@hamzaibrahim21 thanks for adding the content:

• for the new seminar, can you please use the content from LSF ('Bemerkungen' section).
• the seminar is new (not the same as the CADD seminar we offer in SS, can you add a new section for it please
• can you please order the course offers so that the newest one are listed on top, at present the WiSe23/24 ones, and add some tag 'previous' to the old ones.
• we can add the GH links later as you suggested

@AndreaVolkamer Thanks for the feedback. I added the paragraph , reordered offered courses and added previous tag. If there is anything still missing, please let me know.
