Narrative:

After taking off at ZZZ as the pilot monitoring I called positive rate and the pilot flying called gear up and speed mode. I preceded to put the gear up after 10-15 seconds we got a triple chime associated with two warning messages 1. Nose door 2. Gear disagree. Looking at the gear indications we noticed the nose gear was the problem. The captain called for the QRH and told me to [advise ATC] and that we had to return to ZZZ. I contacted ZZZ tower at the time and explained to them the situation and that we wanted to return to the airport with vectors while we run some checklists. We ran the QRH remaining under 200 KIAS turned the recommended hydraulic pumps to 'on' and pulled the manual gear extension and put the gear handle down after that we noticed all three were green and down. We proceeded to run the in range configuration and approach checklists. After completing that we were vectored on the ILS where we made a safe landing and exited and proceeded to gate.
