 ### 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

  * The only code a developer can edit between subsites is the theme
  * The separation between subsites in the CMS needs to be seen as cosmetic, and mostly applicable to the "Pages" and "Files" sections of the CMS.
- * All subsites run in the same process space and data set. Therefore if an outage affects one subsite it will affect all subsites, and if bad code or hardware corrupts one subsite's data, it's very likely that it has corrupted all subsite data.

+ * It is not currently possible to backup or restore the data from a single subsite.
  * It is awkward (but not impossible) to have separate teams of developers working on different subsites - primarily because of the level of collaboration needed. It is more suited to the same group of developers being responsible for all of the subsites.
 
 If more isolation of code, security, or performance is needed, then consider running multiple separate installations (e.g. on separate servers).

 *  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.  For example, if your site is running on `http://localhost/mysite`, and you set the subdomain to "subsite", then your subsite will be accessible on `http://subsite.localhost/mysite`
 *  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.

+
+#### 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:
+      - 'my-theme'

-## Introduction
+# Subsites
 
-Subsites is a module to allow you manage multiple related sites from a single CMS interface.
-
-When Subsites is installed your existing site is defined as the main site, you will be then be able to create related 
-subsites under the main site. 
-
-
-So for example you may have an international presence and you want to create a subsite for a country where you do 
-business which is geared just for that market.
-You could create a subsite for this and have all information related to that country kept under this subsite, you can 
-also set up a subdomain for this site.
-
-
-One of the benefits of subsites is that it is easy to copy pages between the subsites and you have access to all of 
-the assets across all of the subsites.
-
-Subsites is not for running unrelated websites on a single SilverStripe instance so if 2 sites have different vhosts
-you will not be able to run them with Subsites on a single SilverStripe instance.
-
-With Subsites you can set up users to have access to all subsites or just a selection of subsites.
-
-
-## Common subsite uses
-Subsites can be used for various different reasons here are some of the common ones
-
-* Setting up a subsite for a small campaign so for example a clothing company may set up a summer or winter subsite to
-market just that season of clothing.
-* Locking down a particular subsite you may create a particular department like recruitment who would have access to
-create and edit pages for their particular subsite but they would not be able to modify the main website.
-* Running sub-domains on a single SilverStripe instance, with subsites if a sub-domain is pointing to the same instance
-and has been setup correctly you can manage this via a single CMS instance.
-* Subsites can not be used to run multiple websites on a single instance.
-Subsites does not allow you to run multiple domains/vhosts on a single instance.
-
-## Access
-
-Access to certain subsites can be limited to administrators based on the groups they are in.
-So for example if you had a couple of subsites you could create a group for each subsite and then specify that the 
-group had access to all subsites or just a specific subsites.
-To access this functionality go to
-
-
-Security -> Groups
-
-![alt text](_images/subsite-admin-security-group.png "Groups")
-
-Select the group you want to modify and then go to the Subsites tab
-
-You can also limit the page types that are available for a subsite (but not the main site).
-This can be done via accessing the particular subsite you want to amend via the Subsite admin section, underneath the
-Subsite theme will be a link called 'Disallow page types?' clicking on that link will display a list of checkboxes for
-all of the page types which can be selected to disable that page type for the subsite you are editing.
-This is useful when you create a content editor and you do not want them to be able to add certain page types.
-
-## Theme
-A theme is group of templates, images and CSS for the look of a website.
-When you are using Subsites you may have different themes installed for your site so you could apply different
-themes for each subsite.
-
-## Page types
-Page types refer to the type of pages that can be set up on a site.
-A page type will have certain features and functionality some examples on SilverStripe would be 'Page', 'HomePage'
-and 'ErrorPage' these all differ to each other in what they would be used for so you would use Page for any pages
-underneath the HomePage.
-
-
-You would only have one HomePage for your site and you may have some logic to only allow you to create one of these
-pages, ErrorPage would only be used for error pages and would be designed to be very minimal to work in situations
-where the site is experiencing difficulties like no DB access.
-
-
-You can set up a Subsite to only work with certain page types so you may have a page type with a contact form for a 
-particular department so you may set up a new subsite and not allow that page type to be used on a particular subsite.
-You will not be able to filter Page Types for the main site.
-
-## Assets
-Assets are files that have been uploaded via the CMS.
-It is suggested to use a naming convention for files designated to be used on a particular subsite or to create folders
-for each subsite to help organise them.

+
+The Subsites module and Fluent translation module both provide the concept of defining "domains" and let you

+
+In the "URL segment" field for CMS pages, both Subsites and Fluent will add their context to the value. If you

+
+## Understanding subsites
+
+Subsites is a module to allow you manage multiple related sites from a single CMS interface. Because all sites run on a single installation of SilverStripe, they can share users, content and assets. They can all use the same templates, or each use different ones.
+
+When Subsites is installed your existing site is defined as the main site, you will be then be able to create related subsites under the main site. 
+
+So for example you may have an international presence and you want to create a subsite for a country where you do business which is geared just for that market. You could create a subsite for this and have all information related to that country kept under this subsite, you can also set up a subdomain for this site.
