Add quotes script and README

README.md

@@ -6,6 +6,14 @@ The issue with Anytype (and Notion) is that there are too many clicks needed.
 While Notion has better automation, I think nothing can beat the functionality of just scripts.
 That and the fact that I want to have all the files as markdown in case I want to search/collect statistics or plots/process with a local llm inspired this project.
 
+**This is mostly AI generated**
+
+## Why use AI for this?
+
+I generally try to avoid AI for personal projects in an attempt to stay mentally sharp and keep my programming skills up. 
+The functionality here are mainly basic automations that aren't very interesting to do by hand.
+Since I want to try and use my time on more interesting problems, I don't feel too bad using AI for these.

 ## Functionality and status
 
 Here is the list of functionality that I'm working towards.
