In order to create your personal homepage, you first have to log in to the ID Portal (Identity Management Portal) using the credentials of your LRZ account (username and password).
In the category "Self Services", click "create/edit personal homepage", then choose your id. You may then choose a name (and, optionally, aliases) for your homepage.
After you have created your homepage, you will want to access your homepage and publish your content. There are various ways for you to accomplish this.
