 # RailsLite
+
+RailsLite is a lightweight version of Ruby-on-Rails built from scratch, featuring some of the basic functionality from Rails.
+
+This particular construction includes a lightweight version of Active Record that includes model associations and table modification/lookup methods.
+

+-Automated table naming based on Active Record conventions.
+-Getter and setter methods for table columns.
