+# sxbm-dmenu
+
+This is a small example dmenu wrapper around sxbm. Feel free to customize/tweak
+it to your needs.
+
+By default `sxbm_dmenu` takes the exact same arguments as `sxbm ls`. Invoking
+`sxbm_dmenu` without any argument will list out all the bookmarks in your
+`$prompt` (dmenu by default) and will open that link via `sxbm open`.
+
+To list matching titles: `sxbm_dmenu title`
+To list matching tags: `sxbm_dmenu +tag`
+
+* Additional arguments: `sxbm_dmenu` takes two additional arguments.
+
+    * `-y` or `--yank` will copy the selected link to your clipboard
+      (requires `xclip`) instead of opening them. Example: `sxbm_dmenu -y title`
+
+    * `-a` or `--add` is an alias to `sxbm add`.
+      Example: `sxbm_dmenu -a link.com +tag`
+
