 ## Building/Running
 
 RustMP requires the following dependencies to run:
+- `hwloc2-v2.2.0`: C HWLoc wrapper used for NUMA aware process pinning
+- `lazy_static-v1.4.0`: Lazy static macro used for delayed singleton init
+- `num-v0.3`: Needed to run the Rust factorial benchmarks
 - `rand-v0.8.3`: Random number generation used for benchmarking examples
 - `rayon-v1.5.0`: Rayon parallel iterator library used in RustMP/Rayon..
