-# TDD Example Drupal 8 Blog Module
+# TDD Dublin demo module
 
-A demo module to accompany my [TDD - Test Driven Drupal][0] talk, originally for DrupalCamp
+A demo module to accompany my [TDD Test Driven Drupal][0] talk at DrupalCamp
 Dublin 2017.
 
-In order to see my workflow of writing comments first, converting them into
-failing tests, and then writing the implementation code to make them pass, you
-can see the [list of previous commits][1] and see each step taken, as well as
-[the tags][2] that identify the commits when each failing test is added and
-then subsequently passes.
-
 ## Acceptance Criteria
 
 This module will be used to demonstrate how to take a test-driven approach to
 develop a module to the following acceptance criteria:
 
 - As a site visitor
-- I want to see a list of all published blog posts at `/blog`
-- Ordered by post date, with the newest posts first
-
-## Installation
-
-Within your Drupal 8 site:
-
-```bash
-cd modules
-git clone git@github.com:opdavies/drupal-module-tdd-blog.git tdd_blog
-```
+- I want to see a list of all published pages at `/pages`
+- Ordered alphabetically by title

 You can use PHPUnit's `--filter` option to specify a single test method to run,
 rather than all of the tests within the module. For example:
 
 ```
-vendor/bin/phpunit -c core modules/custom/tdd_blog --filter=testOnlyPublishedPagesAreShown
+../vendor/bin/phpunit ../modules/custom/tdd_dublin --filter=testOnlyPublishedPagesAreShown
