 # MkDocs semiliterate Plugin
 
-This plugin for MkDocs is an extension of Allison Thackston's excellent [mkdocs-simple-plugin](https://athackst.github.io/mkdocs-simple-plugin). It allows you to include content from one file into another (via `{! ... !}` syntax), using exactly the same extraction specification as the `simple` plugin already uses for identifying documentation in source files.

-The `simple` plugin goes a long way toward creating a semiliterate programming environment. However, in creating narrative documentation, it's very useful to be able to quote or incorporate content -- whether that be documentation blocks or code examples -- from one file into another. To satisfy that need, this `semiliterate` plugin extends (i.e, literally inherits from) the `simple` plugin and adds a syntax for such inclusion.

However, in creating narrative documentation, it's very useful to be able to quote or incorporate content --- whether that be documentation blocks or code examples or code that itself serves as documentation to avoid repeating information --- from one file into another. To satisfy that need, this `semiliterate` plugin extends (i.e, literally inherits from) the `simple` plugin and adds a syntax for such inclusion.
 
 With a few other small ease-of-use tweaks (documented in the <!-- repo: -->[Usage](http://studioinfinity.org/semiliterate/mkdocs_semiliterate/plugin)<!-- site:[Usage](mkdocs_semiliterate/plugin.md) --> section),
 this extended plugin aims to produce a lightweight but comprehensive semiliterate programming environment. <!-- repo: -->The [documentation site](http://studioinfinity.org/semiliterate)<!-- site:This documentation site --> is, of course, produced by MkDocs using the semiliterate plugin.
 
+## Installation
+
+The mkdocs-semiliterate package which provides the `semiliterate` plugin for MkDocs is available via PyPI:
+
+`python3 -m pip install mkdocs-semiliterate`
+
+or of course if your `pip` is already set up to use a Python 3.5 (or later) installation, just
+
+`pip install mkdocs-semiliterate`
