The flow of group creation must be intuitional to user

[Jin]

Description:
Telegram has no hints to let the user know how to create a group chat,
when user select one contact in the "New Group" page,
should have tips let user know how to show the text field to edit chat title,
and finish the group creation process.

Reproduce Steps:
    a) Launch Telegram
    b) Click "New Group" in menu
    c) Select one contact
    d) Observe the UI

Expected Result:
Popup a hint to let our users know it must have two persons to create a group,
or
show the "Chat title" bar after one person selected but mark the top right tick as gray-out to train our users.

Actual Result:
No any hints/tips after one person selected.

Occurrence:
10/10 (100%)

Also, it is unclear to me why it takes 3 people to initialise a group, if i wish to create a group with one of my contacts, so that contact can invite one of their contacts.... I cannot.

I understand that this is possible on yhe android client.
