Add custom field in M2 registration form (Basic) WPMU Membership2

1-instructions.txt

### We are adding telephone number as custom field

1. Go to /wp-content/plugins/membership/app/view/templates/ and copy all 4 files.
2. Go to /wp-content/themes/YOUR_CURRENT_THEME/ and create a new folder called membership2, then paste all 4 files inside the new created membership2 folder
3. Open membership_registration_form.php and put the following: membership_registration_form.php
4. Now open the membership_account.php file and put the following: membership_account.php
5. Finally need to add some code: mu-plugin.php

## You can add those codes in your functions.php in the theme, 
## if you think your theme won’t be changed. Otherwise mu-plugins is the best solution. 
## To use mu-plugins, go to /wp-content/ and find the folder with name 'mu-plugins'. 
## If there is no folder in that name, then create a folder, name it 'mu-plugins', create a file inside that, 
## give any name you like and paste the code in there. You don't need to activate that plugin. 
## Mu-plugins means must use plugins, so it will be activated automatically always. 
## If you use mu-plugins then add a php start tag at the beginning of the code.
