How to achieve with standard cropped Image with ImageCrop

Hi I am getting stuck with implementing ImageCrop module (after a problematic installation). Case is that Users could upload a profile picture, I want the users should select an area of their picture of 150px by 150px square (no smaller no bigger). Could you give me some steps to achieve this with ImageCrop pls? ( (should I use the standard upload file to upload first the picture? and which microflow could i use for this action from the ImageCrop?)

The ImageCrop module has a UseMe folder with an example page in it. If you try to recreate what is done from the start of this page you should be able to implement it yourself wherever you want to.

If you look at the page CropImage_Upload you'll see you first need to upload the picture before you can crop it.
