 ### Installation
 
-_You will need to install these utilities in order to use them. Your package
-manager may already have them. Below are the package names for each package manager, if available:_
+Use these commands to install some or all of the linters used in this project:
 
-* `apt install clang clang-format clang-tidy uncrustify cppcheck iwyu` [1] [2]
-* `yum install llvm uncrustify cppcheck iwyu` [2]
-* `brew install llvm oclint uncrustify cppcheck include-what-you-use` [3]
-* `choco install llvm uncrustify cppcheck inlcude-what-you-use` [4]
+* Linux/Macos
+    * `brew install llvm uncrustify cppcheck include-what-you-use`
+    * `pip install cpplint`
+    * `brew install oclint` (macos), see note below for oclint on Linux
+* Windows
+    * `choco install llvm uncrustify cppcheck inlcude-what-you-use` [4]
+    * `pip install cpplint`
 
-cpplint can be installed everywhere with `pip install cpplint`.
+While it's possible to use other package managers to install these utilities on Linux, I recommend
+using brew to avoid dependency issues between llvm and linters that use it.
