You can go to https://imgflip.com/memegenerator and make a meme there. It's very easy and self explanatory. Just upload an image and add text. You can be as creative as you want. If you're not as creative, then you can go to Google and find quotes, jokes and cliches and use that text. You can also create gifs and other caption forms...but for the sake of this tutorial, we are focusing on image memes.
