What does it mean to back a project (pledge)?

When you back a project, you’re pre-ordering the product. That means you'll get it once it's produced. Besides getting the product itself, you're also joining a community. Follow along the production process, take part in important surveys and give the creator valuable feedback.

What is Kickstarter?

Kickstarter is a launchpad for creators to raise funds for the initial production of their invention. Backers (that's you!) can support the creator by pre-ordering the product at a discounted price.

How do I pledge?
