+# Dodge the Creeps!
+
+This is an implementation of the Godot "Dodge the Creeps!" tutorial game using godot-cpp 3.2.
+
+## Running the packaged version
+
+After downloading and extracting the package, you will most likely need to mark the `Dodge the Creeps!.x86_64` file, located in the folder `Dodge the Creeps! (Linux 64)` as executable.
+Afterwards, simply launch the executable file.
+
+## Compiling
+
+Before you can use the "script" implementations in Godot, you will need to compile the shared library.
+You will need the following:
+
+* Conan
+* CMake >= 3.14
+* GCC >= 9.2
+
+If you have installed the required tools, issue the following commands from the root folder of your clone:
+
+```
+$ cmake -S . -B build
+$ cmake --build build
+```
+
+If the compilation succeeds, you can now open the project in the Godot editor.
+
+## Packaging
+
+To export the Godot project, simply issue the following commands from the root folder of your clone:
+
+```
+mkdir -p pkg
+godot --path godot --export "Linux" '../pkg/Dodge the Creeps!.x86_64'
+```
+
+You will be left with an executable and the "script" library.
+To further bundle them, use the following command from the root folder of your clone:
+
+```
+tar -czf 'Dodge the Creeps! (Linux 64).tzst' --transform 's/pkg/Dodge the Creeps! (Linux 64)/' pkg/*
+```
