== Setup of a New Application Program Project

[start=1]
. The easiest way of creating a _new_ software application project is to copy an _existing_ one. This will keep all
file dependencies. For example you can copy `sw/example/blink_led` to `sw/example/flux_capacitor`.
. If you want to place you application somewhere outside `sw/example` you need to adapt the application's makefile.
In the makefile you will find a variable that keeps the relative or absolute path to the NEORV32 repository home
folder. Just modify this variable according to your new project's home location:

[source,makefile]
----
# Relative or absolute path to the NEORV32 home folder (use default if not set by user)
NEORV32_HOME ?= ../../..
----

[start=3]
. If your project contains additional source files outside of the project folder, you can add them to
the `APP_SRC` variable:

[source,makefile]
----
# User's application sources (add additional files here)
APP_SRC = $(wildcard *.c) ../somewhere/some_file.c
----

[start=4]
. You also can add a folder containing your application's include files to the
`APP_INC` variable (do not forget the `-I` prefix):

[source,makefile]
----
# User's application include folders (don't forget the '-I' before each entry)
APP_INC = -I . -I ../somewhere/include_stuff_folder
----
