Summary by cubic

Reorganized docs to move “Features” into a new “IDE Extensions” section, centralizing install and quick start there and removing the old overview. Updated links, navigation, and images, and added redirects to keep existing URLs working.

• Refactors

  • Renamed “Features” to “IDE Extensions” in the docs nav and added install and quick start.
  • Moved Agent, Chat, Edit, Autocomplete, and Plan pages to /ide-extensions/*.
  • Removed getting-started/overview and folded its content into the IDE Extensions quick start.
  • Updated links across README, home, index, guides, customization, and reference pages.
  • Added quick start GIFs and fixed image paths.
  • Updated IntelliJ/VSCode tutorial files to point to https://docs.continue.dev.

• Migration

  • No breaking changes; all /features/* and /getting-started/* URLs redirect to /ide-extensions/*.
  • Update any hard-coded external links if needed to the new /ide-extensions/* paths.

<file name="docs/chat/how-to-use-it.mdx">

<violation number="1" location="docs/chat/how-to-use-it.mdx:28">
The link uses the slug `#how-to-use-%40-for-additional-context`, but the target heading generates `#how-to-use--for-additional-context`, so this anchor will be broken. Please update the slug to match the generated ID.</violation>
</file>

<file name="docs/docs.json">

<violation number="1" location="docs/docs.json:460">
/how-to-use-continue should point to the new quick start page instead of the homepage to preserve the expected content for that legacy URL.</violation>

<violation number="2" location="docs/docs.json:460">
/quickstart should redirect to the relocated quick start doc instead of the homepage so existing links continue to land on the right content.</violation>
