+# Tech Docs Template Documentation
+
+[![Build Status](https://travis-ci.org/alphagov/tdt-documentation.svg?branch=master)](https://travis-ci.org/alphagov/tdt-documentation)
+
+This repository is used to generate the [documentation website for the Tech Docs Template][tdt-docs] and uses the template itself.
+
+The Tech Docs Template is a [middleman template][mmt] that
+you can use to build technical documentation websites using a GOV.UK style.
+
+## Before you start
+
+To use the Tech Docs Template you need:
+
+- [Ruby][install-ruby]
+- [Middleman][install-middleman]
+
+## Making changes
+
+To make changes to the documentation for the Tech Docs Template website, edit files in the `source` folder of this repository.
+
+You can add content by editing the `.html.md.erb` files. These files support content in:
+
+- Markdown
+- HTML
+- Ruby
+
+👉 You can use Markdown and HTML to [generate different content types][example-content] and [Ruby partials to manage content][partials].
+
+👉 Learn more about [producing more complex page structures][multipage] for your website.
+
+## Preview your changes locally
+
+To preview your new website locally, navigate to your project folder and run:
+
+```sh
+bundle exec middleman server
+```
+
+👉 See the generated website on `http://localhost:4567` in your browser. Any content changes you make to your website will be updated in real time.
+
+To shut down the Middleman instance running on your machine, use `ctrl+C`.
+
+If you make changes to the `config/tech-docs.yml` configuration file, you need to restart Middleman to see the changes.
+
+## Publishing changes
+
+Travis CI automatically publishes changes merged into the master branch of this repository.
+
+## Troubleshooting
+
+Run `bundle exec middleman build --verbose` to get detailed error messages to help with finding the problem.
+

+# Build a multipage site
+
+You can create a technical documentation site that splits its content across multiple pages.
+
+This is suitable for documentation sites that have too much content for the single page format.
+
+You should use the search feature [link] with multipage documentation sites.
+
+## Basic multipage
+
+You can split the content into multiple individual pages. An example is the [GOV.UK PaaS technical documentation](https://docs.cloud.service.gov.uk/).
+
+### Amend the tech-docs.yml file
+
+Add this to your project’s `tech-docs.yml` file, or set it to true if it is already there:
+
+```
+# Enable multipage navigation in the sidebar
+multipage_nav: true
+```
+
+### Repo folder structure
+
+A typical single page documentation repo has this folder structure:
+
+<br/><br/>
+![](/diagrams/Single_page.svg)
+<br/><br/>
+
+A basic multipage documentation repo can have this structure:
+
+<br/><br/>
+![](/diagrams/Basic_multipage.svg)
+<br/><br/>
+
+You must amend the documentation repo folder structure to reflect this structure.
+
+### Create multiple .html.md.erb files
+
+Basic multipage requires multiple `.html.md.erb` files in the tech docs repo __source__ folder.
+
+Each `.html.md.erb` file relates to one separate page within the tech docs, and references the markdown files in the associated folder.
+
+Additionally, the tech doc repo must have at least one `.html.md.erb` file in the __source__ folder named `index.html.md.erb`.
+
+The .html.md.erb files must not have the same name as the folders that the .html.md.erb files use partials refer to.
+
+For example, you cannot have a support.html.md.erb file that contains the partial `<%= partial 'support/contact_us' %>`.
+
+### Amend the multiple .html.md.erb files
+
+1. Add a weight argument and value to the title of each .html.md.erb file. This builds the structure of the multipage documentation.
+
+    For example:
+
+    ```bash
+    ---
+    title: "Product Technical Documentation"
+    ---
+    ```
+
+    becomes
+
+    ```bash
+    ---
+    title: "Product Technical Documentation"
+    weight: 10
+    ---
+    ```
+
+    Higher weights mean that the content is lower down in the documentation hierarchy. An easy way to remember this is to think “heavier pages sink to the bottom”.
+
+    For example, a single `.html.md.erb` file becomes multiple `.html.md.erb` files:
+
+    <div style="height:1px;font-size:1px;">&nbsp;</div>
+
+    |Single page|Multipage|
+    |:---|:---|
+    |---<br>weight: 10<br>title: "Product Technical Documentation"<br>---<br><br><%= partial 'documentation/index' %>|---<br>weight: 10<br>title: "Product Technical Documentation"<br>---<br><br><%= partial 'documentation/index' %>|
+    ||---<br>weight: 10<br>title: "Product Technical Documentation"<br>---<br><br><%= partial 'documentation/index' %>|
+    ||---<br>weight: 20<br>title: "Product Technical Documentation"<br>---<br><br><%= partial 'documentation/start' %>|
+    ||---<br>weight: 30<br>title: "Product Technical Documentation"<br>---<br><br><%= partial 'documentation/users' %>|
+
+    <div style="height:1px;font-size:1px;">&nbsp;</div>
+
+### Add H1 heading if required
+
+Add an H1 heading to either the `.html.md.erb` file or at the start of the first markdown file for each individual content page.
+
+If there is an H1 heading in both, you will see two H1s when the documentation site builds and renders in your internet browser.
+
+## Nested multipage
+
+You can split the content into multiple individual pages, and can have pages "nested" within one another. Two examples:
+
+- [GOV.UK PaaS technical documentation - Deploying services](https://docs.cloud.service.gov.uk/deploying_services/)
+- [GOV.UK Pay technical documentation - Switching to live](https://docs.payments.service.gov.uk/switching_to_live/#switching-to-live)
+
+### Amend the tech-docs.yml file
+
+Add this to your project’s `tech-docs.yml` file, or set it to true if it is already there:
+
+```
+# Enable multipage navigation in the sidebar
+multipage_nav: true
+```
+
+### Repo folder structure
+
+A typical single page documentation repo has this folder structure:
+
+<br/><br/>
+![](/diagrams/Single_page.svg)
+<br/><br/>
+
+A nested multipage documentation repo can have this structure:
+
+<br/><br/>
+![](/diagrams/Nested_multipage.svg)
+<br/><br/>
+
+You must amend the documentation repo folder structure to reflect this structure.
+
+### Create multiple .html.md.erb files
+
+Basic multipage requires multiple `.html.md.erb` files in the tech docs repo __source__ folder.
+
+Each `.html.md.erb` file relates to one separate page within the tech docs, and references the markdown files in the associated folder.
+
+Additionally, the tech doc repo must have at least one `.html.md.erb` file in the __source__ folder named `index.html.md.erb`.
+
+### Amend the multiple .html.md.erb files
+
+1. Add a weight argument and value to the title of each .html.md.erb file. This builds the structure of the multipage documentation.
+
+    For example:
+
+    ```bash
+    ---
+    title: "Product Technical Documentation"
+    ---
+    ```
+
+    becomes
+
+    ```bash
+    ---
+    title: "Product Technical Documentation"
+    weight: 10
+    ---
+    ```
+
+    Higher weights mean that the content is lower down in the documentation hierarchy. An easy way to remember this is to think “heavier pages sink to the bottom”.
+
+    For example, a single `.html.md.erb` file becomes multiple `.html.md.erb` files:
+
+    <div style="height:1px;font-size:1px;">&nbsp;</div>
+
+    |Single page|Multipage|
+    |:---|:---|
+    |---<br>weight: 10<br>title: "Product Technical Documentation"<br>---<br><br><%= partial 'documentation/index' %>|---<br>weight: 10<br>title: "Product Technical Documentation"<br>---<br><br><%= partial 'documentation/index' %>|
+    ||---<br>weight: 10<br>title: "Product Technical Documentation"<br>---<br><br><%= partial 'documentation/index' %>|
+    ||---<br>weight: 20<br>title: "Product Technical Documentation"<br>---<br><br><%= partial 'documentation/start' %>|
+    ||---<br>weight: 30<br>title: "Product Technical Documentation"<br>---<br><br><%= partial 'documentation/users' %>|
+
+    <div style="height:1px;font-size:1px;">&nbsp;</div>
+
+### Add H1 heading if required
+
+Add an H1 heading to either the `.html.md.erb` file or at the start of the first markdown file for each individual content page.
+
+If there is an H1 heading in both, you will see two H1s when the documentation site builds and renders in your internet browser.
+
+### Create folder for nested content .html.md.erb files
+
+Refer to the GOV.UK PaaS technical documentation repo [nested content folder](https://github.com/alphagov/paas-tech-docs/tree/master/source/deploying_services) as an example.
+
+1. Create a folder within the __source__ folder. This is where the `.html.md.erb` files for your nested content must live.
+
+1. Create an `index.html.md.erb` file within the nested content folder. This will be the "wrapper" for the nested content. It can refer to another content file through partials or have the content in itself.
+
+    Note that each `.html.md.erb` must have a weight value that preserves the overall hierarchy both within the nested content and compared to the other non-nested content.
+
+1. Create sub-folders for each nested page under the "wrapper".
+
+1. Create an `index.html.md.erb` file within each sub-folder. Each `.html.md.erb` file can refer to another content file through partials or have the content in itself.
+
+    Note that each `.html.md.erb` file must have a weight value that preserves the overall hierarchy both within the nested content and compared to the other non-nested content.
+
+### Add H1 heading if required
+
+Add an H1 heading to either the `.html.md.erb` file or at the start of the first markdown file for each individual content page.
+
+If there is an H1 heading in both, you will see two H1s when the documentation site builds and renders in your internet browser.
