-# Terraform Content Provider
+# Terraform Extensions Provider
 
-This is a plugin for HashiCorp [Terraform](https://terraform.io), which helps fetching some content from a remote URL, saving it (or another content) locally to a file, reusing variables with interpolated values.
+This is a plugin for HashiCorp [Terraform](https://terraform.io), which provides one with abilities to:

 ### Mandatory Parameters
 - `value` - variable value

-Defines a resource that is got recreated every time the value of the `trigger` field changes. This is a convenient way of calling some provisioner on every `trigger` field change.
