Installing CWM without android sdk Any software that'll help installing CWM

Is there any software that will allow me to install CWM other than android sdk.
For some reason I am not able to install android sdk.
You can flash CWM or TWRP directly from your phone using an app called Rashr. You can also choose to download the IMG files if you don't have them. Make sure you flash a compatible and stable version of the recovery.
