+This plugin provides a way to send HTTP requests as a workflow step or
+node step in a [Rundeck](https://rundeck.org) job.
+
+This plugin is bundled with the Rundeck application, so no separate
+installation is required. It is built and maintained as part of the
+[rundeck/rundeck](https://github.com/rundeck/rundeck) project.
 
 ## Features
 
-- GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS
-- Authentication: BASIC or OAuth 2.0
+- HTTP methods: GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS
+- Authentication: Basic, Bearer Token, or OAuth 2.0 (Client Credentials Grant)
 - Project or Framework level configuration
-- Support for Self Signed SSL Certificates
+- Support for self-signed SSL certificates
+
+## Usage
+
+Add "HTTP Workflow Step" or "HTTP Node Step" to a job as a workflow step
+or node step, and configure the URL, method, headers, body, and
+authentication as needed.
+
+See the [HTTP Request Workflow Step documentation](https://docs.rundeck.com/docs/manual/jobs/job-plugins/workflow-steps/http-request.html)
+for full reference on this plugin's options.
 
 ## Caveats
 
 OAuth 2.0 only supports the Client Credentials Grant Type. The OAuth
 configuration is per-project or per-framework. This means that each job
-will share the entire project or entire frameworks credentials. However,
-this allows those credentials to be externalized into the framework
-configuration and avoids them being exported with projects.
-
-## Todo
-
-- Support request parameters from config and/or data
+will share the entire project's or entire framework's credentials.
+However, this allows those credentials to be externalized into the
+framework configuration and avoids them being exported with projects.
