There is a lot you can do with the Twilio Serverless Toolkit. Here are some common examples of commands you might want to run.

There are two ways you can use the [toolkit](/docs/labs/serverless-toolkit). If you are already using the Twilio CLI, you can install it via a plugin. Alternatively, you can use the toolkit as a standalone using twilio-run via npm or another Node.js package manager.

Throughout the docs we'll reference the Twilio CLI commands.

## The list command

The list command allows you to list out:

* Your *services* that are associated with your account
* The *environments* for a specific service
* Available *builds* in a specific service
* As well as the *functions*, *assets* and *variables* currently deployed in a specific environment of a service

Here is some common tasks you might want to do with the list command.

```bash title="List existing Serverless services"
# List all existing Serverless services in a formatted way:

twilio serverless:list services

# Only list the service SIDs and unique names in a table:

twilio serverless:list services --properties sid,unique_name
```

```bash title="Promote a deployment from one environment to another"
# Activates the same deployment that is on the "dev" environment to the "stage"

twilio serverless:promote \
  --source-environment=dev \
  --environment=stage
```
