1. PHP REQUIREMENT LINK : https://docs.flarum.org/install/#server-requirements
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.
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.
