Update readme for social media account

[tkodev]

Is your feature request related to a problem? Please describe.
I was able to connect to my LGE/thinq account by removing all social media connections, and then adding a password and email, instead of removing all my devices and creating a new account.

Describe the solution you'd like
Dev team to confirm, and update the readme to tell people to:

• remove social media connections and add password / email to account.
• don't remov3 devices / create new account.

Describe alternatives you've considered
I thought about creating an account but using the same email, that requires messing with email changes on existing account too.

Additional context
None
