1. PHP REQUIREMENT LINK : https://docs.flarum.org/install/#server-requirements (We have kept PHP 8.2, since extension manager requires PHP 8.2 dependencies via composer, make manual install on same)
2. [IMP] Download the package named "flarum-v1.x-php7.3" from https://docs.flarum.org/install/#installing-by-unpacking-an-archive as it includes extention manager. Suggested by vendor.
(It seems that these zips aren't updated frequently as per Github versions. Hence, from 1.8.17 we use composer method)
3. Remove sql insert from `[[dbprefix]]access_tokens` and adjust AUTO_INCREMENT.
4. Kept version as 1.0.4 in info.xml as it shows 1.0.4 in admin panel dashboard, in `[[dbprefix]]settings` table and in /vendor/flarum/core/src/Foundation/Application.php (though composer install shows Installing flarum/flarum (v1.0.0))
5. Copy public/assets/fonts folder from manual to zip as it is not generated after install. The 'fonts' folder can be checked by download via url mentioned in /vendor/composer/installed.json under "name": "components/font-awesome" , i.e https://api.github.com/repos/components/font-awesome/zipball/{{reference-hash}}. 
Check diff only with the /webfonts/ folder to verify whether structure is correct.
6. Check for symlinks in every version.
7. We have used .htaccess to redirect to /public folder.
8. We won't provide upgrade in this because we have launched the package with extension manager and it can directly be upgraded through it.
