 Here's one way to get setup:
 	rackup

 2. **Configure your exercism CLI to point to that x-api.** Out of the box, the CLI is configured to point to the production instances of the API (for account-specific data) and X-API (for problem data).  You need to configure your CLI to point to the X-API instance you stood up in the prior step.

-	If you haven't already, you'll need need to [install the CLI](http://help.exercism.io/installing-the-cli.html).

 	If things are properly setup:
 	* `exercism debug` output will include "`XAPI: http://localhost:9292 [connected]`"
 	* `tree java` will look something like this:
-

 		```
 		java
 		└── bob
 	git clone git@github.com:jtigger/xjava.git
 	git remote add upstream https://github.com/exercism/xjava.git
 	git pull --rebase upstream/master
-	cd ~/workspace/exercism/x-api/problems
+	cd ~/workspace/exercism/x-api/tracks
 	rm -rf java
 	ln -s ../../xjava java

 and if you review the logs of your x-api, you'll find:
 Before you submit a pull request, please ensure:
 
 - the test suite covers the essential parts of the problem and interesting corner cases.
-- your example solution represents your best attempt at exemplary code. 
 - the build script (`./bin/build.sh`) compiles and tests your code successfully.
 
 
 *(These instructions assume you setup your development environment using the instructions above.)*
 
 1. **Run the build script, locally.**
- 
+
    ```
    cd ~/workspace/exercism/xjava
    ./bin/build.sh
    ```
 
    verify that the script runs successfully.
-   
+
 2. **Fetch the problem from your local x-api, using the CLI.**
 
    ```
    cd ~/workspace/exercism/exercises
    exercism fetch java <problem-slug>
    ```
-   
+
    verify that the fetched problem does *not* contain any files not needed for the problem.
-   
+
 3. **Run the tests against the example source.**
 
    ```
    ```
 
    verify that all tests pass.
