Adding modules (or widgets) to your website is what connects your customers to IOdesk. For an explanation on how to install this module after creating it, see module installation.
In IOdesk, navigate to
Modules -> Create and manage. Click on the
Create new module button
This will bring up a selection of available modules, click on
Get started for the chat module you want, e.g. Support module with live chat.
This will start a guide that will take you through the creation of the chat module step-by-step. So that you can configure it to look and behave just the way you want.
Also remember to set your business hours, as these will have an impact on the chat module (if you are online to answer questions or not)
