+
+### How to Download
+You can download the release from here https://github.com/abhijitWakchaure/run-flogo-app/releases/latest
+
+### How to Use
+Make sure the binary you downloaded is executable, then you can directly run it as executable
+```
+./run-flogo-app
+```
+You can provide `-debug` flag to enable the debug logs in your flogo app, just make sure its the `first` argument to the program like this:
+```
+./run-flogo-app -debug
+```
+Also, you can pass command line arguments if your flogo app supports it; like this (the -debug flag is not mandatory for this):
+```
+./run-flogo-app -debug arg1 arg2 arg3
+```
+
+
+### The config file
+When the program starts it creates a config file with name `.run-flogo-app` in the same directory. It is a simple json file which looks like this:
+```
+{
+	"rfAppDir": "/home/abhijit/Downloads",
+	"rfAppPattern": "^.+-linux_amd64.*$"
+}
+```
+You can override the programs behavior by changing this file.
