Run Git Pull with Submodule before install

[GRomR1]

Hi all

I don't find information about pulling from repo. Then I want to share you an advice to do next.

Don't forget to run a specific git pull command to get all strategies from external repo's.

git submodule update --init --recursive

for the first time. All submodules will be pulled down locally.

To update submodules, we can use

git submodule update --recursive --remote
