 ## MIsoEnrich
+### Installation
+This module has some dependencies.
+Python dependencies ([`scipy`](https://github.com/scipy/scipy) and
+[`numpy`](https://github.com/numpy/numpy) are installed automatically via `pip`,
+while the C++ dependencies
+([CppOptimizationLibrary](https://github.com/PatWie/CppNumericalSolvers/tree/master),
+[Eigen](https://eigen.tuxfamily.org/) and
+[JSON for Modern C++](https://github.com/nlohmann/json)) are included as Git
+submodules.
+These need to be fetched first, as shown below:
+```
+$ git clone https://github.com/Nuclear-Verification-and-Disarmament/miso_enrichment.git
+$ cd miso_enrichment
+$ git submodule update --init --recursive  # Download C++ dependencies
+$ python3 install.py  # Install misoenrichment module
+$ misoenrichment_unit_tests  # Run unit tests (optional).
+```
