使用命令check_site，我得到了两条[TODO]，其中有“safety add”的建议，但我不太明白这两条消息的真正含义。我是否需要将Thumbs.db，.hugo_build.lock和/public/，/resources/添加到GitHub .gitignore文件中？

> blogdown::`check_site`()
... ...
| Checking for items you can safely ignore...
○ Found! You have safely ignored: .DS_Store
● [TODO] You can safely add to .gitignore: Thumbs.db, .hugo_build.lock
| Checking for items to ignore if you build the site on Netlify...
● [TODO] When Netlify builds your site, you can safely add to .gitignore: /public/, /resources/

目前，我的GitHub .gitignore文件内容如下所示：

.Rproj.user
.Rhistory
.RData
.Ruserdata
.Rdata
.httr-oauth
.DS_Store

那么我应该改为：

.Rproj.user
.Rhistory
.RData
.Ruserdata
.Rdata
.httr-oauth
.DS_Store

Thumbs.db
.hugo_build.lock

/public/
/resources/
