 ## Salesforce Functions
 
-Use the Salesforce Functions features in VS Code to build event-driven, elastically scalable apps and experiences. You can create and test functions against sample payloads locally in VS Code.
+The Salesforce Extensions pack no longer support Salesforce Functions. We're listing equivalent CLI commands that you can use to create and start a  Function.
 
 ### Create Function
 
-Run `SFDX: Create Function` to create a Salesforce Function in Javascript, Typescript, or Java in a Salesforce DX project.
-
-This command creates a new directory named after your Function name and all the supporting files.
-
-- VS Code creates the basic scaffolding that contains files with some rudimentary, boilerplate code and supporting metadata.
-- The `package.json` file contains information about dependencies.

+See [generate function](https://developer.salesforce.com/docs/atlas.en-us.sfdx_cli_reference.meta/sfdx_cli_reference/cli_reference_generate_commands_unified.htm#cli_reference_generate_function_unified). 
 
 ### Start Function
 
-Run `SFDX: Start Function` to run the function locally.
-
-### Invoke Function
-
-The Salesforce extensions add the `Invoke` and `Debug Invoke` CodeLens to a file that is in the correct format to send test events to a Function that is running locally. With one click, you can test a function that is running, by invoking it with a mock payload. You can also debug the function against the payload.
-
-A sample `payload.json` file that can invoke a function:

-
-### Stop Function
+See [run function start](https://developer.salesforce.com/docs/atlas.en-us.sfdx_cli_reference.meta/sfdx_cli_reference/cli_reference_run_commands_unified.htm#cli_reference_run_function_start_unified)
 
-Stop a function by running `SFDX: Stop Function`, which simply kills the local process.
