Documentation and Self-Service Workflows
Make Terraform projects approachable for the whole team with generated docs, README conventions, and pre-commit automation that keeps quality high.
Documentation and Self-Service Workflows is a free DevOps Bootcamp lesson on CoddyKit — lesson 4 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the DevOps Bootcamp learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
Why Documentation Matters
Great collaboration depends on more than tidy code. Teammates need to understand what a module does, what inputs it expects, and how to run it safely. Living documentation turns a repo into a self-service tool.
The README as the Front Door
Every Terraform repo should open with a README covering purpose, prerequisites, usage example, and inputs/outputs. It is the first thing a new contributor reads.
Generating Docs Automatically
The terraform-docs tool scans your variables and outputs and produces a Markdown table, so docs never drift from code.

Use marker comments so terraform-docs updates only a section, preserving your hand-written intro.
<!-- BEGIN_TF_DOCS -->
<!-- END_TF_DOCS -->Descriptions Drive Quality Docs
Generated docs are only as good as your description fields. Treat them as user-facing copy.

type = string
description = "EC2 size, e.g. t3.micro for dev or m5.large for prod"
default = "t3.micro"
}Pre-commit Hooks
A pre-commit framework runs checks before every commit, catching issues before they reach review. It is configured with a YAML file.
repos:
- repo: https://github.com/antonbabenko/pre-commit-terraform
hooks:
- id: terraform_fmt
- id: terraform_validate
- id: terraform_docsInstalling the Hooks
Run the install command once per clone so the hooks fire automatically on commit.

Pair terraform fmt with a linter like tflint to catch provider-specific mistakes such as invalid instance types.

Document your team's workflow in a CONTRIBUTING file: branch naming, how to run plan, who approves applies. This removes guesswork for newcomers.
Architecture Decision Records
ADRs capture why a choice was made (for example, why you chose a remote backend). Storing them in the repo preserves context long after the original author leaves.

An examples/ folder with runnable mini-configs lets users copy a working setup instead of reverse-engineering inputs. It also doubles as integration test material.

Recap: Self-Service Repos
You learned to make collaboration frictionless:
- A strong README and CONTRIBUTING guide.
- terraform-docs for auto-generated input/output tables.
- pre-commit hooks running fmt, validate, and lint.
- ADRs and examples that capture context and usage.
