Hey guitar tricks !!

im ready to start recording my own songs and putting pieces together . I only have an acoustic guitar and a PSR-E473 keyboard but have some money to invest into recording equipment /programs .

my main goal is to record what I play an add other stuff like piano or other instruments to the piece . Since learning the fundamentals an almost all triads/inversions an a bit of accounts course level 1 I’ve been inspired to want to go further with this .

im guessing I would need a microphone and a program similar to add all this stuff . I have used GarageBand but not a big fan . 
I have a good laptop as well. 

What would your go to or recommendations be for a good microphone/ programs to add music on. 

Thankyou guitar tricks.
