# Bundling rules

How to bundle Snyk IaC custom rules

When you are ready, you can **build a custom rules bundle** by running the following command:

```
snyk-iac-rules build
```

If you have more than your generated rules in the current folder, consider using the `--ignore` option to exclude the folders and files irrelevant to a production-ready bundle. This can both speed up the process and ensure the size of the generated bundle stays small.

You can override the default entry point. If you have chosen to name the rule that evaluates something different from **`deny`**, for example, `allow`,`violation`and so on, you can override it by running:

```
snyk-iac-rules build --entrypoint "<package name>/<function name>"
```

Finally, you can check the contents of the bundle without extracting it by running:

```
tar -tf bundle.tar.gz
```

The output will be all the files included in the bundle:

```
/data.json
/lib/main.rego
/rules/MY_RULE/main.rego
/policy.wasm
/.manifest
```

You can now [run snyk iac test with your newly built custom bundle.](/scan-fix-and-prevent/scan-with-snyk/snyk-iac/current-iac-custom-rules/use-iac-custom-rules-with-cli.md)

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.snyk.io/scan-fix-and-prevent/scan-with-snyk/snyk-iac/current-iac-custom-rules/writing-rules-using-the-sdk/bundling-rules.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
