The `add_docs` tool scans the PR code changes, and automatically suggests documentation for any code components that changed in the PR.

The `add_docs` tool supports the programming languages: Python, Java, C++, JavaScript, TypeScript, C#.

## How to use the `add_docs` tool

**Manual usage**

Comment on the PR:

```bash theme={null}
/add_docs
```

You can also state a name of a specific component in the PR to get documentation only for that component:

```bash theme={null}
/add_docs component_name
```

This tool can also be triggered interactively by using the [`analyze`](/v1/tools/tools-list/analyze) tool.

## Configuration options

Configure the `add_docs` tool by setting configurations under the `pr_add_docs` part in your [configuration file](/v1/configuration/configuration-file/).
