-Terraform ACME Provider
-========================
+This is a fork of vancluever's acme provider that also supports HTTP01 challenge.
 
-This is the repository for the Terraform ACME Provider, which one can use with
-Terraform to manage and generate certificates generated by an [ACME][about-acme]
-CA, such as [Let's Encrypt][lets-encrypt].
+Please use the original provider that only supports DNS01 if possible, as this version is not actively developed.
