 To create the github_token file, we take this approach:
 - Find the angular-builds:token in http://valentine
-- Go inside the ngcontainer docker image so you use the same version of openssl as we will at runtime: `docker run --rm -it angular/ngcontainer`
+- Go inside the CircleCI default docker image so you use the same version of openssl as we will at runtime: `docker run --rm -it circleci/node:10.12`
 - echo "https://[token]:@github.com" > credentials
 - openssl aes-256-cbc -e -in credentials -out .circleci/github_token -k $KEY
 - If needed, base64-encode the result so you can copy-paste it out of docker: `base64 github_token`

 This section describes how each of the aforementioned sub-tasks is accomplished:

+1. **Receive notification from CircleCI of a completed build**
 
   CircleCI is configured to trigger a webhook on our preview-server whenever a build completes.
   The payload contains the number of the build that completed.
 
-1. **Verify that the build is valid and download the artifact.**
+2. **Verify that the build is valid and can have a preview.**
 
    We cannot trust that the data in the webhook trigger is authentic, so we only extract the build
    number and then run a direct query against the CircleCI API to get hold of the real data for
    the given build number.
 
-   If the build was not successful then we ignore this trigger. Otherwise we check that the
-   associated github organisation and repository are what we expect (e.g. angular/angular).
+   We perform a number of preliminary checks:
+   - Was the webhook triggered by the designated CircleCI job (currently `aio_preview`)?
+   - Was the build successful?
+   - Are the associated GitHub organisation and repository what we expect (e.g. `angular/angular`)?
+   - Has the PR touched any files that might affect the angular.io app (currently the `aio/` or
+     `packages/` directories, ignoring spec files)?
 
-   Next we make another call to the CircleCI API to get a list of the URLS for artifacts of that
+   If any of the preliminary checks fails, the process is aborted and not preview is generated.
+
+3. **Download the build artifact.**
+
+   Next we make another call to the CircleCI API to get a list of the URLs for artifacts of that
    build. If there is one that matches the configured artifact path, we download the contents of the
    build artifact and store it in a local folder. This download has a maximum size limit to prevent
    PRs from producing artifacts that are so large they would cause the preview server to crash.

+<h1 class="no-toc">CLI Command Reference</h1>
+
+The Angular CLI is a command-line interface tool that you use to initialize, develop, scaffold, and maintain Angular applications. You can use the tool directly in a command shell, or indirectly through an interactive UI such as [Angular Console](https://angularconsole.com).
+
+## Installing Angular CLI
+
+Major versions of Angular CLI follow the supported major version of Angular, but minor versions can be released separately.
+
+Install the CLI using the `npm` package manager:
+<code-example format="." language="bash">
+npm install -g @angular/cli
+</code-example>
+
+For details about changes between versions, and information about updating from previous releases, 
+see the Releases tab on GitHub: https://github.com/angular/angular-cli/releases
+
+## Basic workflow
+
+Invoke the tool on the command line through the `ng` executable. 
+Online help is available on the command line. 
+Enter the following to list commands or options for a given command (such as [generate](cli/generate)) with a short description.
+
+<code-example format="." language="bash">
+ng help
+ng generate --help
+</code-example>
+
+To create, build, and serve a new, basic Angular project on a development server, go to the parent directory of your new workspace use the following commands:
+
+<code-example format="." language="bash">
+ng new my-first-project
+cd my-first-project
+ng serve
+</code-example>
+
+In your browser, open http://localhost:4200/ to see the new app run. 
+When you use the [ng serve](cli/serve) command to build an app and serve it locally, the server automatically rebuilds the app and reloads the page when you change any of the source files.
+
+## Workspaces and project files
+
+The [ng new](cli/new) command creates an *Angular workspace* folder and generates a new app skeleton. 
+A workspace can contain multiple apps and libraries.
+The initial app created by the [ng new](cli/new) command is at the top level of the workspace. 
+When you generate an additional app or library in a workspace, it goes into a `projects/` subfolder.
+
+A newly generated app contains the source files for a root module, with a root component and template. 
+Each app has a `src` folder that contains the logic, data, and assets.
+
+You can edit the generated files directly, or add to and modify them using CLI commands. 
+Use the [ng generate](cli/generate) command to add new files for additional components and services, and code for new pipes, directives, and so on. 
+Commands such as [add](cli/add) and [generate](cli/generate), which create or operate on apps and libraries, must be executed from within a workspace or project folder.
+
+* See more about the [Workspace file structure](guide/file-structure).
+
+### Workspace and project configuration
+
+A single workspace configuration file, `angular.json`, is created at the top level of the workspace. 
+This is where you can set per-project defaults for CLI command options, and specify configurations to use when the CLI builds a project for different targets.
+
+The [ng config](cli/config) command lets you set and retrieve configuration values from the command line, or you can edit the `angular.json` file directly. 
+Note that option names in the configuration file must use [camelCase](guide/glossary#case-types), while option names supplied to commands can use either camelCase or dash-case. 
+
+* See the [complete schema](https://github.com/angular/angular-cli/wiki/angular-workspace) for `angular.json`.
+<!-- * Learn more about *configuration options for Angular(links to new guide or topics TBD)*. -->
+
+
+## CLI command-language syntax
+
+Command syntax is shown as follows:
+
+`ng` *commandNameOrAlias* *requiredArg* [*optionalArg*] `[options]`
+
+* Most commands, and some options, have aliases. Aliases are shown in the syntax statement for each command.
+
+* Option names are prefixed with a double dash (--). 
+    Option aliases are prefixed with a single dash (-). 
+    Arguments are not prefixed.
+    For example: `ng build my-app -c production`
+
+* Typically, the name of a generated artifact can be given as an argument to the command or specified with the --name option. 
+
+* Argument and option names can be given in either 
+[camelCase or dash-case](guide/glossary#case-types). 
+`--myOptionName` is equivalent to `--my-option-name`.
+
+### Boolean and enumerated options
+
+Boolean options have two forms: `--thisOption` sets the flag, `--noThisOption` clears it.  
+If neither option is supplied, the flag remains in its default state, as listed in the reference documentation.
+
+Allowed values are given with each enumerated option description, with the default value in **bold**.
+
+### Relative paths
+
+Options that specify files can be given as absolute paths, or as paths relative to the current working directory, which is generally either the workspace or project root.
+
+### Schematics
+
+The [ng generate](cli/generate) and  [ng add](cli/add) commands take as an argument the artifact or library to be generated or added to the current project. 
+In addition to any general options, each artifact or library defines its own options in a *schematic*. 
+Schematic options are supplied to the command in the same format as immediate command options.
