 ### Limitations:
 
+ * Subsites are usually accessed via their own separate domains.
+   In order to allow efficient cross-subsite CMS editing,
+   they can also be accessed via URL parameters rather than domain maps.
+   This can weaken domain-specific security controls in your environment
+   such as domain-specific IP whitelists, firewall rules or business logic.
  * Each subsite domain name has to be set up on the server first, and DNS records need to be updated as appropriate.
  * A subsite cannot use a different codebase as the main site, they are intrinsically tied
  	* However, you can remove page types from a subsite when creating the subsite - [see the setup documentation for further details](docs/en/userguide/set_up.md)

 *  Once you've created a subsite, you'll see a "Create Subsite Domain" button, hit that button to enter a domain or subdomain for your subsite. This will determine the URL of your website.

 *  Go to the "Pages" section of the CMS.  In the top-left above the menu, you'll see a dropdown listing the two subsites - "Main site" is the original site that you had before you installed the subsites module.  Select your new subsite, and the site content tree will be changed.  It should be empty at this stage.
 *  Add a page - change its title to "Home", and its URL Segment will be changed to "home".  Save the page.
-*  Update your DNS and, if necessary, your webserver configuration, so that your subdomain will point to the SilverStripe installation on your webserver.  Visit this new subdomain.  You should see the new subsite homepage.

+
+#### Cascading themes
+
+In Silverstripe 4 themes will resolve theme files by looking through a list of themes (see the documentation on 
+[creating your own theme](https://docs.silverstripe.org/en/4/developer_guides/templates/themes/#developing-your-own-theme)).
+Subsites will inherit this configuration for the order of themes. Choosing a theme for a Subsite will set the list of 
+themes to that chosen theme, and all themes that are defined below the chosen theme in priority. For example, with a
+theme configuration as follows:
+
+```yaml
+SilverStripe\View\SSViewer:
+  themes:
+    - '$public'
+    - 'my-theme'
+    - 'watea'
+    - 'starter'
+    - '$default'
+```
+
+Choosing `watea` in your Subsite will create a cascading config as follows:
+
+```yaml
+themes:
+  - 'watea'
+  - '$public'
+  - 'starter'
+  - '$default'
+```
+
+You may also completely define your own cascading theme lists for CMS users to choose as theme options for their 
+subsite:
+
+```yaml
+SilverStripe\Subsites\Service\ThemeResolver:
+  theme_options:
+    normal:
+      - '$public'
+      - 'watea'
+      - 'starter'
+      - '$default'
+    special:

+### How do Subsite domains work with Fluent domains?
+
+The Subsites module and Fluent translation module both provide the concept of defining "domains" and let you
+configure the host name for it. This functionality is essentially performing the same duty in both modules.
+
+In the "URL segment" field for CMS pages, both Subsites and Fluent will add their context to the value. If you
+have a Subsite domain configured but no Fluent domain, Fluent will respect the existing domain and add its
+locale context to the value. If you have a Subsite domain configured and a Fluent domain configured, Fluent will
+use its own domain host name value, and the Subsite domain value will be lost. For this reason, you will need
+to ensure that you use the same host name in both Subsite and Fluent domain entries.
