Example:
A project residing in /var/www/dalu/project
with a binary project at /var/www/dalu/project/project
and a systemd service named dalu-project.service
with the binary being owned by dalu:dalu

gomanager add \
--root-path="/var/www/dalu/project" \
--binary-path="project" \
--service-name="dalu-project.service" \
--user="dalu" \
--group="dalu"

let's assume we'd like to resulting binary to be moved to /usr/local/bin/project after building
we add
--binary-target-path="/usr/local/bin/project"

or with short notation:
gomanager add \
-r="/var/www/dalu/project" \
-b="project" \
-s="dalu-project.service" \
-u="dalu" \
-g="dalu"

with moving the compiled binary
-t="/usr/local/bin/project"
