What is a one-sentence summary of the following article?
Most people don't know what cheerleading really is. If your parents think that cheerleaders are mean people that do nothing but wave pom-poms, explain to them what you really want to do, how much you love cheerleading, and that all-star cheerleading is not the same thing as cheering for your school or football. Make sure you aren't putting them on the spot. Make sure they agree with you and you aren't pressuring them. They will more likely help you if you stay calm and show them your mature. Be happy, smile, make friends, don't be mean, laugh a lot, and be sporty! Remember that being mean and rude to other teammates could get you kicked off the cheerleading team, so remember to be nice to everyone in your team and outside our team. Also make sure that you pick a good team. Before you become an all-star cheerleader, you need to know what all-star cheerleading is. Look up videos on Youtube or visit the USASF (US All-Star Federation) website to see how it's like being an all-star cheerleader. Know all the rules and levels so you'll have an idea what level you'll be on and what you'll be doing. And be sure to know the difference between all-star cheerleading and football/basketball cheerleading before you sign up! If you're tall and strong, you'll probably be a base or backspot. If you're short, flexible, and agile you'll probably be a flyer. If you're a combination of both, maybe you could be two things at a time! Look on the website for pictures, look on youtube for videos, and see if on the website they have requirements for the team you want to try out for. For previews on competitions go to websites like Jamfest or U.S. Nationals. Remember to find a good team. If the team only has seven girls or goes in only two competitions a year, you might not want to join if cheerleading is your passion. Make sure you join a good sized teams with plenty of levels and that goes on competitions! And if possible, try joining a team that goes to Worlds.

Summary:
Get your parents permission and support. Start acting like a cheerleader, even before you make the team. Research good cheerleading. Decide what you're going to be. Research an all star team in your area so you have all the information.
