After the introduction of git version control idea, the file will change color:
Red-brown: After creating not add, did not submit, version control is not within the range, this time the file is reddish-brown, you need to add file;
Green: After you add a file green, did not submit (commit);
Blue: the original has a file, not submitted after the changes (commit) is blue, then submit, become normal color.
git use a little bit of experience:
1, prior to commit review and see whether there is an error checking code, whether the norms;
2, usually develop test development branch, do not go to the local master branch development;
