 # Resolume Timecode Monitor
 
-This project allows multiple people to view the time remaining on the chosen clip.
+View the time left for a playing clip on multiple devices.
 
-More information coming soon.

+_This screenshot is from firefox on linux, but you can even view this on your phone._

+![server demo](demo2.jpg)
+_This is the server end of things, doesn't need to be run on the same device as Resolume_
+
+## How to use
+
+1. Open _resolume-timecode.exe_ and make sure that all the information in there is set correctly.
+2. Click _Start Server_
+3. Open your web browser to `http://localhost:8080` (or the IP of the device that's running this app plus `:8080`).
+4. Start playing a clip in Resolume.
+5. Profit.
+
+## Motivation
+
+When using Resolume for events where longer clips were being played, I found it annoying that the only way to find out
+the remaining time was to ask the guy in front of the laptop. So I decided to fix that.
+
+## How it works
+
+Resolume outputs the position of the clip head through OSC, by calculating how much time it took between the one message
+and the previous one, it's possible to calculate how long the clip is, and therefore how much time is left.
+Due to certain inconsistencies in the way this information is outputted, it's not as simple as it sounds.
+
+For the exact algorithm, check [main.js](https://github.com/chabad360/resolume-timecode/blob/master/main.js).
+
+## Known Issues
+
+- Playing a clip backwards just doesn't work. This is because of the way certain math is done, there is a relatively simple fix
+  I just haven't gotten to implementing it yet.
+- If a clip loops, the counter will stop. This is because I haven't yet figured out a good way to determine that a clip has looped,
+  without causing other issues.
+- Uses 60mb of RAM. Sorry, can't do much about that, at least it's better than a electron app.  
+
+## Building
+
+Because this is based on [fyne](https://fyne.io) it requires the use of _cgo_, so make sure you have some CC installed on your system.
+
+Just clone the repo and run `go build github.com/chabad360/resolume-timecode`.
