+# InfiniSim
+
+Build environment for [InfiniSim](https://github.com/InfiniTimeOrg/InfiniSim).
+
+## Building the Project
+
+Build instructions:
+
+```
+$ nix-shell
+$ cmake -DWITH_PNG=OFF -S . -B build
+$ cmake --build build -j6
+```
+
+By default the build uses a version of the [InfiniTime sources](https://github.com/InfiniTimeOrg/InfiniTime) in `./InfiniTime` as git submodule. You might want to delete this submodule and use a symlink to a local version of InfiniTime or update the submodule to track your own fork of InfiniTime.
