php composer.phar require nikosid/yii2-cloudinary "dev-master"
./composer.json has been updated

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for nikosid/yii2-cloudinary dev-master -> satisfiable by nikosid/yii2-cloudinary[dev-master].
    - nikosid/yii2-cloudinary dev-master requires cloudinary/cloudinary_php dev-master -> satisfiable by cloudinary/cloudinary_php[dev-master] but these conflict with your requirements or minimum-stability.

@hdkcreative, what is minimum-stability level on your project?
And when you get this error not fount?
I've just tested it - downloaded yii2-basic, then installed this library by php composer.phar require nikosid/yii2-cloudinary "dev-master" and it works.
I've corrected README.md a little, maybe it help with your error
