Hi Rodion,
Welcome to Guix!
Here is the fast way;
$ mkdir -p ${HOME}/tmp/packages/gnu/packages
$ export GUIX_PACKAGE_PATH="${HOME}/tmp/packages"
$ mv <package-file>.scm ${HOME}/tmp/packages/gnu/packages
$ guix build <package-name>
If you intend to contribute the package, keep reading.
> OK, that is not really a problem - I tried to create this package
> myself. So, I copied template "hello.scm" from documentation, modified
> it according to compton's build process.

> Question is - how I can test created package build process?
Here is what I do atm for developing packages.
$ guix environment guix --ad-hoc help2man git strace
$ eval `guix environment guix --ad-hoc --search-paths help2man git
strace`
$ unset GUIX_PACKAGE_PATH
$ export GUIX_BUILD_OPTIONS="--keep-failed --verbosity=3"
$ export BUILD_LOG=${HOME}/tmp/logs/pre-guix-build.log
$ mkdir -p $(dirname ${BUILD_LOG})
Inital setup
$ git clone --recurse git://git.savannah.gnu.org/guix.git
Update
$ git pull --recurse-submodules
Build
$ ./bootstrap
$ ./configure --localstate=/var
$ make
$ make check
Runs in the foreground
optional unless editing damon code
$ sudo ./pre-inst-env guix-daemon --build-users-group=guixbuild
Edit/add code under gnu/packages directory.
$ export GUIX_BUILD_OPTIONS="--keep-failed --verbosity=3"
$ ./pre-inst-env guix build hello &>/dev/stdout &>${BUILD_LOG}
$ ./pre-inst-env guix lint hello
