Repotting after rejuvenation

[Goldie101]

We have an orchid that was in terrible shape, so for the past several weeks I have been soaking and drying the roots each night. It appears to actually be working as there are new root buds and new leaves forming.

My question is this. How do I know when to put it back into soil (or should I do hydroponic) and any guidance on exactly how to do that. This is the first orchid we've had and it went badly at first, but we may have recovered it, but I don't want to screw it up at the final turn. Thanks.
