 brew link libdpp
 ```
 
+This command will install libdpp and setup links so it can be used correctly.
+
 You will now be able to use D++ by including its library on the command line:
 
 ```bash
-clang++ -std=c++17 -L/opt/homebrew/lib -I/opt/homebrew/include -ldpp mybot.cpp -o mybot
+clang++ -std=c++17 -I/opt/homebrew/include -ldpp mybot.cpp -o mybot
 ```
 
+\note A crucial part of this command is `-I/opt/homebrew/include`. AppleClang should automatically have `/opt/homebrew/lib` added as a way to detect library (if it doesn't, you can do `-L/opt/homebrew/lib` with this command), however, AppleClang does not auto-detect includes from homebrew. This means, D++ needs you to link the includes folder.

+## Uninstalling & Unlinking
+
+To unlink and uninstall dpp, run
+```bash
+brew unlink libdpp
+brew uninstall libdpp
+```
+
+Then, double check inside `/opt/homebrew/lib` and `/opt/homebrew/include` to make sure that libdpp does not exist. If it does, remove files/folders relating to libdpp.
