 ## Installation
 
+### Bare Metal
+
 1. Setup a webserver capable of running PHP scripts.
     - ``php.ini`` file should have ``E_NOTICE`` reporting disabled, eg.:
         - ``error_reporting = E_ALL & ~E_NOTICE & ~E_STRICT``

 1. Install PHP dependencies.
     - ``composer install --no-dev``

+1. Run installation wizard: ``http(s)://<your_server_address>:<port>/install``
 1. Remove ``install/`` directory
 
+### Docker
+
+1. Prepare config file ``mkdir docker && cp config.php docker && cp includes/constants.php docker && sudo chown 33:33 docker/*.php``\
+The user and group id 33 here is the `www-data` user from `nginx:stable` and `php:7.3-fpm`, because it may have a different name on some hosts (for example, on archlinux it is `http`), use its id here to make sure it is available
+1. Prepare and edit environment config file ``cp example.env .env && vim .env``
+1. Build and run services ``docker-compose up -d --build``
+1. Run installation wizard: ``http(s)://<your_server_address>:<port>/install``\
+The port number should already be defined in ``.env``, unless you are using a reverse proxy such as nginx or traefik, then this should match the configuration in your reverse proxy.
+1. Initialize with the root user password and database name defined in the ``.env`` file, database host should be ``db``
+
 ## Updating from older versions
 
 1. Check [__Releases__ section](https://github.com/mdziekon/UniEngine/releases) to see if migration scripts have been provided between your current version and the latest version you want to upgrade to.
