+
+## Getting Started
+
+In order to use the segmentcli to work with your workspace you must have the 
+Analytics Live Plugins featured enabled in your workspace and you must 
+authenticate with that workspace.
+
+### Enabling the Analytics Live Plugins feature
+
+Reach out to your Customer Support Engineer (CSE) or Customer Success Manager (CSM) 
+to have them add this feature to your account.
+
+The command to authenticate is as follows:
+
+```bash
+$ segmentcli auth <ProfileName> <AuthToken>
+```
+
+`ProfileName` - is the name you give to this workspace so you can distinguish
+between various local profiles.
+
+`AuthToken` - is the AuthToken associated with your workspace. You must create
+an Auth token in your Segment workspace.
+
+### Creating an Auth Token
+
+1. Log into https://app.segment.com
+1. Navigate to Settings > Workspace Settings > Access Management > Tokens
+1. Generate a new token using the "Create token" button with the Workspace Owner role.
+
+## Uploading Your Analytics Live Plugins to Your Workspace
+
+In order to upload your Analytics Live Plugins you'll need the following command:
+
+```bash
+$ segmentcli upload <SourceId> <FileName>
+```
+
+`SourceId` - This is listed next your Write Key in the Segment app.
+`FileName` - The name of the JavaScript file containing your code.
+
+Note: It will take a few minutes for your Source's setting payload to be update
+with the Analytics Live Plugin file URL.
+
+### Finding Your SourceID
+
+1. Log into https://app.segment.com
+1. Navigate to Connections > Sources
+1. Choose the source for which we're adding Analytics Live Plugins
+1. Navigate to Settings > API Keys
+1. You'll find the "Source ID" at the top of the page.
