+title: Getting started with etcdctl
+weight: 3250
+description: "etcdctl: a command line tool for interacting with the etcd server"
+---
+Users mostly interact with etcd by putting or getting the value of a key. This page describes how to do that by using etcdctl, a command line tool for interacting with etcd server and also points to various links for more detailed explanations on important/advanced topics. The concepts described here should apply to the gRPC APIs or client library APIs.
+
+The API version used by etcdctl to speak to etcd may be set to version `2` or `3` via the `ETCDCTL_API` environment variable. By default, etcdctl on master (3.4) uses the v3 API and earlier versions (3.3 and earlier) default to the v2 API.
+
+Note that any key that was created using the v2 API will not be able to be queried via the v3 API.  A v3 API ```etcdctl get``` of a v2 key will exit with 0 and no key data, this is the expected behaviour.
+
+
+```bash
+export ETCDCTL_API=3
+```
+
++ To get started with installing and setting up an etcd cluster, follow the instructions in **[Install]( ../../../docs/v3.5/install)** page of the documentation.
+
++ To configure local etcd cluster for testing and development purposes, visit **[Set up a local cluster](../../../docs/v3.5/dev-guide/local_cluster)** for more details.
+
+Once the etcd cluster is set up and running, it might be a good option to know the versions of etcdctl and Server API in order to find the appropriate commands to be used for performing various operations on etcd.
+
+Here is the command to find the versions:
+
+```bash
+$ etcdctl version
+etcdctl version: 3.1.0-alpha.0+git
+API version: 3.1
+```
+To **write a key** to be stored into the etcd cluster, below is the command to set the value of a key `foo` to `bar`:
+
+```bash
+$ etcdctl put foo bar
+OK
+```
+
+Similarly, to **read the values of keys** from an etcd cluster, here is the command to read the value of the key `foo`:
+
+```bash
+$ etcdctl get foo
+foo
+bar
+```
+
+To know more about all the functionalities that etcdctl offers, visit **[Interacting with etcd](../../../docs/v3.5/dev-guide/interacting_v3)** for more details.
