+# OpenTelemetry ioredis Instrumentation for Node.js
+[![Gitter chat][gitter-image]][gitter-url]
+[![dependencies][dependencies-image]][dependencies-url]
+[![devDependencies][devDependencies-image]][devDependencies-url]
+[![Apache License][license-image]][license-image]
+
+This module provides automatic instrumentation for [`ioredis@^4.14.0`](https://github.com/luin/ioredis).
+
+For automatic instrumentation see the
+[@opentelemetry/node](https://github.com/open-telemetry/opentelemetry-js/tree/master/packages/opentelemetry-node) package.
+
+## Installation
+
+```
+npm install --save @opentelemetry/plugin-ioredis
+```
+
+### Supported Versions
+ - `>=4.14.0`
+
+## Usage
+
+OpenTelemetry IORedis Instrumentation allows the user to automatically collect trace data and export them to the backend of choice, to give observability to distributed systems when working with [ioredis](https://www.npmjs.com/package/ioredis).
+
+To load a specific plugin (**ioredis** in this case), specify it in the Node Tracer's configuration
+```js
+const { NodeTracer } = require('@opentelemetry/node');
+
+const tracer = new NodeTracer({
+ plugins: {
+ ioredis: {
+ enabled: true,
+ // You may use a package name or absolute path to the file.
+ path: '@opentelemetry/plugin-ioredis',
+ }
+ }
+});
+```
+
+To load all the [supported plugins](https://github.com/open-telemetry/opentelemetry-js#plugins), use below approach. Each plugin is only loaded when the module that it patches is loaded; in other words, there is no computational overhead for listing plugins for unused modules.
+```javascript
+const { NodeTracer } = require('@opentelemetry/node');
+
+const tracer = new NodeTracer();
+```
