+# SkyWalking Terraform and Ansible
+
+This repository contains the Terraform scripts to create the infrastructure for SkyWalking on cloud vendors,
+and the Ansible playbooks to install SkyWalking on the created infrastructure, or on the existing infrastructure,
+no matter on-premises or on cloud vendors, such as AWS.
+
+# Terraform
+
+For now, we have supported the following cloud vendors, and we welcome everyone to contribute supports for
+more cloud vendors:
+
+- Amazon Web Services (AWS): go to the [aws](aws) folder for more details.
+
+# Ansible
+
+You can use the Ansible playbook in combination with the Terraform to create necessary infrastructure and install
+SkyWalking on the created infrastructure, or you can use the Ansible to install SkyWalking on the existing infrastructure.
+The Ansible playbook and documentation about how to use it can be found in the [ansible](ansible) folder.
