Making GIMP document
This isn’t really helpful. If you want to ask a question, it helps to write down what your issue is.
Welcome to the GIMP discourse, @Aaradhya_Singh !
We usually talk about GIMP making images rather than documents - to get started, you have to download the GIMP installer from gimp.org (or from your package anager on Linux computers) and then there is help available from within the program on yuor desktop computer.
