+# Running Examples
 
+The quickest way to start experimenting with dex is to run a single dex-worker locally, with an in-process database, and then interact with it using the example programs in this directory.
 
 ## Build Everything and Start dex-worker
 
-This section is required for both the Example App and the Example CLI. 
+First, build the example webapp client and example CLI client.
 
-1. Build everything:
-   ```
-   ./build
-   ```
+```
+./build
+```
 
-1. Copy the various example configurations.
-    ```
-    cp static/fixtures/connectors.json.sample static/fixtures/connectors.json
-    cp static/fixtures/users.json.sample static/fixtures/users.json
-    cp static/fixtures/emailer.json.sample static/fixtures/emailer.json
-    ```
+Now copy the example configurations into place to get dex configured.
+You can customize these later but the defaults should work fine.
 
-1. Run dex_worker in local mode.
-    ```
-    ./bin/dex-worker --no-db &
-    ```
+```
+cp static/fixtures/connectors.json.sample static/fixtures/connectors.json
+cp static/fixtures/users.json.sample static/fixtures/users.json
+cp static/fixtures/emailer.json.sample static/fixtures/emailer.json
+```
 
+With `dex-worker` configuration in place we can start dex in local mode.
 
-## Example App
+```
+./bin/dex-worker --no-db &
+```
 
-1. Build and run example app webserver, pointing the discovery URL to local Dex, and 
+## Example Webapp Client
+
+Build and run the example app webserver by pointing the discovery URL to local Dex, and 
 supplying the client information from `./static/fixtures/clients.json` into the flags.
-   ```
-   ./bin/example-app --client-id=XXX --client-secret=secrete --discovery=http://127.0.0.1:5556 &
-   ```
 
-1. Navigate browser to `http://localhost:5555` and click "login" link
-1. Click "Login with Local"
-1. Enter in sample credentials from `static/fixtures/connectors.json`:
-   ```
-   email: elroy77@example.com
-   password: bones
-   ```
-1. Observe user information in example app.
+```
+./bin/example-app \
+	--client-id=example-app \
+	--client-secret=example-app-secret \
+	--discovery=http://127.0.0.1:5556
+```
 
-## Example CLI
-*TODO*
+Visit [http://localhost:5555](http://localhost:5555) in your browser and click "login" link.
+Next click "Login with Local" and enter the sample credentials from `static/fixtures/connectors.json`:
+
+```
+email: elroy77@example.com
+password: bones
+```
+
+The example app will dump out details of the JWT issued by Dex which means that authentication was successful and the application has authenticated you as a valid user.
+You can play with adding additional users in connectors.json and users.json.
+
+## Example CLI Client
+
+The example CLI will start, connect to the Dex instance to gather discovery information, listen on `localhost:8000`, and then acquire a client credentials JWT and print it out.
+
+```
+./bin/example-cli \
+	--client-id example-cli
+	--client-secret examplie-cli-secret
+	--discovery=http://127.0.0.1:5556
+```
