If you have ever installed this theme gem, you can use the command `bundle info --path jekyll-theme-chirpy` to locate these files.

-
-@import {{ site.theme }}
-
-// add your style below
-```
-
-### Changing the Number of Tabs
-
-When adding or deleting files in the `_tabs` folder, you need to complete the section [Customing Stylesheet](#customing-stylesheet) first, and then add a new line before `@import`:
-
-```scss
-$tab-count: {{ site.tabs | size | plus: 1 }};
-```
-
-### Publishing to GitHub Pages
-
-See the [deployment instructions](https://github.com/cotes2020/jekyll-theme-chirpy#deployment) of `jekyll-theme-chirpy`.
-
-### Updating
-
-Please note that files and directories in this project may change as the [`jekyll-theme-chirpy`][chirpy] is updated. When updating, please ensure that the file directory structure of your Jekyll site is the same as that of this project.
-
-And then execute:
-
-```console
-$ bundle update jekyll-theme-chirpy
