## Changing How Many Blog Posts Show on Sidebar
By default, 5 recent blog posts are shown on the sidebar.
You can configure a specifc amount of blog posts to show by adding a `blogSidebarCount` setting to your `siteConfig.js`.
The available options are an integer repreenting the number of posts you wish to show or a string with the value 'ALL'.
Example:
```
blogSidebarCount: 'ALL'
```
