<!--- Provide a general summary of your changes in the Title above -->
This is a documentation about the installation of git lifs in the current project and how it can be used. I have referred to the git tutorials for the different platforms on ehich git lfs can be installed and can be used to refer the large images in a different server without they been present in the code repo.
## Description
<!--- Describe your changes in detail -->
All the diff platforms Mac, Windiws, Linux, Rhel/CentOS, Debian are mentioned.
The image files which are referred are present in the .gitattributes file as below:
_prediction/src/algorithms/identify/assets/ filter=lfs diff=lfs merge=lfs -text
