 ## Understanding the Docker configuration
 
-The `jobs` section in the configuration file defines a job named `server`. It's `source` property contains the information necessary to setup the Docker container. 
+The `jobs` section in the configuration file defines a job named `server`. It's `sources` property contains the information about where to download any sources necessary for the job. In this case there is a single source named `techempower` and so the source will be copied into a directory called `techempower` in the job's working directory. The `dockerFile`, `dockerImageName`, `dockerContextDirectory` are then used to define what docker command is run.
 
 In this case it is a **Netty** application taken from the [TechEmpower](https://github.com/TechEmpower/FrameworkBenchmarks) repository which contains several types of benchmarks for any language and framework. Netty is a Java web application framework.

-The `dockerFile` property is relative to the root of the repository, and point to the Docker file to build.
+The `dockerFile` property is relative to the job's working directory, and points to the Docker file to build. Note that the path starts with `techempower` because each source is copied to a directory with the name of the source.
 
 The `dockerImageName` is used on the agent to name the container. By setting it Docker will be able to reuse previous cached containers and start benchmarks faster.
 
-The `dockerContextDirectory` is a path representing the working directory inside the Docker file script. Any path using `./` in the Docker file will be this value. It's relative to the root of the source (the clone of the repository).
+The `dockerContextDirectory` is a path representing the working directory inside the Docker file script. Any path using `./` in the Docker file will be this value. It's relative to the job's working directory.
 
 The property `port` is used to let the Crank agent detect when the application is ready to accept requests. When specified, the agent will try to ping the expected endpoint until it successfully answers. Another option is to define the property `readyStateText` with some value that is written on the standard output once the application has started. In the case of a Netty application, the service emits `Httpd started. Listening on: 0.0.0.0/0.0.0.0:8080` when the service is ready. Similarly, an ASP.NET application outputs `Application started. Press Ctrl+C to shut down.`

 ## Define the scenario
 
-In the [Getting Started](getting_started.md) tutorial, the **hello** application is benchmarked. It's `source` section is pointing to the Crank repository to inform the Crank Agent to clone it and build it.
+In the [Getting Started](getting_started.md) tutorial, the **hello** application is benchmarked. It's `sources` section has a source named `crank` which is pointing to the Crank repository to inform the Crank Agent to clone it. By default, a source will be cloned to a directory with the same name as the source. 
+
+The `project` property defines a path to a .NET project file that should be built and run as the work carried out by this job. The project's path starts with `crank` because that is the folder that the source is cloned to, and `samples/hello/hello.csproj` is where the project file is located inside that source.
 
 ```yml
   server:
-    source:
-      repository: https://github.com/dotnet/crank
-      branchOrCommit: main
-      project: samples/hello/hello.csproj

     readyStateText: Application started.
 ```
 
 In cases where you want to iterate quickly on an application, it's easier to do changes locally and send the source file to the agent instead of having it clone changes what you would have to push.
 
-The `source` property of a job has a `localFolder` property that can be set to a local folder. 
+A source inside the `sources` property can specify a `localFolder` property that can be set to a local folder.
 
 The file `/crank/samples/local/local.benchmarks.yml` demonstrates how to use this property instead.
