 Installation
 *************
 
-Installation is currently supported on Windows, Mac. No special requirements or prerequeisites are necessary.
+Installation using pre-built packages are currently supported on Windows, Mac but excludes Linux because pre-built
+packages are unsupported via PyPi. Otherwise, no special requirements or prerequisites are necessary.
 
 .. code:: bash
 
     conda install -c numpy
     pip install numpy
 
-Installation of pycork can then be performed using pre-built python packages using the PyPi repository.
+Installation of `pyclipr` can then be performed using the pre-built python packages using the PyPi repository.
 
 .. code:: bash
 
     pip install pyclipr
 
-Alternatively, pyclipr may be compiled directly from source within the python environment.
-Currently the prerequisites are the a compliant c++ build environment include CMake build system (>v3.15) and the
-availability of a compiler with c++17 compatibility.  Currently the package has been tested on Windows 10, using VS2019. E
+Alternatively, pyclipr may be compiled directly from source within the python environment. Currently the prerequisites
+are the a compliant c++ build environment include CMake build system (>v3.15) and the availability of a compiler with
+c++17 compatibility.  Currently the package has been tested built using Windows 10, using VS2019 and Mac OSX Sonoma.
 
-Ensure that you perform the recurisve submodule when initialising the repoistory.
+Firstly, clone the PyClipr repository whilst ensuring that you perform the recurisve submodule when initialising
+the repoistory. This ensures that all dependencies (pybind, pyclipr, eigen, fmt) are downloaded into the source tree.
