-0. Start tracking dependency updates
-  - Everyone on your team should create an account on Gemnasium (gemnasium.com)
-  - Add your team's API repo to Gemnasium (gemnasium.com) for dependency monitoring
-  - [Add a Gemnasium badge](http://support.gemnasium.com/knowledgebase/articles/560841-how-to-add-the-gemnasiun-badge-to-my-project-readm) to your repo's README (which you should also update every week)
 1. Write migrations to create relational tables for your project
   - Identify *at least two tables* you will need for your project, except for a user table
   - Add gems to `Gemfile` and `config/environments.rb` as we saw in class
   - Create migration files in `db/migrations/` to create your tables
-  - Create a `Rakefile` with `db:migration` and `db:reset` tasks
-  - Create `db/dev.db` and `db/test.db` Sqlite databases for the development and test environments
+  - Create a `Rakefile` with a `db:migrate` task
+  - Create `db/dev.db` and `db/test.db` Sqlite databases for the development and test environments using your migrations
   - Add `db/*.*` to your `.gitignore` to ignore the databases, but not your migrations
   - Be careful to follow the plural/singular conventions of Sequel

-2. Create Models and play with your new database!
+2. Create models and play with your new database!
   - Create new `Sequel` based model classes in `models/`, with appropriate associations
   - Be careful to follow the plural/singular conventions of Sequel
   - Integrate your models in your application:
     - require `config/environments.rb` in `app.rb`
     - you can create a `models/init.rb` that requires all the models, and then include this `init.rb` in your `app.rb`
-  - Run the `tux` gem from the command line and see if you can add/update/delete records across your tables
+  - Create and use a `console` task in Rakefile that launches `pry` with all your code preloaded. You can use it see if you can add/update/delete records across your tables
+  - You an use the `Hirb` gem to see tabular views of your records within `rake console`

 3. Update your routes and test them!
-  - Update all your routes from last week and add new ones where necessary
-    - add more GET routes to get indexes and individual resources
-    - add POST routes to create each resource in your database
   - Try to write tests for each route *before* you write the code for that route
     - Test the root route of your Web API to make sure it returns a valid message
     - Test each GET and POST route you create
       - Add a `before` block to your tests that deletes your tables before each test!
       - Write a 'happy' path that tests a successful case for each route
       - Write *at least one* 'sad' path that tests a fail case for each route
+  - Update your old routes from last week and add new ones where necessary
+    - add more GET routes to get indexes and individual resources
+    - add POST routes to create each resource in your database
 4. What are some new security risks we might have introduced this week?
   - Update your Github issues for these vulnerabilities that you can think of
   - Have we resolved any issues from last week? Let us know by closing any previous issues!
