+# Welcom to the Test of MDAI Documentation Via Jekyll and GitPages!
+
+This is a test of what can be used to generate the MDAI project documentation.
+
+This uses the GitHub Way of generating documentation, with local testing.
+
+Local testing means installing Jekyll (and all of the Ruby stuff)
+to build the site locally for a sanity check. Then push to the repo
+to have GitHub actions build the site on the remote.
+
+*Note:* The GitHub actions can take a few minutes to build the site.
+
+Jekyll supports the Liquid templating language.
+
+We're also trying out the Just the Docs theme instead of the built-in
+Jekyll theme or any of the other "approved" Jekyll. Just the Docs is 
+designed for documentation, is well-supported, and designed to work
+in Jekyll with GitHub pages.
