Thanks a lot.
Yes, I can explain briefly.
I started the visa application from Cic myaccount page.
They ask different questions and create a customized checklist.
I filled all forms and supporting documents.
I attached each one in proper section online.
Finally, it directed me to pay the fee.
I paid the fee and did my electronic signature.
Visa fee was 100$ and Biometrics was 85$.
After an hour I received confirmation of application and letter requesting biometrics. Got everything done next day.
Then complete silence for a week and received approval today
