# Documentation

etcd is a distributed key-value store designed to reliably and quickly preserve and provide access to critical data. It enables reliable distributed coordination through distributed locking, leader elections, and write barriers. An etcd cluster is intended for high availability and permanent data storage and retrieval.

## Getting started

New etcd users and developers should get started by [downloading and building][download_build] etcd.

## Developing with etcd

The easiest way to get started using etcd as a distributed key-value store for your applications is to [set up a local cluster][local_cluster].

 - [Setting up local clusters][local_cluster]
 - [Interacting with etcd][interacting]
 - [API references][api_ref]

## Operating etcd clusters

Administrators who need to create reliable and scalable key-value stores for the developers they support should begin with a [cluster on multiple machines][clustering].

 - [Setting up clusters][clustering]
 - [Configuration][conf]
 - Security
 - Monitoring
 - [Maintenance][maintenance]
 - [Disaster recovery][recovery]
 - Performance
