 ## Making Linux builds
 
+### Background Information

 The key thing is, to run the deploy script which should copy
 dependencies of application itself to lib folder, but we are still
 left with the dependencies of `libqxcb.so` and those can be checked
@@ -9,3 +11,18 @@ What I found was libQDBUS was missing from the list of libraries being
 copied and hence that must be copied for making the deployment work.

+### Using Ruby script here to make a linux build
+
+First navigate to the directory where local binary has been built. In many cases it
+would be somewhere - `$HOME/build-RbkitClient-Desktop-xxx` or whatever is your location
+of shadow build.
+
+1. Go to `rbit-app` folder of shadow build directory and check if you have `RbkitClient` executable present.
+2. Once there, specify using script here to make a build:
+
+```
+~/nomads/rbkit-client/tools/deployqt.rb RbkitClient
+```
+
+This should give us a `rbkit.tar.gz` which can be now deployed on any Linux.
