The second open enrollment period for Americans to sign up for health insurance under the Affordable Care Act begins Saturday, when people across the country will start visiting in hopes of finding the best health care option for their families. Better known as Obamacare or the ACA, President Barack Obama’s signature domestic policy achievement has resulted in more than 8 million new insured people since it launched last year. This open enrollment round presents a second chance for the uninsured to purchase insurance via the program, and for insured people to reenroll in or change their existing coverage.

Mountains of rumors and misinformation have clouded the air around the health insurance marketplace, which, despite all the negative hype, often offers more affordable insurance plans than those of many private companies by taking advantage of the synergistic effect of its subsidies, pooling, competitive nature and other provisions.

In reality, however, the process for enrolling in health care via is a straightforward one, though it does require a small investment of time and some basic knowledge. Here's how to apply:
