What you'll see at first start
Newcomers should first obtain the APK file, then grant permission and install; this part in the bdtk1 Guide is most important here.
Many Dhaka users complete the quick setup with bKash; Nagad and Rocket also work, so there is no separate hassle.
Once logged in, locate the menu, profile and support, then proceed slowly; that is wise.
