 Tip: if you want to exclude all agenda entry types, just set

+* User Defined Functions
+** Function Signature
+User defined functions should:
+
+- Optionally accept one parameter i.e. the =match= variable. The Org agenda dispatch function will call the user-defined function with one parameter representing the =match= component from the agenda definition. In other words, ~(udf/test "Hello")~ in =org-agenda-custom-commands= will result in a function call of ~udf/test~ with an argument of ="Hello"=.
+
+- Prepare a buffer to write the agenda information to using ~org-agenda-prepare~.
+
+- Handle setting a unique buffer name for the cases where =org-agenda-sticky= has a value of =t=.
+
+- Honor the setting of =org-agenda-overriding-header= and insert that text into the agenda buffer. This can be done using the macro ~org-agenda--insert-overriding-header~.
+
+- Insert into the buffer the desired contents, accounting for also setting text properties.
+
+- Call ~org-agenda-finalize~ and ~(setq buffer-read-only t)~
+
+** Example
+This is a simple function to insert notes into the Agenda.
+
+*NOTE: This example is not fully complete as it doesn't respect =org-agenda-sticky=.*
