1. make package by extracting zip of wa-sources
2. PHP REQUIREMENT LINK : https://developers.webasyst.com/installation/ and also check /wa-installer/lib/config/requirements.php
3. Keep default timestamp and regtime values in `wa_widget_params` table.
4. From sql we remove 'token_data', 'waid_endpoints_sync_time, updates_endpoints_sync_time, services_endpoints_sync_time entry' from 'wa_app_settings' since it is made when we visit 'Installer'(from admin panel). Remove inserts from 'wa_log' table as well. Remove 'waid_credentials' from 'wa_app_settings', This is regenerated from admin panel under Settings->Enable Webasyst Id.
Also remove insert from 'wa_contact_auths' as it is created again post login.
5. Important : We have configured .htaccess in the root folder i.e add following changes at the end of the file(Required for Configuring Apache + FastCGI for Webasyst https://developers.webasyst.com/docs/installation/tips/apache-fastcgi/) :
<ifmodule mod_rewrite.c>
    RewriteEngine On
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
</ifmodule>
This is needed for apps to work correctly on Apache + FastCGI and since we encountered error on 'CRM' tab i.e 'Authorization issue detected' and it was fixed by adding the above lines to .htaccess in root as mentioned in their docs.
