Please Help need to put langstroth nuc into top bar hive

[dogpatch]

I am new to beekeeping and suffered the devastating loss of my first bees...I have modified my hive and now am confident that the next bees will be safe with me.  I have been able to find someone with a nuc and I am picking up this week.  However I have a top bar hive and the nuc is a langstroth nuc.  Can anyone perhaps give me guidance on how to transition the bees into the new hive.
I appreciate any help that you can give
Thanks

They have an adapter for migrating nucs into topbar hives.
