If you already have your own website hosting your text, essays, and writings and you'd like to put others on notice that they can use and share your text, start by choosing a license for your work.
Choose a license for your images
On the "Mark your content" page of the license process, copy the code provided by highlighting it with your mouse and hitting ctrl-c (command-c on a Mac).
The specifics of the last step will depend on how you edit your website. Most desktop website tools like Dreamweaver, Frontpage, or GoLive offer a "code view" that lets you see the code that makes up your page. Near the end of the page you are hosting text, before you see </body></html>, paste in the code copied in the previous step by clicking the page and hitting ctrl-v (command-v on a Mac).
