I suggest adding a separate documentation directory.

I agree to add it as a separate page, but I recommend a subpage under Quick Start, such as the Version Upgrade Guide.

@delei Thanks for the suggestion!

Quick Start is for new users, while a Migration Guide targets existing users upgrading from an older version. These are different audiences, so nesting migration content inside Quick Start could confuse readers.

For example:
• Vue Migration Guide (top-level): https://v2.vuejs.org/v2/guide/migration
• JUnit 4 → 5 Migration (top-level): https://docs.junit.org/current/user-guide/#migrating-from-junit4

Keeping Migration Guide as a sibling of Quick Start ensures:
1. Clear separation between onboarding and upgrade content
2. Easier discoverability for migrating users
3. Cleaner, more focused Quick Start section

I recommend placing Migration Guide at the top level rather than inside Quick Start.
