+# iwd-dmenu
+An interactive iwd menu using dmenu.
+
+
+
+Used with my [dotfiles](https://www.git.mcarlson.xyz/dots/). This script has some hacky solutions, will maybe improve them ¯\\\_(ツ)_/¯
+
+Aside from grep word boundaries, this script should be pretty portable.
+
+Some dependencies:
+- iwd (duh)
+- dmenu (with center and password patches)
+- [herbe](https://github.com/dudik/herbe)
+
+# Installation
+```shell
+$ git clone https://github.com/mslcarlson/iwd-dmenu/
+$ cd iwd-dmenu
+$ sudo make install
+```
+
+# Usage
+Just run `iwd-dmenu` from the command line.
