+## Add new hook
+
+You can use [this PR](https://github.com/antonbabenko/pre-commit-terraform/pull/252) as an example.
+
+### Before write code
+
+1. Try to figure out future hook usage.
+2. Confirm the concept with [Anton Babenko](https://github.com/antonbabenko).
+
+### Prepare basic documentation
+
+1. Identify and describe dependencies in [Install dependencies](../README.md#1-install-dependencies) and [Available Hooks](../README.md#available-hooks) sections
+
+### Add code
+
+1. Based on prev. block, add hook dependencies installation to [Dockerfile](../Dockerfile).
+ Check that works:
+ * `docker build -t pre-commit --build-arg INSTALL_ALL=true .`
+ * `docker build -t pre-commit --build-arg _VERSION=latest .`
+ * `docker build -t pre-commit --build-arg _VERSION=<1.2.3> .`
+2. Add new hook to [`.pre-commit-hooks.yaml`](../.pre-commit-hooks.yaml)
+3. Create hook file. Don't forget to make it executable via `chmod +x /path/to/hook/file`.
+4. Test hook. How to do it is described in [Run and debug hooks locally](#run-and-debug-hooks-locally) section.
+5. Test hook one more time.
+ 1. Push commit with hook file to GitHub
+ 2. Grab SHA hash of the commit
+ 3. Test hook using `.pre-commit-config.yaml`:
+
+ ```yaml
+ repos:
+ - repo: https://github.com/antonbabenko/pre-commit-terraform # Your repo

+ hooks:
+ - id: terraform_docs # New hook name
+ args:
+ - --args=--config=.terraform-docs.yml # Some args that you'd like to test
+ ```
+
+### Finish with the documentation
+
+1. Add hook description to [Available Hooks](../README.md#available-hooks).
+2. Create and populate a new hook section in [Hooks usage notes and examples](../README.md#hooks-usage-notes-and-examples).

+### infracost_breakdown
+
+`infracost_breakdown` build on top of the `infracost breakdown` command. It, if needed, runs `terraform init`, `terraform plan` and calls `infracost` API - so this hook can run up to several minutes.
+
+Unlike most other hooks, this one triggers all changes to the files but checks predefined paths each time.
+
+For example, the hook tracks `--path=./env/dev` and `./env/dev` depend on `./main.tf`. So when you will make changes to `./main.tf` - the hook will run and show the cost changes for `./env/dev`.
+
+
+1. `infracost_breakdown` supports custom arguments so you can pass [supported flags](https://www.infracost.io/docs/#useful-options).
+ The following example only shows costs:
+
+ ```yaml
+ - id: infracost_breakdown
+ args:
+ - --args=--path=./env/dev
+ verbose: true # Always show costs
+ ```
+
+ Output
+
+ ```bash
+ Running in "env/dev"
+
+ Summary: {
+ "unsupportedResourceCounts": {
+ "aws_sns_topic_subscription": 1
+ }
+ }
+
+ Total Monthly Cost: 86.83 USD
+ Total Monthly Cost (diff): 86.83 USD
+ ```
+
+
+
+2. You can provide limitations when the hook should fail:
+
+ ```yaml
+ - id: infracost_breakdown
+ args:
+ - --args=--path=./env/dev
+ - --hook-config=.totalHourlyCost|tonumber > 0.1
+ - --hook-config=.totalHourlyCost|tonumber > 1
+ - --hook-config=.projects[].diff.totalMonthlyCost|tonumber != 10000
+ - --hook-config=.currency == "USD"
+ ```
+
+ Output
+
+ ```bash
+ Running in "env/dev"
+ Passed: .totalHourlyCost|tonumber > 0.1 0.11894520547945205 > 0.1
+ Failed: .totalHourlyCost|tonumber > 1 0.11894520547945205 > 1
+ Passed: .projects[].diff.totalMonthlyCost|tonumber !=10000 86.83 != 10000
+ Passed: .currency == "USD" "USD" == "USD"
+
+ Summary: {
+ "unsupportedResourceCounts": {
+ "aws_sns_topic_subscription": 1
+ }
+ }
+
+ Total Monthly Cost: 86.83 USD
+ Total Monthly Cost (diff): 86.83 USD
+ ```
+
+
+
+ * Hook uses `jq` to parse `infracost` output, so paths to values like `.totalHourlyCost` and `.totalMonthlyCost` should be in jq-compatible format.
+ To check available structure use `infracost breakdown -p PATH_TO_TF_DIR --format json | jq -r . > infracost.json`. And play with it on [jqplay.org](https://jqplay.org/)
+ * Supported comparison operators: `<`, `<=`, `==`, `!=`, `>=`, `>`.
+ * Most useful paths and checks:
+ * `.totalHourlyCost` (same to `.projects[].breakdown.totalHourlyCost`) - show total hourly infra cost
+ * `.totalMonthlyCost` (same to `.projects[].breakdown.totalMonthlyCost`) - show total monthly infra cost
+ * `.projects[].diff.totalHourlyCost` - show hourly cost diff between existing infra and tf plan
+ * `.projects[].diff.totalMonthlyCost` - show monthly cost diff between existing infra and tf plan
+ * `.diffTotalHourlyCost` (for Infracost version 0.9.12 or newer) or `[.projects[].diff.totalMonthlyCost | select (.!=null) | tonumber] | add > 1000` (for Infracost older than 0.9.12):
+ * fail if changes push the total monthly cost estimate above $1K
+ * fail if changes increase the cost by $1K.
+ * You can set up only one path per one hook (`- id: infracost_breakdown`) - this is an `infracost` limitation.
+ * Set `verbose: true` to see cost even when the checks are passed.
+ * To disable hook color output, set `PRE_COMMIT_COLOR=never` env var
+
+3. **Docker usage**. In `docker build` or `docker run` command:
+ * You need to provide [Infracost API key](https://www.infracost.io/docs/integrations/environment_variables/#infracost_api_key) via `-e INFRACOST_API_KEY=`. By default it is saved in `~/.config/infracost/credentials.yml`
+ * Set `-e INFRACOST_SKIP_UPDATE_CHECK=true` to skip the Infracost update check; can be useful in CI/CD systems. [Doc](https://www.infracost.io/docs/integrations/environment_variables/#infracost_skip_update_check)
