Where to write code?

[ReneKat]

Hello WSL community,
I am am new to WSL and found this setup guide extremely helpful.
My questions is where should I be writing my code? I thought I could write my code in Windows editor and run this code in Ubuntu, but when I have tried that linux complains about /r in my code.
.../ncbi-blast.sh: line 8: syntax error near unexpected token $'do\r''`

In your setup guide you install VCode; however, I am accustomed to using Atom. So, I wrote my code in Atom on windows.
Any and all help would be appreciated.
Thank you!

Solved this by changing the line sequence in Atom from CRLF to LF
