在git開發(fā)中鞋屈，難免會因為分支過多難以管理昭抒。所以注釋是有必要的；
在安裝之前先要安裝npm；
sudo apt install npm

npm -v? 查看版本徙瓶，可以看到npm已經安裝完畢；
注意！Ｏ劭谩Ｂ冈獭：如果出現：說明你沒有切換到root用戶權限应闯；
最后執(zhí)行npm i -g git-br
安裝git分支注釋成功态贤；
正巢绺撸可以這樣添加注釋：
git config branch.分支名.description '這里添加注釋'
然后獲取分支注釋谬以；
git config branch.分支名.description
現在添加注釋不變邑雅，但是可以? git br 命令獲取分支和注釋；
友情提示：
在安裝之后可能會出現沒有tab自動補全了洞难，這個問題沒有細去研究揭朝，過一會自動好了编丘；
不過可以這么做：
1.下載配置文件?git clone git://git.kernel.org/pub/scm/git/git.git
2.cp? git/contrib/completion/git-completion.bash? ~/.git-completion.bash
3.在.bashrc中添加??source ~/.git-completion.bash
4.source?~/.bashrc
這樣可以解決沒有自動補全的問題；
