+# Indexer Integration Tests
+
+This package contains integration tests for the indexer. The tests are written in typescript and use the [jest](https://jestjs.io/) testing framework.
+
+They also depend on the `local-network` repository to run a full local network with indexer components.
+
+## Getting started
+
+Dependencies:
+
+- node.js
+- yarn
+- docker
+- docker-compose
+
+## Running the tests
+
+To run the tests, you need to have the `local-network` repository cloned and running. Follow the instructions in the `local-network` repository to set up the local network using docker compose.
