 A [Concourse](http://concourse.ci/) [resource](http://concourse.ci/resources.html) to interact with the [GitHub Status](https://developer.github.com/v3/repos/statuses/) type.
 
-
 ## Configuration
 
  * **`repository`** - the owner and repository name, slash delimited (e.g. `dpb587/github-status-resource`)
  * **`access_token`** - GitHub API access token from a user with write access to the repository (minimum token scope of `repo:status`)
  * `branch` - the branch currently being monitored (default: `master`)
+ * `base_context` - prefix for the context label (default: `concourse-ci`)
  * `context` - a label to differentiate this status from the status of other systems (default: `default`)
  * `endpoint` - GitHub API endpoint (default: `https://api.github.com`)
  * `skip_ssl_verification` - Disable certificate validation for GitHub API calls (default: `false`)
 
-
 ## Behavior
 
-
 ### `check`
 
 Triggers when the status of the branch for the configured context has been updated.
 
-
 ### `in`
 
 Lookup the state of a status.

  * `description` - a short description of the status
  * `description_path` - path to an input file whose data is the value of `description`

-
+ * `context` - overrides the source context value (default: `""`)
 
 ## Example
 
 A typical use case is to update the status of a commit as it traverses your pipeline. The following example marks the commit as pending before unit tests start. Once unit tests finish, the status is updated to either success or failure depending on how the task completes.

+```
 
 When testing pull requests, use the PR ref as the `branch`. For example, if testing PR #12345 to your repository, your resource might look like...
 
-    name: "pr-status"
-    type: "github-status"
-    source:
-      repository: {{repo_github_path}}
-      access_token: {{repo_github_token}}
-      branch: "pull/12345/head"           # +
+```yaml
+name: "pr-status"
+type: "github-status"
+source:
+  repository: {{repo_github_path}}
+  access_token: {{repo_github_token}}
+  branch: "pull/12345/head"           # +
+```

 ## Installation
 
-This resource is not included with the standard Concourse release. Use one of the following methods to make this resource available to your pipelines.
-
-
-### Deployment-wide
-
-To install on all Concourse workers, update your deployment manifest properties to include a new `groundcrew.resource_types` entry...
-
-    properties:
-      groundcrew:
-        additional_resource_types:
-          - image: "docker:///dpb587/github-status-resource#master" # +
-            type: "github-status"                                   # +
-
-
-### Pipeline-specific
-
-To use on a single pipeline, update your pipeline to include a new `resource_types` entry...
-
-    resource_types:
-      - name: "github-status"                         # +
-        type: "docker-image"                          # +

-          tag: "master"                               # +
+This resource is not included with the standard Concourse release. Add it to your pipeline's `resource_types` definition.
 
+```yaml
