Flask is quite the most popular Web framework nowadays, so finding online reading material for it is not that hard. For instance, a quick search on Google will surely give you one or two good articles on most subjects you might be interested in. Nonetheless, subjects such as deployment, even though much discussed on the Internet, yet raise doubt in our fellow web warriors' hearts. For that reason, we have stashed a nice step-by-step "deploy your Flask app like a boss" recipe in our last chapter. Along with it, we'll advise you on a few very special places where knowledge is just there, thick and juicy, lying around waiting for you to pinch wisdom. With this chapter, you'll be capable of delivering your products from code to server, and maybe, just maybe, fetching some well-deserved high fives! Welcome to this chapter, where code meets the server and you meet the world!
