How does my plugin appear under the WYSIWYG Editor in "Create new article"-Screen

I have written a Wordpress Plugin and now I want, that the Plugin appears (HTML Form) in the "开发者_如何学运维Create New Article"-Screen unter the WYSIWYG Editor (after installation and activation). How can this be done. In the Codex and other sources I haven't found anything related to that problem.

BR & Thanks in advance, mybecks
