 Now that you have the script downloaded, launch the script, and go through the  
 [first time setup](#First-Time-Setup).
 
-### First Time Setup
+## Customization
+
+### 1. Ease of use (Part 1)
+
+Now that you have launched the script, you can safely delete the downloaded file.  
+You should now set it up for better ease of use.
+
+### 2. Ease of use (Part 2, warning for setting up auto-run)
+
+For launching the script easier, I included 2 (DANGEROUS!) methods that you can use.  
+NOTE: You use these methods at your own risk, as they involve basic modification of the system.  
+I have tested both, and I can confirm that they do not break anything (major).
+The safer option is likely the best one to go with, as it involves launching the script  
+via a command, rather than launching automatically whenever you load a Command Prompt window.  
+That more dangerous option will break any other batch scripts that run.
+
+### 3. Ease of use (Part 3, actually setting it up)
+
+If this is your first time launching the program, you can set it up from the first time setup.  
+For the rest of you who have been using this program already, you can go to Settings (8) and  
+Auto-Run (3) to enter the auto-run settings menu.
+
+### 4. Ease of use (Part 3, actually setting it up 2)
+
+Now that you are in that menu, I highly recommend that you choose the safer option,  
+as this involves adding it to the system PATH, which is 10x safer than the more dangerous option.  
+Anyways, to use the safer option, press <kbd>S</kbd>, to use the more dangerous option (and please don't),  
+press <kbd>D</kbd>.
