What is inbound marketing?

Hi everyone, i'm a fresh-man of HubSpot Community. I'm just thinking about "inbound marketing" meaning. How to clear the meaning out of the book?

Inbound marketing is simply just marketing that uses content and experiences for their users as a way to attract customers. It's more focused on building relationships instead of trying to get as many people as possible to see an ad.
