-Installation
-============
-
-Until we get binary wheels published (`#9 <https://github.com/JamesTheAwesomeDude/pypqc/issues/9>`_), you must:
-
-1. Install a C compiler
-
-2. Apply OS-specific fixes:
-
-   - If you're on Windows, create a folder ``C:\temp`` and then run ``set "TMPDIR=C:\temp"``. (Workaround for `#14 <https://github.com/JamesTheAwesomeDude/pypqc/issues/14>`_)
-
-   - If you're on Linux, install the Python development headers.
-
-3. Run ``pip install pypqc``
-
 Usage
 =====
 
+Simply install from PyPI with ``pip install pypqc``, or see "Development" below
+if you want to tinker on the codebase!
