+# Test Helpers
+
+This directory hosts reusable utilities for exercising storage implementations in end-to-end and compatibility testing scenarios. Each helper is maintained as its own Go module so it can be consumed independently.
+
+## Available helpers
+
+- **Redis** (`testhelpers/redis`): Spins up Redis with Testcontainers and exposes convenience functions for running integration tests against Redis-backed storage implementations.
+- **Test Compatibility Kit (TCK)** (`testhelpers/tck`): Provides a reusable test suite that validates any `storage.Storage` implementation for correctness and API parity.
+
+## Running tests locally
+
+From the repository root, run tests for a helper by changing into its directory and executing `go test`:
+
+```sh
+cd testhelpers/redis
+go test ./... -v -race
+```
+
+The helpers rely on Docker via [testcontainers-go](https://github.com/testcontainers/testcontainers-go), so ensure Docker is available and running before executing the tests.

+# Redis Test Helper
+
+This module provides utilities for starting a disposable Redis instance with [testcontainers-go](https://github.com/testcontainers/testcontainers-go). It is useful for integration tests against storage implementations that rely on Redis.
+
+## Features
+
+- Starts Redis containers with optional TLS, host/port, address, or URL connection helpers.
+- Supports container reuse via `WithReuse` for faster local iteration.
+- Exposes connection details (URL, host/port, addresses, TLS config) through the returned `Container` struct.
+
+## Usage
+
+Import the helper and start a Redis container in your tests:
+
+```go
+import (
+    testredis "github.com/klauspost/storage/testhelpers/redis"
+)
+
+func TestExample(t *testing.T) {
+    ctr := testredis.Start(t, "redis:7-alpine")
+
+    // Use ctr.URL, ctr.Host/Port, or ctr.TLSConfig in your test code.
+}
+```
+
+## Running locally
+
+From the repository root, execute the helper's tests:
+
+```sh
+cd testhelpers/redis
+go test ./... -v -race
+```
+
+Docker must be available and running for the tests to start Redis containers.
