+
+# heroku\_pipeline
+
+
+Provides a [Heroku Pipeline](https://devcenter.heroku.com/articles/pipelines)
+resource.
+
+A pipeline is a group of Heroku apps that share the same codebase. Once a
+pipeline is created, and apps are added to different stages using
+[`heroku_pipeline_coupling`](./pipeline_coupling.html), you can promote app
+slugs to the next stage.
+
+## Example Usage
+
+```hcl
+# Create Heroku apps for staging and production
+resource "heroku_app" "staging" {
+  name = "test-app-staging"
+}
+
+resource "heroku_app" "production" {
+  name = "test-app-production"
+}
+
+# Create a Heroku pipeline
+resource "heroku_pipeline" "test-app" {
+  name = "test-app"
+}
+
+# Couple apps to different pipeline stages
+resource "heroku_pipeline_coupling" "staging" {
+  app      = "${heroku_app.staging.name}"
+  pipeline = "${heroku_pipeline.test-app.id}"
+  stage    = "staging"
+}
+
+resource "heroku_pipeline_coupling" "production" {
+  app      = "${heroku_app.production.name}"
+  pipeline = "${heroku_pipeline.test-app.id}"
+  stage    = "production"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `name` - (Required) The name of the pipeline.
+
+## Attributes Reference
+
+The following attributes are exported:
+
+* `id` - The UUID of the pipeline.
+* `name` - The name of the pipeline.

+  pipeline = "${heroku_pipeline.test-app.id}"
+  stage    = "production"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `app` - (Required) The name of the app for this coupling.
+* `pipeline` - (Required) The ID of the pipeline to add this app to.
+* `stage` - (Required) The stage to couple this app to. Must be one of
+`review`, `development`, `staging`, or `production`.
+
+## Attributes Reference
+
+The following attributes are exported:
+
+* `id` - The UUID of this pipeline coupling.
+* `app` - The name of the application.
+* `pipeline` - The UUID of the pipeline.
+* `stage` - The stage for this coupling.
