 # Terraform Core Codebase Documentation

 This directory contains some documentation about the Terraform Core codebase,
 aimed at readers who are interested in making code contributions.

 If you're looking for information on _using_ Terraform, please instead refer
 to [the main Terraform CLI documentation](https://www.terraform.io/docs/cli/index.html).

 ## Terraform Core Architecture Documents

 * [Terraform Core Architecture Summary](./architecture.md): an overview of the
   main components of Terraform Core and how they interact. This is the best
   starting point if you are diving in to this codebase for the first time.

 * [Resource Instance Change Lifecycle](./resource-instance-change-lifecycle.md):
   a description of the steps in validating, planning, and applying a change
   to a resource instance, from the perspective of the provider plugin RPC
   operations. This may be useful for understanding the various expectations
   Terraform enforces about provider behavior, either if you intend to make
   changes to those behaviors or if you are implementing a new Terraform plugin
   SDK and so wish to conform to them.

   (If you are planning to write a new provider using the _official_ SDK then
   please refer to [the Extend documentation](https://www.terraform.io/docs/extend/index.html)
   instead; it presents similar information from the perspective of the SDK
   API, rather than the plugin wire protocol.)

 * [Plugin Protocol](./plugin-protocol/): gRPC/protobuf definitions for the
   plugin wire protocol and information about its versioning strategy.

   This documentation is for SDK developers, and is not necessary reading for
   those implementing a provider using the official SDK.

 * [How Terraform Uses Unicode](./unicode.md): an overview of the various
   features of Terraform that rely on Unicode and how to change those features
   to adopt new versions of Unicode.

 ## Contribution Guides

 * [Contributing to Terraform](.github/CONTRIBUTING.md): a complete guideline for those who want to contribute to this project.
