If you will be installing Movable Type into your cgi-bin directory, note that you will need to upload your static files--images, docs, and styles.css--into a directory outside of the cgi-bin. Static files cannot be left inside the cgi-bin, because the web server will try to execute them, rendering them unusable through the web interface.
A solution is to create a new directory in your web-accessible area called mt-static, then upload images, docs, styles.css, and mt.js into that directory. Note the URL corresponding to mt-static, because you will need to use it later when configuring the system in your mt.cfg file.
So while it isn't mentioned in the first paragraph, it is mentioned in the second. Kind of a half-bug.
