 Add the `TXT` records first, then add the `CNAME` once the verification records validate. See [Custom domain](/customize/custom-domain) for full DNS setup instructions, apex domain requirements, and TLS provisioning details.
 
 If the command fails with `Domain is already in use by another deployment in your organization` or `Domain is already claimed by another organization`, the domain is bound to another Mintlify project. See [Add domain fails with "Domain is already claimed by another organization"](/help-center/domain-already-claimed-by-another-organization) to release it and re-add it.
 
 <Note>
   If some `TXT` records are still generating when the command exits, check the [Custom domain setup](https://app.mintlify.com/settings/project/custom-domain) page in your dashboard for the remaining values.

 Display top-line KPIs for a date range: views, visitors, searches, feedback, and assistant usage. The output reports human and agent traffic separately.

 The command scans `.mdx` and `.md` files for links and excludes files matching [.mintignore](/organize/mintignore) patterns. Links inside OpenAPI specification files (`.yaml`, `.yml`, `.json`) are not checked. Links that point to ignored files report as broken.
 
 Relative links (`./`, `../`) and anchor links (`#`) inside a snippet are checked against each page that renders the snippet. The command reports one of these links only if it is broken on at least one of those pages. With `--check-anchors`, headings inside a snippet count as anchors on the pages that render it.

 mint format
 ```
 
 Run the command from the root of your docs project. It walks every subdirectory, skipping paths matched by `.gitignore` and any Mintlify ignore rules. Files that already match the canonical output are left untouched.
 
 <Tip>
   Running `mint format` can result in many changes depending on the size of your project. To avoid merge conflicts and introducing changes to other in progress work, first resolve all important pending branches. Then create a new branch for formatting changes and run `mint format` on that branch.
 </Tip>
 
 When it finishes, the command prints how many MDX files were reformatted and how many failed to parse. If any file fails, the command exits with code `1` and prints the file path and error, so you can run it in CI to enforce consistent formatting. See [Install in CI](/cli/install#install-in-ci) for an example pipeline.

 ## Telemetry
 
 The CLI collects usage telemetry to help improve Mintlify. Telemetry data includes the command name, CLI version, operating system, architecture, and Node.js version. It also records whether the CLI runs in a CI environment, whether it runs in an interactive terminal, whether this is the first time the CLI has run on your machine, and whether you are signed in. If the CLI detects an AI coding agent running it, telemetry also includes the agent's name. If you are signed in, telemetry events also include your account email address. Signed-out usage stays anonymous, and signing out removes your stored email. Mintlify does **not** collect project content or file paths.
 
 By default, the CLI collects telemetry data. You can opt out at any time using the `--telemetry` flag:

 ## Skip OpenAPI processing
 
 If you have many OpenAPI files, skip OpenAPI processing during local development to improve performance with the `--disable-openapi` flag:
