+# heroku\_cert
+
+Provides a Heroku SSL certificate resource. It allows to set a given certificate for a Heroku app.
+
+## Example Usage
+
+```
+# Create a new heroku app
+resource "heroku_app" "default" {
+    name = "test-app"
+}
+
+# Add-on SSL to application
+resource "heroku_addon" "ssl" {
+    app = "${heroku_app.service.name}"
+    plan = "ssl"
+}
+
+# Establish certificate for a given application
+resource "heroku_cert" "ssl_certificate" {
+    app = "${heroku_app.service.name}"
+    certificate_chain = "${file("server.crt")}"
+    private_key = "${file("server.key")}"
+    depends_on = "heroku_addon.ssl"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `app` - (Required) The Heroku app to add to.
+* `certificate_chain` - (Required) The certificate chain to add
+* `private_key` - (Required) The private key for a given certificate chain
+
+## Attributes Reference
+
+The following attributes are exported:
+
+* `id` - The ID of the add-on
+* `cname` - The CNAME of ssl endpoint
+* `name` - The name of the SSL certificate
+
