## Clone with submodule recurse
add *--recurse-submodules* to clone command
## Add in staging only a part of modification done in a file
`git add -p`
this will ask if you want to add each modification with this option:
- *y* - Yes, add this hunk
- *n* - No, dont add this hunk
- *d* - No, dont add this hunk and all other remaining hunks. Useful if youve already added what you want to, and want to skip over the rest
- *s* - Split the hunk into smaller hunks. This only works if theres unchanged lines between the changes in the displayed hunk, so this wouldnt have any effect in the example above
- *e* - Manually edit the hunk. This is probably the most powerful option. As promised, it will open the hunk in a text editor and you can edit it to your hearts content
## delete a file only from git repository

## delete a file from complete history
