There is a file in your git root directory named .gitignore. It's a file, not a command. You just need to insert the names of the files that you want to ignore, and they will automatically be ignored. For example, if you wanted to ignore all emacs autosave files, which end in ~, then you could add this line:

*~

If you want to remove the unwanted files from your branch, you can use git add -A, which "removes files that are no longer in the working tree".

Note: What I called the "git root directory" is simply the directory in which you used git init for the first time. It is also where you can find the .git directory.

So based on what you said  these files are libraries documentation you don t want to delete but also don t want to push to github  Let say you have your project in folder your project and a doc directory  your project doc    Remove it from the project directory  without actually deleting it   git rm --cached doc    If you don t already have a  gitignore  you can make one right inside of your project folder  project  gitignore   Put doc   in the  gitignore  Stage the file to commit  git add project  gitignore Commit  git commit -m  message    Push your change to github

git ignore is a convention in git  Setting a file by the name of  gitignore will ignore the files in that directory and deeper directories that match the patterns that the file contains  The most common use is just to have one file like this at the top level  But you can add others deeper in your directory structure to ignore even more patterns or stop ignoring them for that directory and subsequently deeper ones    Likewise  you can  unignore  certain files in a deeper structure or a specific subset  ie  you ignore   log but want to still track important log  by specifying patterns beginning with    eg     log  important log   will ignore all log files but will track files named important log  If you are tracking files you meant to ignore  delete them  add the pattern to you  gitignore file and add all the changes    delete files that should be ignored  or untrack them with    git rm --cached  lt file list or pattern gt     stage all the changes git commit git add -A    from now on your repository will not have them tracked   If you would like to clean up your history  you can    if you want to correct the last 10 commits git rebase -i --preserve-merges HEAD 10    then mark each commit with e or edit  Save the plan  Now git will replay your history stopping at each commit you marked with e  Here you delete the files you don t want  git add -A and then git rebase --continue until you are done  Your history will be clean  Make sure you tell you coworkers as you will have to force push and they will have to rebase what they didn t push yet
