 Before getting started with these examples, please setup `etcdctl` (with `etcdv3` API) as explained [here](https://coreos.com/etcd/docs/latest/dev-guide/interacting_v3.html). This will help you to put sample keys in your etcd server.
 
-If you prefer, you can use `curl` to populate the `etcd` server, but with `curl` the endpoint URL depends on the version of `etcd`. For instance, `etcd v3.2` or before uses only [CLIENT-URL]/v3alpha/* while `etcd v3.5` or later uses [CLIENT-URL]/v3/* . Also, Key and Value must be base64 encoded in the JSON payload. With, `etcdctl` these details are automatically taken care off.
