+## Changing MATLAB version
+
+By default, `MATLAB.jl` is built using the MATLAB installation with the greatest version number. To specify that a specific MATLAB installation should be used, set the environment variable `MATLAB_ROOT`:
+```julia
+julia> ENV["MATLAB_ROOT"] = "/usr/local/MATLAB/R2021b" # example on a Linux machine
+```
+```julia
+julia> ENV["MATLAB_ROOT"] = raw"C:\Program Files\MATLAB\R2021b" # example on a Windows machine
+```
+Replace the path string with the location of the MATLAB folder on your machine. You need to set the path to the `R20XX` folder, not the `matlab` binary.
+
+If you had the package `MATLAB.jl` already installed and built before changing the environment variable, you will need to rebuild it to apply the change:
+```julia
+julia> using Pkg; Pkg.build("MATLAB")
+```
