-## Step 1: Install Apache APISIX
+This guide walks you through how you can install and run Apache APISIX in your environment.
 
-Apache APISIX can be installed via the [RPM package](#installation-via-rpm-repository-centos), [Docker image](#installation-via-docker), [Helm Chart](#installation-via-helm-chart) or the [source release package](#installation-via-source-release-package). You can install via any one of these options.
+Refer to the [Getting Started](./getting-started.md) guide for a quick walk-through on running Apache APISIX.
 
-### Installation via RPM Repository (CentOS)
+## Installing etcd
 
-> This installation method is suitable for CentOS 7 and CentOS 8.
+APISIX uses [etcd](https://github.com/etcd-io/etcd) to save and synchronize configuration. Before installing APISIX, you need to install etcd on your machine.
 
-If the official OpenResty repository is **not installed yet**, the following command will help you automatically install both OpenResty and Apache APISIX repositories.
+It would be installed automatically if you choose the Docker or Helm install method while installing APISIX. If you choose a different method or you need to install it manually, follow the steps shown below:

Review Comment:
   We have mentioned that it would be installed for Docker and Helm. Where should we mention etcd installation instead? Just so that users installing via RPM also have it. I was suggested to add etcd installation first [`9cde814` (#6964)](https://github.com/apache/apisix/pull/6964/commits/9cde814e87227de42e0c011306f14f2151b46206#r861433102)
