+# Introduction
+
+This directory contain contract tests that exist to prevent regressions. They cover:
+* [OpenTelemetry semantic conventions](https://github.com/open-telemetry/semantic-conventions/).
+* Application Signals-specific attributes.
+
+# How it works?
+
+The tests present here rely on the auto-instrumentation of a sample application which will send telemetry signals to a mock collector. The tests will use the data collected by the mock collector to perform assertions and validate that the contracts are being respected.
+
+# Types of tested frameworks
+
+The frameworks and libraries that are tested in the contract tests should fall in the following categories (more can be added on demand):
+* http-servers - applications meant to test http servers (e.g. Django).
+* http-clients - applications meant to test http clients (e.g. requests).
+* aws-sdk - Applications meant to test the AWS SDK (e.g. botocore).
+* database-clients - Applications meant to test database clients (e.g. psychopg2).
+
+When testing a framework, we will create a sample application. The sample applications are stored following this convention: `contract-tests/images/applications/<framework-name>`.
+
+# Adding tests for a new library or framework
+
+The steps to add a new test for a library or framework are:
+* Create a sample application.
+    * The sample application should be created in `contract-tests/images/applications/<framework-name>`.
+    * Implement a `pyproject.toml` (to ensure code style checks run), `Dockerfile`, and `requirements.txt` file. See the `requests` application for an example of this.
+* Add a test class for the sample application.
+    * The test class should be created in `contract-tests/tests/amazon/<framework-name>`.
+    * The test class should extend `contract_test_base.py`
+
+# How to run the tests locally?
+
+Pre-requirements:
+* Have `docker` installed and running - verify by running the `docker` command.
+
+Steps:
+* From `aws-otel-python-instrumentation` dir, execute:
+```sh
+./scripts/build_and_install_distro.sh
+./scripts/set-up-contract-tests.sh
+pytest contract-tests/tests
+```
