+## Pre-requisites
+
+The build & test instructions below should work out of the box with Node ^14.18.0. (Please note that it needs Node 14 specifically, and will NOT work with Node 16 or higher. Minor version should be at least 18).
+
+## Clone
+
+This repository uses git submodules; use `--recurse-submodules` option when cloning. For example, using https:
+
+```bash
+$ git clone --recurse-submodules https://github.com/balancer-labs/balancer-v2-monorepo.git

 You can see a sample report of a test run [here](./audits/test-report.md).
 
+### Foundry (Forge) tests
+
+To run Forge tests, first [install Foundry](https://book.getfoundry.sh/getting-started/installation). The installation steps below apply to Linux or MacOS. Follow the link for additional options.
+
+```bash
+$ curl -L https://foundry.paradigm.xyz | bash
+$ source ~/.bashrc # or open a new terminal
+$ foundryup
+```

+Then, to run tests in a single package, run:
+```bash
+$ cd pkg/<package> # e.g. cd pkg/v2-vault
+$ yarn test-fuzz
+```
