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

Most universities require you to submit some basic details using an online application. These details may include things like your name, address, schools attended, etc. Complete this part of your application before you do anything else. Some schools also require letters of recommendation to be submitted via an online system. You may need to submit your recommenders email addresses so that they can access this system. Your applications will also likely include some paper items, such as your statement of purpose, official transcripts, writing samples, or other required materials. Collect these items and seal them in a large envelope. Make sure that you give yourself plenty of time to send your packets so that they will arrive before the deadline.  Address the packets. Make sure that you double check the addresses for each of your packets to ensure that they will be delivered to the correct location. Pay for postage. International postage can be quite expensive, so make sure that you reserve some money to pay for this cost. Pay the postage for each of your packets and send them out. Waiting to hear back from schools may be the most difficult part of the process. It can take weeks or even months for PhD application committees to make their selections. Many schools alert applicants of an acceptance or rejection via email as well as with a paper letter, so keep an eye on both of your inboxes.

Summary:
Complete online application components. Prepare your application items to mail. Wait for responses.
