 [Redis](https://redis.io/) is an open-source, in-memory, data-structure store, with the optional ability to write and persist data to a disk, which can be used as a key-value database, cache, and message broker. Redis features built-in transactions, replication, and support for a variety of data structures such as strings, hashes, lists, sets, and others.
 
+The One-Click App for Redis installs Redis version 7.2.7.

 ## Getting Started after Deployment
 
-### Access the Redis CLI
+### Obtain the Credentials
 
-1.  Log in to your new Compute Instance through [Lish](/docs/products/compute/compute-instances/guides/lish/) or [SSH](/docs/guides/connect-to-server-over-ssh/) using either the `root` user or limited user and the associated password you entered when creating the instance.
+Once the app is deployed, you need to obtain the credentials from the server.
+
+To obtain credentials:
+
+1.  Log in to your new Compute Instance using one of the methods below:
+
+    - **Lish Console**: Log in to Cloud Manager, click the **Linodes** link in the left menu, and select the Compute Instance you just deployed. Click **Launch LISH Console**. Log in as the `root` user. To learn more, see [Using the Lish Console](/docs/products/compute/compute-instances/guides/lish/).
+    - **SSH**: Log in to your Compute Instance over SSH using the `root` user. To learn how, see [Connecting to a Remote Server Over SSH](/docs/guides/connect-to-server-over-ssh/).
+
+1.  Run the following command to access the credentials file:
+
+    ```command
+    cat /home/$USERNAME/.credentials
+    ```
+
+This returns passwords that were automatically generated when the instance was deployed. Save them. Once saved, you can safely delete the file.
+
+
+### Access the Redis CLI
+After you log in and obtain the credentials, you can use the Redis CLI. Redis is configured to require authentication for the default user, and a valid client SSL certificate.
 
-1.  To use the redis-cli, run either of the commands below:
+To access the Redis CLI, run the command:
 
-    - `redis-cli`: This opens the interactive mode where you can type in whichever commands you wish.
-    - `redis-cli [argument]`, where *[argument]* is the argument or command you wish to run. For instance, running `redis-cli ping` should result in the output of `PONG` if redis is configured properly.
+`redis-cli --tls --cacert /etc/redis/ssl/ca/ca.crt --cert /etc/redis/ssl/certs/client1.crt --key /etc/redis/ssl/keys/client1.key.pem -a $REDIS_DEFAULT_USER_PASSWORD`
 
-For more information about the redis-cli and the commands you have available, see [redis-cli, the Redis command line interface](https://redis.io/topics/rediscli).
+This opens the interactive mode where you can type commands. To learn more on the Redis CLI and available commands, see [Redis CLI
