-# FocusVolumeControlPlugin
+# Focus Volume Control Plugin
 
+A plugin for the Stream Deck+ to control the volume of the focused application.
+
+## Description
+
+This Stream Deck plugin utilizes the Stream Deck+ encoders and screen to allow you to control the volume of the focused application.
+Application volume is changed with the windows volume mixer.
+
+Unlike faders or potentiometers, the encoders of the Stream Deck+ spin infinitely in either direction. Which means when you change your focused application, you don't have to worry about desynchronization with the current app.
+The screen updates to show the name/icon of the app so that you can always know what you're about to change.
+
+![Focus volume control plugin preview](previews/preview.png?raw=true)
+
+## Developing
+
+build the solution with visual studio
+run `install.bat <debug | release>`
+
+to debug, attach to the FocusVolumeControl running process
+
+
+There is also a secondary sound browser project which can be used for viewing information about processes and how the algorithm matches them to volume mixers
