-A template for modern C++ libraries and projects.
+A template for starting modern C++ libraries and projects.
+Setting up a new C++ project usually requires a significant amount of preparation and boilerplate code.
+Even more so for modern C++ projects with tests and contiguous integration.
+This template is a collection from learnings of previous projects and should allow quick setting up new modern C++ projects.
 
 ## Features
 
 - Modern CMake practices
 - Suited for single header libraries and larger projects
 - Integrated test suite

 - Clone this repo and replace all occurrences of "Greeter" in the [CMakeLists.txt](CMakeLists.txt) with the name of your project
 - Replace the source files with your own
 - For single-header libraries: see the comments in [CMakeLists.txt](CMakeLists.txt)

+## FAQ
+
+  - Can I use this for header-only libraries?
+
+    Yes, however you will need to change the library type to an `INTERFACE` library as documented in the [CMakeLists.txt](CMakeLists.txt).
+
+  - You are using `GLOB` to add source files in CMakeLists.txt. Isn't that evil?
+
+    Glob is considered bad because changes to source files won't be automatically caught by CMakes builders and you will need remember to invoke CMake on any changes.
+    I personally prefer the `GLOB` solution for its simplicity, but feel free to change it to explicitly listing sources.
+
+  - I'm adding external dependencies to my project using CPM. Will this force users to use CPM as well?
+
+    CPM should be mostly invisible for your library users as it's self-contained and dependency free.
+    If problems do arise, they can always opt-out by defining `CPM_USE_LOCAL_PACKAGES`, which will override all calls to `CPMAddPackage` with `find_package`.
+    If you are using `CPMFindPackage` instead of `CPMAddPackage`, CPM will always try to use `find_package` to add packages.
+    This approach should be compatible with any common C++ package manager without any user intervention, however at the cost of reproducible builds.
