 # 💡 Tips
 
-- Most of the commands accept optional arguments (eg, `glo develop`, `glo f738479..188a849b -- main.go`, `gco master`).
-- `gd` supports specifying revision(eg, `gd HEAD~`, `gd v1.0 README.md`).
-- Call `gi` with arguments to get the wanted `.gitignore` contents directly(eg, `gi cmake c++`).
