#31 #32 #24 - ask() in Chrome browser if available

#31 - ask() shows the question in terminal window. This is not intuitive if automation is running on the Chrome browser and a prompt appears in terminal window to ask for user input. Raising an issue to update behaviour to show prompt in Chrome browser, if it's available. PS - similar issue exists if chrome_browser = False and visual_automation = True. The terminal may not be in the foreground during the automation flow to be visible for user inputs. However, there isn't a consistent way to show SikuliX popup with focus across platforms. Thus KIV for now.

#32 - At present, if visual automation mode is not on and `snap('page.png', 'screenshot.png')` is used, there is no error message saying that `init(visual_automation = True)` is needed to use this. Raising an issue to show error message instead of hanging waiting for SikuliX response.

#24 - readme linking to RedMart online groceries example to automate re-adding all items to cart (to reschedule delivery, need to cancel and create new order manually)

 # API Reference
 
-[See sample Python script](https://github.com/tebelorg/TagUI-Python/blob/master/sample.py). For web automation, web element identifier can be XPath selector, CSS selector or the following attributes - id, name, class, title, aria-label, text(), href (in decreasing order of priority). There is automatic waiting for an element to appear before timeout happens, and error is returned that the element cannot be found. To change the default timeout of 10 seconds, use timeout() function.
+Check out [sample Python script](https://github.com/tebelorg/TagUI-Python/blob/master/sample.py) and [RedMart groceries example](https://github.com/tebelorg/TagUI-Python/issues/24).
 
-An element identifier can also be a .png or .bmp image snapshot representing the UI element (can be on desktop applications or web browser). x, y coordinates of elements on the screen work as well. Transparency (0% opacity) is supported in .png images, for eg using an image of an UI element with transparent background to enable clicking on an UI element that appears on different backgrounds on different occasions.

-A further example is an image of the window or frame (PDF viewer, MS Word, textbox etc) with the center content of the image set as transparent. This allows using read() and snap() to perform OCR and save snapshots for application windows, containers, frames, textboxes with varying content. Also for read() and snap(), x1, y1, x2, y2 coordinates pair can be used to define the region of interest on the screen to perform OCR or capture snapshot.
