 # linkwallet
 
+[![Go Report Card](https://goreportcard.com/badge/github.com/tardisx/linkwallet)](https://goreportcard.com/report/github.com/tardisx/linkwallet)
+
 A self-hosted bookmark database with full-text page content search.
 
+Searching uses English stemming, providing matches against similar words, in both page
+titles and page content. Searches are lightning fast.
+
+![Search][screenshot_search]
+
+Bookmark content is automatically re-scraped periodically. Tags can be applied (though with 
+the full-text search they are often not needed). Bookmarks can be easily managed, and can be
+imported or exported in bulk.
+
+![Admin][screenshot_admin]
+
+Bookmarks can be added with two clicks via the bookmarklet.
