+## Fun fact, most of this code is generated entirely using GPT-3.5
+
+## CHATGPT PROMPT 1
+## Explain to me how to parse a conf file in PowerShell.
+
+## AI EXPLAINS HOW... this is important as it invokes reflective thinking.
+## Having AI explain things to us first before asking 
+## your question, significantly improves the quality of the response.
+
+
+### PROMPT 2
+### Okay, using this conf, can you write a powershell script that saves a new value to the global_prep_cmd?
+
+### AI Generates valid code for saving to conf file
+
+## Prompt 3
+### I think I have found a mistake, can you double check your work?
+
+## Again, this is important for reflective thinking, having the AI
+## check its work is important, as it may improve quality. 
+
+## Response: Did not find any errors.
+
+## Prompt 4: I tried this and unfortunately my config file requires admin to save.
+
+## AI Responses solutions
+
+## Like before, I already knew the solution but having the AI
+## respond with tips, greatly improves the quality of the next prompts
+
+## Prompt 5 (Final with GPT3.5): Can you make this script self elevate itself.
+## Repeat the same prompt principles, and basically 70% of this script is entirely written by Artificial Intelligence. Yay!
+
+## Refactor Prompt (GPT-4): Please refactor the following code, remove duplication and define better function names, once finished you will also add documentation and comments to each function.
