+## Detection Logic
+
+The plugin tries to detect and configure `fzf` from a variety of environments. It tries these in order:
+1. Using `fzf --zsh` if `fzf` is a recent version (`>= 0.48.0`)
+2. OpenBSD default paths
+3. Debian-based distributions
+4. OpenSUSE
+5. Fedora
+6. Cygwin
+7. MacPorts
+8. Manual fallback search paths:
+    - `~/.fzf`
+    - `~/.nix-profile/share/fzf`
+    - `$XDG_DATA_HOME/fzf` (or `~/.local/share/fzf`)
+    - `/usr/share/fzf`, `/usr/local/share/examples/fzf`, etc
+    - Results of `fzf-share` or `brew --prefix fzf`
+If none of these are successful, the plugin shows an error prompting you to set `FZF_BASE`.
