[Koha] Koha enquiry for a new library

Hi All, Our library doesn’t have a library system yet. We are new branch campus in Qatar and we are investigating about various possibilities for managing our physical collection which includes Koha. Even though I heard a lot of positive feedback about Koha in general, I would like to hear from you the personal experience of setting up and using Koha. 1. Does your library had any other library system before implementing Koha? If not, how easy/complicated to use this for a new library? 2. What things should I be considered before start using Koha? Any other recommendation/suggestions are welcome! Thanks & Regards, *Sumayya Ansar*
