-## 5. Importer Usage
-
-The importer is a critical component for populating the API's data store. It is located at `dist/scripts/importer/run.js`.
-
-### Importer Arguments
-
-The importer accepts several command-line arguments:
-
-*   `--publish`: (Default: `false`) When present, the importer will write data directly to the API's data store. If omitted, it performs a "dry run" and writes staging output to `.local/import-output`.
-*   `--force`: Can only be used with `--publish`. Forces the importer to overwrite existing data.
-*   `--only <type>`: Imports only a specific type (e.g., `characters`, `weapons`).
-*   `--onlyWeapons`: Shorthand to import only weapons.
-*   `--skipCharacters`: Skips importing characters.
-*   `--skipWeapons`: Skips importing weapons.
-*   `--delayMs <milliseconds>`: (Default: `250`) Delay between requests to external sources.
-*   `--concurrency <number>`: (Default: `2`) Number of concurrent requests.
-
-**Example Dry Run:**
-```bash
-node dist/scripts/importer/run.js --only characters
-```
-
-**Example Publish Run:**
-```bash
-node dist/scripts/importer/run.js --publish --force --skipWeapons
-```
-
-### Important Notes on Importer
-
-*   **`--help` Warning:** The importer's CLI does not correctly process `--help` and will throw an "Unknown flag: --help" error.
-*   **`mappings.json`:** This file, located at `scripts/importer/mappings.json`, is crucial for the importer's operation. Do not move or modify it unless you understand the implications.
-*   **Dist-Only Importer:** The importer should only be run from its compiled JavaScript output in the `dist/` directory.
