 This is a Julia wrapper of the PyX plotting and TeX graphics library from
 Python.

-## Install
+There are many (ported) examples in the ./examples/ directory of this
+repository. See the Python PyX upstream documentation for example outputs:
+
+    http://pyx.sourceforge.net/
+
+## Dependencies and Python Version
+
+You'll obviously need the underlying Python PyX library installed, plus any
+dependencies (eg, LaTeX and Ghostscript). These are pretty huge and complex
+packages to install! Use something like Debian's `apt` or Homebrew on OS X. No
+idea how to get this set up on Windows or other platforms.
+
+*NOTE:* PyX versions starting with 0.13 are Python3-only. PyX versions 0.12.1
+and earlier are Python2-only. This split happened back in 2013. This wrapper
+will work with versions on either side of the split, but the newer versions
+(starting with PyX 0.14) support SVG and newer features. Unfortunately,
+switching Julia's PyCall wrapper from Python2 to Python3 is all or nothing.
+Careful! If you decide to do this, run:
+
+    julia> ENV["PYTHON"] = "/usr/bin/python3" # Or your local full path
+    julia> Pkg.build("PyCall")
 
-There are no installation instructions.
+### Install
+
+This package is not (yet) listed in the official Julia MANIFEST.jl index, so
+you'll need to install it "unregistered" style:
+
+    julia> Pkg.clone("https://github.com/bnewbold/PyX.jl")
+    julia> using PyX
