+## Overview
+
+This is the repository for the code accompanying my bachelor project. The
+source code is located in the `src/` directory. The version of MP-SPDZ used is
+v0.3.6.
+
+The `ansible/` directory contains an Ansible playbook that provisions three
+servers ready to use with MP-SPDZ. It also contains a `Vagrantfile` that can be
+used to provision three virtual machines using VirtualBox.
+
+## How to run computation locally
+
+This guide assumes an Ubuntu 22.04 environment and is only tested with such
+system. Make sure to have GNU Make installed.
+
+1. Clone this repository and run `git submodule update --init` to clone MP-SDPZ
+   as a submodule.
+2. Navigate to `src/`.
+3. Run `make -j$(nproc)` to install dependencies and compile MP-SPDZ.
+4. Run `./gen_data.sh 50` to randomly generate data for the computation.
+5. Run `./run.sh` to run the computation with three MPC parties locally in the
+   background. The computation will print output to `src/out-p${n}.txt` (`n =
+   party`, `./run.sh -k` to kill computation).
+
+### Summary
+
+```sh
+git submodule update --init
+cd src/
+make -j$(nproc)
+./gen_data.sh 50
+./run.sh
