 # Finder: CLI searcher and browser REPL
 
+## About
+
+Finder is a terminal-based searcher.
+
+It's like [ranger][], but with a search-like interface.
+
+It aims to replace the fatigue of frequently using [find][] + [grep][]
+combinations for finding files, but it's also intended for searching and
+browser other contents such as file lists, spreadsheets and remote queries.
