is via the pre-compiled toolbox file.
+
+Download Toolbox (.mltbx) - Recommended
+---------------------------------------
+
+The pre-compiled MATLAB Toolbox file includes binaries for Windows, Linux, and Apple Silicon Macs.
+
+1. Go to the `SCS MATLAB interface releases <https://github.com/bodono/scs-matlab/releases>`_ page.
+2. Download the latest ``SCS.mltbx`` file.
+3. Open the file in MATLAB (or double-click it) to install.
+
+Build from Source
+-----------------
+
+If you are on an unsupported platform or prefer to build from source:
+
+1. Clone the repository recursively:
 
 .. code:: bash
 
   git clone --recursive https://github.com/bodono/scs-matlab.git
 
-Then in a Matlab session
+2. In a MATLAB session:
 
 .. code:: matlab
 
   cd <path/to/scs-matlab>
   make_scs
 
-The installer automatically adds scs-matlab to your Matlab path and calls
+The installer automatically adds scs-matlab to your MATLAB path and calls
 ``savepath`` so it persists across sessions. If ``savepath`` fails (e.g., due to
 file permissions) it will print the ``addpath`` line you need to add to your
 ``startup.m``.
 
 See :ref:`here <matlab_interface>` for the API.
