#Getting started

k0smos is a modular, tenant-aware application base. This guide covers the shortest safe path from checkout to a working local installation.

#Requirements

• PHP 8.5 with the extensions declared in composer.json
• Composer 2
• A supported database driver: SQLite, MariaDB/MySQL, or PostgreSQL
• Node.js only when rebuilding theme assets

#Install the application

composer install
composer app:install

The installer creates the application structure and runs the required migrations. Tenant configuration identifies the database and the enabled runtime modules.

#Next steps

Continue with Administration to configure modules and access. For background processing, read Queue operations.

Never point automated tests at a runtime tenant database. Use isolated test databases and fixtures.
