+Categories:
+
+    Categories are a way to organize videos based on dynamic rules set by the user. Categories are universal (so not per-user).
+    
+    Categories, besides rules, have an optional custom output. This custom output can help users create their
+        desired directory structure.
+
+Rules:
+    A category rule consists of a property, a comparison, and a value. For example, "uploader includes 'VEVO'"
+
+    Rules are stored as an object with the above fields. In addition to those fields, it also has a preceding_operator, which
+        is either OR or AND, and signifies whether the rule should be ANDed with the previous rules, or just ORed. For the first
+        rule, this field is null.
+
+    Ex. (title includes 'Rihanna' OR title includes 'Beyonce' AND uploader includes 'VEVO')

+# A chart can be either an 'application' or a 'library' chart.
+#
+# Application charts are a collection of templates that can be packaged into versioned archives
+# to be deployed.
+#
+# Library charts provide useful utilities or functions for the chart developer. They're included as
+# a dependency of application charts to inject those utilities and functions into the rendering
+# pipeline. Library charts do not define any templates and therefore cannot be deployed.

+# This is the chart version. This version number should be incremented each time you make changes

+# Versions are expected to follow Semantic Versioning (https://semver.org/)
