How to store additional data like phone, location, and address while signing up.
do i have to use User Preference,
TL;DR
To store additional data like phone, location, and address while signing up, you can use the User Preference feature. This allows you to store small amounts of data with a limit of 64KB in total size. To implement this, create a function that listens to the user creation event and use the `updatePrefs` function to store the data. You can also use the `getPrefs` function to retrieve the preferences and the `updatePrefs` function to update them later on. If the amount of data exceeds the 64KB limit, it is recommended to create another collection. 
If its just small amount of information, then yes use the User Preference. But the User Preference has limit of 64KB for the total size, so if it bigger then that creating anouthr collection would be the best
yes its a small amount of data like three or four field with 50 words each
So User Preference well suit you
as i go through doc but not found how to implement.
To get the preference https://appwrite.io/docs/client/account?sdk=web-default#accountGetPrefs
To update https://appwrite.io/docs/client/account?sdk=web-default#accountUpdatePrefs
So you would do something like this
TypeScript
const prefs = await account.getPrefs();
prefs['phone'] = '1234';
await account.updatePrefs(prefs);
but how to create while sign up
For that create a function the listen to the event of user creation and then do something like this
TypeScript
users.updatePrefs('[USER_ID]', {});
