5. Once installed you will not see Google Play store app. You can either install it via Gapps (search for it) OR download the following MIUI supermarket app (attached below)
6. Move the supermarket.apk to your SD card and install it. Once installed, open it and in the search bar write google. You will see lots of app but none showing Google play store.
