-otherwise it is called an out-of-tree build.
+files or makefiles for your development environment.  CMake needs two paths for
+this:
 
-One of several advantages of out-of-tree builds is that you can generate files
-and compile for different development environments using a single source tree.
+ - the path to the root directory of the GLFW source tree (not its `src`
+   subdirectory)
+ - the path to the directory where the generated build files and compiled
+   binaries will be placed
 
-@note This section is about generating the project files or makefiles necessary
-to compile the GLFW library, not about compiling the actual library.
+If these are the same, it is called an in-tree build, otherwise it is called an
+out-of-tree build.
+
+Out-of-tree builds are recommended as they avoid cluttering up the source tree.
+They also allow you to have several build directories for different
+configurations all using the same source tree.
+
+A common pattern when building a single configuration is to have a build
+directory named `build` in the root of the source tree.
