 # MD-Bench
-A simple modular molecular dynamics benchmark
+
+A simple, sequential  C version of the Mantevo miniMD benchmark.
+
+## Build
+
+1. Open the `Makefile` and edit the `TAG` value according to the tool chain used. Currently supported is GCC, CLANG (LLVM), and ICC (Intel).
+2. Open and adapt the compiler flags in `<include_<TOOLCHAIN>.mk`, e.g. in `include_ICC.mk` for the Intel tool chain.
+3. Build the binary calling `make`.
+
+You can clean intermediate build results with `make clean`, and all build results with `make distclean`.
+You have to call `make clean` before `make` if you changed the build settings.
+
+## Configuration
+
+Currently all settings are hard-coded in `main.c`.
