Martin Atkins 1f241f8f83 docs: Some updates to the architecture summary This doc was originally written in the middle of Terraform v0.12 development while some refactoring was already in progress. Here we update those parts to refer to where the relevant functionality finally landed, and also update some things that we did not anticipate changing at the time but ended up having to be changed during the v0.12 development anyway.		2019-03-25 08:01:44 -07:00

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.

Terraform Core Architecture Documents

Terraform Core Architecture Summary: 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: 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 instead; it presents similar information from the perspective of the SDK API, rather than the plugin wire protocol.)

Maintainer Etiquette: guidelines and expectations for those who serve as Pull Request reviewers, issue triagers, etc.
