In one sentence, describe what the following article is about:

Just as with outdoor soccer, you will need a pair of shin guards, long socks, and shoes. However, instead of outdoor soccer cleats, you will need a pair of indoor soccer shoes, which differ by having flat outsoles. Lightweight sneakers or running shoes can also work in a pinch, but you will not have the same speed and ease of movement. If you are an outdoor soccer player adapting to playing indoors, spend some time getting used to juggling the ball indoors. Whether you are playing on astroturf or a hard, smooth surface, the ball will have far less traction and you will likely have to move your feet more quickly to control the ball across the field. Indoor soccer is faster-paced than outdoor soccer, which will keep you in shape and also sharpen your playing skills but the rapid pace will take some getting used to.  Focus on making quick passes and small, controlled movements with your feet until playing faster comes naturally. Be more verbally communicative. Because the game is so fast and you are in an enclosed space, expect to talk to your teammates more. Oftentimes you may deliver a pass only to find yourself in a great spot to receive the ball again. In these moments, it’s best to yell “pass” or otherwise let your teammates know where you are positioned.

Summary:
Get the right gear. Practice playing with the ball indoors. Play fast.
