 1. Wharfie creates a new docker container from the source image, mounting the volumes from the

 1. Wharfie bind-mounts the application source into `/usr/source` in the container

 1. Wharfie commits the container as a new image, setting the new image's command to `/usr/bin/run`

-
-1. `save-artifact`: This script is responsible for moving build dependencies to `/usr/artifacts`
-1. `restore-artifact`: This script is responsible for restoring a build environment from

 ### Getting started
 
+You can start using wharfie right away by using the sample image and application sources in the
+`test_sources` directory.  Here's an example that builds a simple HTML app:
+
+	docker build -rm -t fedora-mock test_sources/images/fedora-mock
+	wharfie build fedora-mock test_sources/applications/html --tag wharfie_app
+	docker run -rm -i -p -t wharfie_app
+
+### Validating a source image
+
+    wharfie validate IMAGE_NAME [--supports-incremental] [--url=URL] [--timeout=TIMEOUT] [-l LOG_LEVEL]
+
+    Arguments:
+        IMAGE_NAME      Source image name. Wharfie will pull this image if not available locally.
+
+    Options:
+        --supports-incremental          Check for compatibility with incremental builds
+        -l LOG_LEVEL                    Logging level. Default: INFO
+        --timeout=TIMEOUT               Timeout commands if they take too long. Default: 120 seconds.
+        --user=USERID                   Perform the build as specified user.
+        --url=URL                       Connect to docker at the specified url [default: unix://var/run/docker.sock]
+
+You can validate that an image is usable as a wharfie source image as follows:
+
+	wharfie validate IMAGE_NAME
+
+Add the `--supports-incremental` option to validate the a source image supports incremental builds:
+
+	wharfie validate IMAGE_NAME --supports-incremental
+
+### Building a deployable image with wharfie
+
+    wharfie build IMAGE_NAME SOURCE_DIR [--tag=BUILD_TAG] [--incremental=PREV_BUILD]
+    	[--user=USERID] [--url=URL] [--timeout=TIMEOUT] [-e ENV_NAME=VALUE]... [-l LOG_LEVEL]
+
+    Arguments:
+        IMAGE_NAME      Source image name. Wharfie will pull this image if not available locally.
+        SOURCE_DIR      Directory containing your application sources.
+
+    Options:
+        --incremental=PREV_BUILD        Perform an incremental build. PREV_BUILD specified the previous built image.
+        -l LOG_LEVEL                    Logging level. Default: INFO
+        --tag=BUILD_TAG                 Tag a successful build with the provided name.
+        --timeout=TIMEOUT               Timeout commands if they take too long. Default: 120 seconds.
+        --user=USERID                   Perform the build as specified user.
+        --url=URL                       Connect to docker at the specified url [default: unix://var/run/docker.sock]
