 ### Creating secrets
 
-To create a parameter, you can do it via the [AWS SSM console](https://console.aws.amazon.com/systems-manager/parameters) or the [Bref Dashboard](https://dashboard.bref.sh/):

+        If you have **not** deployed the application yet, go to the root "Secrets" section in Bref Cloud and create a new secret there ([bref.cloud/secrets/create](https://bref.cloud/secrets/create)). Provide the target application and environment name when creating the secret.
 
-You can also do it in the CLI via the following command:
+        If you have already deployed the application, open the application in Bref Cloud, go to a specific environment, and create a new secret under the "Secrets" tab:
 
-```bash
-aws ssm put-parameter --region us-east-1 --name '/my-app/my-parameter' --type String --value 'mysecretvalue'
-```

-On Windows, the first part of the path needs to be double slashes and all subsequent forward slashes changed to backslashes:
+        You can also run the `bref secret:create` command in your terminal:
 
-```bash
-aws ssm put-parameter --region us-east-1 --name '//my-app\my-parameter' --type String --value 'mysecretvalue'
-```
+        ```bash
+        bref secret:create

-SSM also allows to store a SecureString parameter, which is encrypted with AWS KMS. To use a SecureString, simply change the `--type` argument to `--type SecureString`. Bref takes care of decrypting the value.
