To add and edit static blocks, log in to the admin panel of your store and go to CMS menu>Static Blocks. On the page that opens you'll see a list with the current blocks. To edit a block just click on its name. To add a new block click on the Add New Block button in the upper right corner of the page.
On the following page type a name and an identifier for the block in the respective fields. The identifier shouldn't have spaces in its name. You can use the Status drop-down menu to enable/disable the block. Then use the editor to specify the content of the block. You can put anything from text to media files. After you're done save the block and now you can use it.
