+# What is this?
+This whole tool is a basic front end for using Python's `matplotlib` in a
+moderately interactive and robust manner to do MATLAB-like number crunching and
+(more critically) plot generation for papers.
+
+## MATLAB Soapbox Explanation
+While MATLAB has routines to save figures, the graphics back-end routinely runs
+into issues with NVIDIA GPU based systems, and I'm sick and tired of being tied
+to a tool that has a heavy resource footprint and only moderate documentation.
+The licensing restrictions (though not fundamentally debilitating) are a
+secondary reason I'm moving away from MATLAB. Finally, as I expect to graduate
+soon, the $50 (or $130 for my toolboxes) annual cost is going to rise to a
+debilitating point for things as mundane as personal projects. So I might as
+well kick an expensive habit while it's easy to fall back when needed.
+
+# Resources
+There are a few tricks to help configuring `matplotlib`. I'll update this
+document to describe the commands and tools to help decipher the information
+required to produce plots in a repeatable and tidy way.
+
+## 1. Plot Defaults
+Plot defaults are managed by the `matplotlib`
+
+## 2. Font Selection
+```python
+import `matplotlib`.font_manager
+print(matplotlib.font_manager.fontManager.afmlist)
+print(matplotlib.font_manager.fontManager.ttflist)
+```
+
+I search for fonts using the following method:
+```
+import matplotlib.font_manager as FM
+import re
+
+fcFontList = FM.get_fontconfig_fonts()
+# Search only for fonts that have name matches similar to this
+fontsDesired = ['Helvetica', 'Times', 'Arial']
+fontsDesiredRe = re.compile('|'.join(fontsDesired), flags=re.IGNORECASE)
+# Create a unique set of the fonts selected out of all of the system fonts
+fontsAvailable = set([FM.FontProperties(fname=fcFont).get_name()\
+	for fcFont in fcFontList if fontsDesiredRe.search(fcFont) != None])
+
+```
+
+[matplotlib docs](https://matplotlib.org/api/font_manager_api.html)
+
+## 3. 
+
+# TODO
+* make pySmithPlot a git sub-module
+* think of a smarter way to refactor things (this is an ever evolving goal)
