bash <(curl -s https://raw.githubusercontent.com/ammopt/koha-ill-dev/master/start-ill-dev.sh)
2) Checkout to branch b_36243
cd /kohadevbox/koha/Koha/Illbackends/FreeForm
git checkout b_36243
3) Enable CirculateILL sys pref
4) Create a new ILL request, visit:
<staff_url>/cgi-bin/koha/ill/ill-requests.pl?method=create&backend=FreeForm
5) Set "type" = Book and enter '42' on the cardnumber input, click "Create"
6) On the top toolbar, click "Confirm" and confirm the following screen.
7) You now have a new option "Check out" on the toolbar. Click on it. Notice it explodes.
