Multisite allows you to control a "network" of websites using one single WordPress instance. The Themosis framework is compatible with the multisite feature of WordPress. This guide will help you to start a new multisite project from scratch using the Themosis framework.
The following steps cover both sub-domains and sub-folders multisite installation.

.env.local.php file and add your database credentials (supposing you already defined your database) and the default URL for your project. Be sure to let the
/cms URI in the
The default URL will be your main website URL in your multisite installation.
For this example, our
.env.local.php environment file will look like this:
<?php /*----------------------------------------------------*/ // Local environment vars /*----------------------------------------------------*/ return [ 'DB_NAME' => 'wpmu', 'DB_USER' => 'root', 'DB_PASSWORD' => '', 'DB_HOST' => 'localhost', 'WP_HOME' => 'http://wpmu.dev', 'WP_SITEURL' => 'http://wpmu.dev/cms' ];

environment.php file and specify your local environment server hostname or define an anonymous function (Closure) to let the framework know which environment file to load. Check the environment guide for more detailed explanations: http://framework.themosis.com/docs/environment/
Now that your environment is setup, look after the
shared.php file located in the
config directory and open it.

Click the Install button.
On some installation you might get a warning message with a
timeoutissue when WordPress tried to access a random sub-domain address. Don't worry, this is because you haven't a wild-card defined for sub-domains.

shared.php (and not wp-config.php) file and add the mentioned constants. In our example, you'll add those lines:
define('MULTISITE', true); define('SUBDOMAIN_INSTALL', true); // Set to false if you selected the "Sub-directories" installation. define('DOMAIN_CURRENT_SITE', 'wpmu.dev'); // Main domain. Same as defined in your .env file without the http protocol. define('PATH_CURRENT_SITE', '/'); define('SITE_ID_CURRENT_SITE', 1); define('BLOG_ID_CURRENT_SITE', 1);
Then open the
.htaccess file and copy/paste the code shown in your WordPress screen.
Finally click the small Log in link at the bottom of your WordPress network installation screen to re-connect and log in back to the administration.
By default the
themosis-theme won't be available inside the
Appearance->Themes panel. If you visit that screen you should see an admin message telling that WordPress is looking after the twenty-something theme.

themosis-theme available, we have to "network activate it".
On the top left of your screen, go to My Sites > Network Admin > Themes
themosis-theme is listed. Click on the Network Enable link in order to make your theme available on your network.

cms/ URI, note that all requests work.
The issue is not a framework one but a WordPress core one. This might be fixed on a future update of WordPress. A ticket has been opened on WordPress trac, don't hesitate to contribute to it so it can be merged into core.
In order to fix the
