 Merged is designed for developers to give limited editing facilities
 to users. As with rails, there is great flexibility how this can be
-achieved, a basic example below.
-
-## Concepts
-
-Merged has simple but powerful concepts and structures to define
-the interactions users may have.
-
-### Page
-
-The core entity that may be edited is a Page. Pages contain Sections
-(below) in a way defined by developers.
-
-A Page has a type, different types may define different layouts, or rather types of Sections they may include.
-
-A page has a name which is it's Url, Merged is not designed for nesting currently.
-
-All data that users change is stored in the Pages' Yaml, which get
-committed and __merged__ to propagate to the site.
-
-A Page also has data, attributes and options, see below.
-
-### Sections
-
-Merged itself defines many styles of sections, and off course
-developers may define more.
-For example a Header with text is a section, a hero section is a section, and a card section is a different style.
-
-The only defining characteristic of a section is really that it is full width, and it has a template that renders the content.
-
-A Page may contain as many sections as the Page definition allows.
-
-A Section in turn may contain cards.
-
-Like a Page, a Section may have options.
-
-### Cards
-
-Cards, as in general css lingo, are usually smaller html boxes,
-usually contained in a grid (defined by the Section). But they may
-be form fields, or features (svg).
-
-Cards have data and options like the other elements.
-
-### Image
-
-Merged also manages images, adding deleting, renaming, even a small editor.
-Images are stored in the assets folder. With the Pages, Sections and Cards they
-define the content that users can change.
-
-Images merge into the upstream in the same way as the pages, through
-git actions (partially done by Merged)
-
-### Change (-sets)
-
-As data is in files, all change happens by git.
-Merged partially manages this, by making changes visible to the
-users, ie what Pages and Images were added/removed or edited.
-Merged can commit and in the future maybe even push.
-
-Merged requires a user to be logged in and will log all changes, meaning
-change times and the email of the editor. The last change is displayed in
-the ui for auditing purposes.
-
-## Basic setup
-
-A developer set up a machine on a intranet/lan. Ie access is
-restricted by physical access.
-
-The machine is set up as a developer machine, on a "feature" branch.
-A User may use the machine to edit and commit and push (the branch).
-
-The developer reviews, merges changes and deploys.
+achieved, see wiki for more details.
 
 ## Installation
 
-Add to your Gemfile:
-
-```ruby
-gem "merged" , git: "https://github.com/HubFeenixMakers/merged"
-```
-
-And then bundle:
-```bash
-$ bundle
-```
-
-Mount engine in routes for editing (possibly not in production).
-
-```ruby
-mount Merged::Engine => "/merged" unless Rails.env.production?
-```
-
-Create route to serve content.
-```ruby
-get ":id" , to: "merged/view#page" , id: :id
-```
-
-If Merged served the root:
-```ruby
-root "merged/view#page" , id: 'index'
-```
-
-### Stylesheets
-
-#### Apps not using tailwind
-
-Include merged stylesheet to your layout or asset
-pipeline.
-
-```
-= stylesheet_link_tag "application"
-= stylesheet_link_tag "merged/merged"
-```
-
-#### Apps using tailwind
-
-If you use tailwind with the tailwind gem, you need to edit the tailwind config.
-
-Basically it is impossible to have two tailwind generated stylesheets, so your app needs to pick up the merged styles. This can be configured like so:
-
-```
-const output = execSync('bundle show merged', { encoding: 'utf-8' });
-const fullname = output.trim() + '/app/**/*.{haml,html,rb}' ;
-
-
-module.exports = {
-  content: [
-    fullname ,
-    .... as before
-  ]
-```
-
-Also, merged overrides some tailwind styles (especially prose/markdown),
-so if you want to use markdown i suggest importing the `merged/tailwind_styles` into your application.css. This is pure css, and does not
-need to be processed by tailwind.
-
-
-## Developers
-
-### Styles
-
-Developers should look at the predefined styles. These are found in
-merged gem /config/merged/**style.yml
-
-And on a running app http://localhost:3000/merged/styles/index
-
-### Section Views
-
-These are under app/views/merged/views/sections/*haml
-and the name of the file matches the section_style entry
-
-Developers may define more section styles, but must provide the partials to render them.
-
-### Card Views
-
-These are under app/views/merged/views/cards/*haml
-and the name of the file matches the card entry.
-
-Developers may define more card styles, but must provide the partials to render them.
-
-### Options
-
-Option definitions (also found under style dir) are common between elements.
-Options may be added and then used in the view partials. Many common ones (background,
-color) and many more are already defined.
-
-To make the partials more dry, Helpers are defined in OptionsHelper
