+## I have trouble setting up SFML?!
+
+The official [SFML Tutorials](https://www.sfml-dev.org/tutorials/latest/#getting-started) feature detailed setup descriptions for some compilers.
+
+By far the simplest setup, with cross-platform guarantees, is to use the [SFML CMake Template](https://github.com/SFML/cmake-sfml-project).
+Follow the instructions in the README.
+
+Don't forget, SFML is just like any other C++ library:
+
+-   Tell the compiler where to find the SFML headers
+-   Tell the linker which libraries to link
+-   Make sure to use the same runtime library as was used for SFML
+
+## I don't understand how to use SFML?!
+
+The [official tutorials](https://www.sfml-dev.org/tutorials/latest/) and [documentation](https://www.sfml-dev.org/documentation/latest/) provide a lot of information to understand the ins and outs of SFML.
+
+## I have a question!
