+# Squib Samples
+
+In here we have a massive library of Squib samples. We try to exercise as many options as possible here as these samples also serve as Squib's regression test suite.
+
+If you have one to contribute, file an issue!
+
+# What's with the underscores?
+
+Normally you don't start a filename with an underscore (e.g. `_text.rb`), but to make it easier to find the code itself on GitHub, we've renamed the files so they sort to the top of the list.
