 ## Prerequisites
 
 * Install [`etcd` and `etcdctl`](https://etcd.io/docs/v3.6/install/)
+* A running etcd cluster (see [How to Set Up a Demo etcd Cluster](/docs/v3.6/tasks/operator/how-to-setup-cluster/))
 
 ## Creating a lock
 
-`lock` for distributed lock:
+Acquire a lock with a specified name:
+```shell
+etcdctl --endpoints=$ENDPOINTS lock mutex1
+```
 
-![08_etcdctl_lock_2016050501](https://storage.googleapis.com/etcd/demo/08_etcdctl_lock_2016050501.gif)
+The lock will be held until the command is terminated with `Ctrl+C`.
 
+### Lock with command execution
+
+You can also execute a command while holding the lock:
 ```shell
-etcdctl --endpoints=$ENDPOINTS lock mutex1
+etcdctl --endpoints=$ENDPOINTS lock mutex1 echo "Lock acquired"
 ```
 
-### Options
-- endpoints - defines a comma-delimited list of machine addresses in the cluster.
-- ttl - time out in seconds of lock session.
+When using this form, the lock is automatically released after the command completes.
+
+### Visual demonstration

+
+## Options
+
+- `--endpoints` - Comma-delimited list of etcd cluster endpoints (default: `http://127.0.0.1:2379`)
+- `--ttl` - Time to live in seconds for the lock session (default: 60)
+
+## Releasing a lock
+
+Locks are released in the following ways:
+
+- **Manual release**: Press `Ctrl+C` to terminate the etcdctl lock command
+- **Automatic release**: When executing a command with the lock, it is released after the command completes
+- **TTL expiration**: The lock automatically expires after the TTL period if not renewed
