 Confused about the display of missing parts in the console?
 It's actually quite easy to read and I'll show you how its done! :D
 
-Let's take the for the following missing path:
+Missing parts are written in this format right here: xyz.zyx.idk
+A more befitting example would be something like:
 --> test-feature.enabled
 
 In the config.yml, this would look like this:
 
 
-test-feature:
-  enabled: true

-Now another example with something more fitting to your case:

+Now that we know how things from the missing parts look like in the config.yml, let's go over to the more important part.
+Inserting the missing parts to your current config.yml. But how and what exactly?

 Well, it's actually quite easy. Just take a look on what is missing.
 If PAT says, something like this is missing:
 - test-feature.enabled

 Then this basically just means, that the entire section for "test-feature" is missing.
 In other words, check the "comparable-config.yml" and look for the "test-feature" section.

 Just copy the entire thing and paste it somewhere in the config.yml.
 Once you've reloaded the plugin then, using "/(b)pat reload", everything should work fine.

+Here's a more close to your case example. Let's say your config.yml looks like this:
+
+    handle-through-proxy:
+      ...
+
+    turn-blacklist-to-whitelist: true
+
+    custom-protocol-ping:
+      ...
+
+
+and now let's say PAT says that "base-command-case-sensitive" is missing.
+Then this would be what PAT is looking for as solution:
+
+    handle-through-proxy:
+      ...
+
+    turn-blacklist-to-whitelist: true
+
+    base-command-case-sensitive: true/false
+
+    custom-protocol-ping:
+      ...
+
+
+On how exactly it needs to be implemented can be seen in the comparison-config.yml file,
+as this is the original version which would be generated by default.
