 Installation
 ============
 
-Mopactools will soon be available on PyPI and conda-forge, which will handle all aspects of the installation. In particular,
-they will package copies of the MOPAC shared library for convenient use within the Python software ecosystem.
+Mopactools is available on PyPI and can be installed using a standard ``pip install mopactools``. The PyPI distribution
+includes a copy of the MOPAC shared library. Mopactools will also be available on the conda-forge channel of the Conda package
+manager in the near future.
 
-Otherwise, mopactools can be installed locally using a standard ``pip install .`` command in the root of the source directory.
-For mopactools to function correctly, it must be able to find the MOPAC shared library in the system path or in the ``lib``
-subdirectory of the installed package directory. If a copy of the MOPAC shared library is placed into the ``lib`` subdirectory
-of the source package, then the ``pip install .`` command will create another copy in the installed package directory.
