+
+
+This project generates and packages the static resources that Spring uses for document production.
+
+This project is based on [Antora](https://antora.org).
+
+
+## Development Quickstart
+
+This section offers a basic tutorial to teach you how to preview it locally, and bundle it for use with Antora.
+A more comprehensive tutorial can be found in the documentation at [docs.antora.org](https://docs.antora.org/).
+
+### Prerequisites
+
+To preview and bundle the Antora Spring UI, you need the following software on your computer:
+
+* [git](https://git-scm.com/) (command: `git`)
+* [Node.js](https://nodejs.org/) (commands: `node` and `npm`)
+* [Gulp CLI](http://gulpjs.com/) (command: `gulp`)
+
+### Preview the UI
+
+The Spring Antora UI project is configured to preview offline.
+The files in the `preview-src/` folder provide the sample content that allow you to see the UI in action.
+In this folder, you'll primarily find pages written in AsciiDoc.
+These pages provide a representative sample and kitchen sink of content from the real site.
+
+To build the UI and preview it in a local web server, run the `preview` command:
+
+```
+npm install
+gulp preview
+```
+
+You'll see a URL listed in the output of this command:
+
+```
+[12:00:00] Starting server...
+[12:00:00] Server started http://localhost:5252
+[12:00:00] Running server
+```
+
+Navigate to this URL to preview the site locally.
+
+While this command is running, any changes you make to the source files will be instantly reflected in the browser.
+This works by monitoring the project for changes, running the `preview:build` task if a change is detected, and sending the updates to the browser.
+
+Press `Ctrl`+`C` to stop the preview server and end the continuous build.
+
+### Package for Use with Antora
+
+If you need to package the UI so you can use it to generate the documentation site locally, run the following command:
+
+```
+gulp bundle
+```
+
+If any errors are reported by lint, you'll need to fix them.
+
+When the command completes successfully, the UI bundle will be available at `build/ui-bundle.zip`.
+You can point Antora at this bundle using the `--ui-bundle-url` command-line option.
+
+If you have the preview running, and you want to bundle without causing the preview to be clobbered, use:
+
+```
+gulp bundle:pack
+```
+
+The UI bundle will again be available at `build/ui-bundle.zip`.
+
+## Extensions to the UI
+
+### Related Documentation
+
+The UI presents a list of related documentation and that documentation can be filtered using two attributes:
+
+* page-related-doc-categories - The categories to be included in the related documentation
+* page-related-doc-projects - The project ids to be included in the related documentation
+
+For a complete listing of valid categories and ids view [related_projects.js](https://github.com/spring-io/antora-ui-spring/blob/main/src/helpers/related_projects.js)
+
+The configuration is typically specified in asciidoc attributes section of the `antora-playbook.yml`:
+
+```
+asciidoc:
+  attributes:
+    # Include the projects with the security category
+    page-related-doc-categories: security
+    # Include the projects with ids framework and graphql
+    page-related-doc-projects: framework,graphql
+```
+
+The Related Documentation links to the `All Docs...` page.
+To include this resource, ensure that the [antora-extensions](https://github.com/spring-io/antora-extensions/blob/main/README.adoc) is using 1.7.0+ and the [Static Page Extension](https://github.com/spring-io/antora-extensions/blob/main/README.adoc#static-page) is included.
