+[`parachains-integration-tests`](https://github.com/paritytech/parachains-integration-tests) is a tool designed to test interactions between Substrate based blockchains.
+
+Is used here to develop tests rapidly describing them in a YAML file.
+
+# Setup
+
+Install `parachains-integration-tests` into your system:
+```
+$ yarn global add ts-node
+
+$ yarn global add @parity/parachains-integration-tests
+```
+
+Review the [Run a local network](https://github.com/paritytech/extended-parachain-template#%EF%B8%8F-run-a-local-network) to set up Zombienet in your system.
+
+Create a `bin` directory into the root of this repository and place the following binaries inside of it:
+- `polkadot` (which you can download from [the releases](https://github.com/paritytech/polkadot/releases))
+- `polkadot-parachain` (which you will build from [cumulus](https://github.com/paritytech/cumulus))
+
+Use the following command in the root of this repository to build the node:
+
+```sh
+cargo build --release
+```
+
+# Usage
+
+Please refer to the [project's `README.md`](https://github.com/paritytech/parachains-integration-tests#how-to-use) for an extensive description of how to write YAML test files and how to execute tests.
