New Non Green fingered Orchid owner

[Jaqs]

First and foremost apologies for the long message ahead.

Hi there I am new to the orchid scene and the forum, well I say new I have had my orchid since November 2021 it was purchased for me for my birthday by my brother, the flowers lasted soooo long then they dropped off and I kept the orchid to see if it would re flower.
I used to have it in the far end of my living room and it did nothing, so quite a few months ago I moved it to a windowsill and I have just looked at it and its gone wild.
I have tried reading up on what I should do with it but all the information is very confusing.
It looks like it could be due to flower at some point in the near future as there has new buds appeared along with more branch offs.
So I am looking for advice on what I need to do i.e. repotting and how, making new plants from this one or what useful information anyone with any knowledge can give me really.

I can take and post pictures of my orchid to see what i am facing

Thank You in advance
Jaqs
