Migration from VuePress
Config
Section titled “Config”Sidebar
Section titled “Sidebar”The sidebar is no longer automatically populated from frontmatter. You can read the frontmatter yourself to dynamically populate the sidebar. Additional utilities for this may be provided in the future.
Markdown
Section titled “Markdown”Images
Section titled “Images”Unlike VuePress, VitePress handles base of your config automatically when you use static image.
Hence, now you can render images without img tag.
- <img :src="$withBase('/foo.png')" alt="foo">
+ Use <img.*withBase\('(.*)'\).*alt="([^"]*)".*> regex to find and replace it with  to replace all the images with  syntax.
