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

Deviant Art is a social network site for artists to post and promote their artwork. Many emerging artists start on Deviant Art. To sign up for a username, provide an e-mail address and start posting. You can post individual panels from your manga, art of the characters, or publish the manga in its entirety.  Interact with people on the site. Talk to people to get your name out there. Browse other people's art. Leave comments and feedback. The goal is to network so people will come to browse your art.  Choose a username that is memorable. Your username should also be something you want connected with you art when you get ready to publish it. Artists and people interested in graphics look up tutorials. Post a tutorial about something you are skilled at. This can be drawing animals, shading, or using a drawing program. Many people don't know how to go from doing one-shot art pieces to full manga. Make a tutorial that explains how you developed your manga.  Tutorials help build your reputation as knowledgeable and helpful. This is a good way to get your name out, but also get people to look up to you. These tutorials can be posted on Deviant Art, or other social media sites like Tumblr. A website gives people a place to go to check out your art and your biography. You can also link to your manga from your website when you get ready to publish it. You may want to post pages of your manga for free to entice readers to buy it. Or, if you have more than one manga, post one for free on your website and then sell another one.  You can pay for domain space or try free sites. Domain space requires a yearly or monthly fee; free sites have ads. Take that into consideration before building one. Instead of a website, try creating a Tumblr. On Tumblr, people can reblog your work so that you get a wider audience. You can also create links to your social media accounts. Tumblr could be a good way for you to interact with people, take prompts, and build a following. Before you start charging for your work, post free web comics. Web comics help get people interested in your art. They also showcase your talent. This helps people want to see more of your art. The goal is to introduce people to your art, make your name known, and have them like your art enough to buy it one day. For manga, you may want to publish panels or pages as a serial. Release a new page or panel once a week. That way you can practice your manga skills and promote yourself as a manga artist.  You can post the web comics on Deviant Art, Drunk Duck, or Smack Jeeves. These three sites are geared towards hosting web comics. Post the web comic everywhere else, too. Put it on Tumblr, Facebook, Twitter, Pintrest, or any other social media site. You want to get your art seen by as many people as possible. The web comics can be short one shots. They also can be installments of an ongoing manga. Consider drawing fanart of popular media, like movies and television shows. Once people know who you are, offer to draw commissions. Charge a small fee in exchange for drawing prompts that people would like to see.  Commissions allow you a chance to make a small profit for your art work. It can also help you gauge interest in your work. Charge different prices for different levels of difficulty. Full color art with multiple characters will cost more than a black and white sketch. You are trying to get your name noticed, but this doesn't mean posting art constantly. Focus on the quality of the art you post. Spend time on it, polish it off, and perfect it before posting. Posting your best work shows your followers that your work is always worth looking at.

Summary:
Get a Deviant Art account. Make tutorials. Build a website. Post web comics for free. Open up commissions. Think about quality over quantity.
