+## Using Your Library
+
+To consume a library using cpp-library, use [CPM](https://github.com/cpm-cmake/CPM.cmake) or `FetchContent`.
+
+```cmake
+CPMAddPackage("gh:your-org/[email protected]")
+target_link_libraries(executable your_namespace::your-library)
+```
+
+### Target Naming
+
+For `project(your-library)`, `cpp_library_setup` will create a target called `your-library`.
+
+The utility will additionally create an alias target based on the `NAMESPACE` option, `your_namespace::your-library`.
+
+If your project name starts with the namespace followed by a dash, the namespace in the project ma,e is stripped from the alias target:
+
+```cmake
+... # skip skip
+project(namespace-library)
+... # skip skip skip
+
+cpp_library_setup(
+  NAMESPACE namespace
+  ...
+)
+```
+
+Results in  `namespace-library` and `namespace::library`.
+
 ### Prerequisites
 
 - **CPM.cmake**: Must be included before using cpp-library
