It seems to me that "predis" is a submodule . Therefore, your main repo does not directly track this submodule.
What you are actually βaddingβ is a pointer to fixing this submodule. Now, if you want to actually commit / click the contents of this submodule, you will have to go to this directory
$cd predis
$git status
$git add [whatever you want to add]
$git commit -m "your message"
$git push
,
$cd ..
$git add predis
$git commit
$git push
$git status
( ).
