Requirements

Before you install Evolution CMS 3, prepare both the runtime requirements and the project information the installer will ask for.

Runtime Baseline

• PHP 8.3 or newer
• a supported database and working credentials
• a writable environment for cache and generated files
• a web server or local stack that can serve the project correctly

For CLI Installation

• Composer 2.x
• shell access
• network access if the installer must download releases or dependencies

Information to Prepare

• database host, database name, database user, and database password
• site URL and manager path expectations
• admin account credentials
• filesystem path and deployment target if you are not installing locally

Before You Start

If you are updating an existing site instead of creating a new one, make a full file and database backup first. See Backups and Updating Evolution.
