From Tutorials template

Let's start migrating content from Tutorials Template:

Note that Tutorials template was renamed to Onboarding due usage on Onboarding pages, If you didn't agree that, fill an issue.

Changes:

frontmatter:

• stepNumber frontmatter variable is a number that you can provide to order your markdown files in steps.
• time frontmatter was removed because this time to read is calculated internally, however, the time to read component wasn't completed yet.
• buttonTitle was removed because is unused in most of the projects.
