+description: Get etcd up and running in less than 5 minutes!
+---
+
+Follow the instructions below to locally install, run, and test a simple
+single-member cluster of etcd.
+
+## Install etcd
+
+Set the environment variables to help with the commands that follow:
+
+```
+ETCD_VER={{< param git_version_tag >}}
+
+GOOGLE_URL=https://storage.googleapis.com/etcd
+GITHUB_URL=https://github.com/etcd-io/etcd/releases/download
+```
+
+Download and install etcd from pre-built binaries:
+
+On Linux
+
+```
+DOWNLOAD_URL=${GITHUB_URL}
+
+rm -f /tmp/etcd-${ETCD_VER}-linux-amd64.tar.gz
+rm -rf /tmp/test-etcd
+mkdir -p /tmp/test-etcd
+
+curl -L ${DOWNLOAD_URL}/${ETCD_VER}/etcd-${ETCD_VER}-linux-amd64.tar.gz -o /tmp/etcd-${ETCD_VER}-linux-amd64.tar.gz
+
+tar xzvf /tmp/etcd-${ETCD_VER}-linux-amd64.tar.gz -C /tmp/test-etcd --strip-components=1
+```
+
+On macOS
+
+```
+DOWNLOAD_URL=${GOOGLE_URL}
+
+rm -f /tmp/etcd-${ETCD_VER}-darwin-amd64.zip
+rm -rf /tmp/etcd-${ETCD_VER}-darwin-amd64
+rm -rf /tmp/test-etcd
+mkdir -p /tmp/test-etcd
+
+curl -L ${DOWNLOAD_URL}/${ETCD_VER}/etcd-${ETCD_VER}-darwin-amd64.zip -o /tmp/etcd-${ETCD_VER}-darwin-amd64.zip
+
+unzip /tmp/etcd-${ETCD_VER}-darwin-amd64.zip -d /tmp
+ln -s /tmp/etcd-${ETCD_VER}-darwin-amd64/* /tmp/test-etcd
+```
+
+{{% alert title="Note" color="info" %}}
+To work with the latest version, learn how to [build from the main branch](/docs/{{< param version >}}/dl-build/#build-the-latest-version).
+{{% /alert %}}
+
+## Launch etcd
+
+Go to the download directory and launch etcd:
+
+```
+$ cd /tmp/test-etcd
+$ ./etcd
+{"level":"warn","ts":"2021-05-12T11:03:01.247-0700","caller":"etcdmain/etcd.go:119","msg":"'data-dir' was empty; using default","data-dir":"default.etcd"}
+⋮
+```
+
+## Set and get a key
+
+From another terminal, use etcdctl to set a key:
+
+```
+$ cd /tmp/test-etcd
+$ ./etcdctl put greeting "Hello, etcd"
+OK
+```
+
+Now that a key has been set, retrieve it:
+
+```
+$ ./etcdctl get greeting
+greeting
+Hello, etcd
+```
+
+## Next steps
+
+Now it's time to dig into the full etcd API and other guides.

+- Set up a [multi-machine cluster][clustering].
+- Learn the [config format, env variables and flags][configuration].
+- Find [language bindings and tools][integrations].
+- Use TLS to [secure an etcd cluster][security].
