 To start posting messages securely we need the following:
 
-| Key | Description |
-| --- | --- |
-| Module Handle | Unique handle of the micro module. This will be provided by the service provider. |
-| Secret Key | Secret Key is required for encryption. Secret Key should be generated on the Appsfly publisher dashboard. |
-| App Key | Application key to identify the publisher instance. |
 
-You will have to generate a checkSum from the parameters, headers with the secret key provided by appsfly.io.

-## Configuration
-Configure the app using the following parameters:
 
-* REPO_URL - currently "https://microapps.appsfly.io"
-* SECRET_KEY - generated secret key, contact [email protected] for a secret key
-* APP_KEY - assigned Application key. Eg: "92ae2562-aebc-468f-009e-aa300d9d39b1"
+  **NOTE:** You will have to generate a checkSum from the parameters, headers with the secret key provided by appsfly.io.

+# Integration options  
+### Option 1: Package
 The SDK can be included to handle the encryption and decryption along with checkSum generation and verification.
 You can use it to avoid boiler plate code. If not, you can use the api endpoint.
