+title: Use S3 offloader with Pulsar
+sidebar_label: "S3 offloader"
+---
+
+S3 offloader is introduced to serve S3-compatible storage, which means that the storage employs the S3 API as its “language" and applications that speak the S3 API are able to plug and play with S3-compatible storage. 
+
+This chapter guides you through every step of installing and configuring the S3 offloader and using it with Pulsar. 
+
+## Installation
+
+Follow the steps below to install the S3 offloader.
+
+### Prerequisite
+
+- Pulsar: 2.9.2 or later versions
+  
+### Steps
+
+This example uses Pulsar 2.9.2.
+
+1. [Download the Pulsar tarball](getting-started-standalone.md#install-pulsar-using-binary-release).
+
+2. Download and untar the Pulsar offloaders package, then copy the Pulsar offloaders as `offloaders` in the Pulsar directory. See [Install tiered storage offloaders](getting-started-standalone.md#install-tiered-storage-offloaders-optional).
+
+   **Output**
+   
+   As shown from the output, Pulsar uses [Apache jclouds](https://jclouds.apache.org) to support [AWS S3](https://aws.amazon.com/s3/), [GCS](https://cloud.google.com/storage/), [Azure](https://portal.azure.com/#home), and [Aliyun OSS](https://www.aliyun.com/product/oss) for long-term storage.
+
+   ```
+   
+   tiered-storage-file-system-2.9.2.nar
+   tiered-storage-jcloud-2.9.2.nar
+   
+   ```
+
+   :::note
+
+   * If you run Pulsar in a bare-metal cluster, ensure that `offloaders` tarball is unzipped in every broker's Pulsar directory.
+   * If you run Pulsar in Docker or deploy Pulsar using a Docker image (such as K8s and DCOS), you can use the `apachepulsar/pulsar-all` image. The `apachepulsar/pulsar-all` image has already bundled tiered storage offloaders.
+
+   :::
+
+## Configuration
+
+:::note
+
+Before offloading data from BookKeeper to S3-compatible storage, you need to configure some properties of the S3 offload driver. Besides, you can also configure the S3 offloader to run it automatically or trigger it manually.
+
+:::
+
+
+### Configure S3 offloader driver
+
+You can configure the S3 offloader driver in the configuration file `broker.conf` or `standalone.conf`.
+
+- **Required** configurations are as below.
+  
+  | Required configuration | Description | Example value |
