Crowdin.com-Markdown Integration

I have a project ([login to view URL]), which contains a lot of bash and python source code (which is using gettext syntax to make localization easy), and some documentation written in markdown, all of which can be found in various GIT repositories. I would like someone who can help me setup a script which I can run on my Ubuntu server, which will move the relevant content back and forth between [login to view URL] and the various repositories. It would be ok to have a separate script for exporting from repository to Crowdin, another for importing from Crowdin, and I have no problem running it and giving it parameters such as git repository address and Crowdin information at time of execution. I expect that this will be straightforward for the gettext stuff, but I am not sure what is involved in extracting and later re-inserting content into markdown files. I would like (1), and estimate on how much to create the script(s) to automate transfering back and forth from Crowdin to my repositories; and (2), an estimate on how much it would be to do the same for markdown files in my repositories. I welcome questions, comments, and suggestions of things I should consider.
