 ## description
 
 Go Manager is a program that watches your package binaries and if they're not the same version of your installed go version, it rebuilds the packages.
+By default it is ran every 24 hours.
+It does not use fnotify or similar.
+It's a simple tool which checks the current Go version vs the version of the complied binaries.
 
-all commands **must** be ran as root
+You **MUST** be root to run all commands
+
+## scenario
+
+You have go projects which you `git clone` and `go build`.
+You can't be arsed to keep the built binaries up to date, manually, every time a new Go version is released.
+Gomanager does this job for you, periodically.
