While there are multiple factors to be considered when launching an in-app Guide like launching it at the right time, at the right place and when the user needs it and making it more contextual based on the analytics, a quick addition which makes a motivating for the users to start/ navigate through a guide is knowing right off the bat- "how long is this guide/ tour!"
In a multi-step Guide, "add steps in the title"
(or place it whever you like) in each modal to make it obvious and motivating for the users to navigate through your guides until completion. Knowing how many steps are involved and being able to the progress made/ how much is left is always more exciting and motivating.
