A few hints for writing the "Essay"

This is not a literary essay, but more of a technical/process oriented one. You should strive to write clearly and without many grammatical and spelling errors. Aim for a neutral and objective tone, as that will serve as useful preparation for the writing you will be doing for your master thesis. Try to focus on the main issues, rather than just a plodding "walk in the woods" (first I did this, then I did that, then some more of this.....). Emphasis should be on main challenges and solutions.
