 Create or modify a `konsistent.json` file that enforces structural conventions for the project. The `konsistent` CLI checks filesystem structure and TypeScript exports/imports — it is not a style linter.
 
+## Prerequisites
+
+Check if the `konsistent` package is already installed:
+
+- `konsistent` available in root `package.json`
+- `node_modules/konsistent` directory exists
+- a `konsistent` script exists in `package.json`
+
+If not, the `konsistent` CLI must be installed first. Use the project's package manager. For example, with PNPM:
+
+```bash
+pnpm add konsistent --save-dev
+```
+
+Then, ensure `package.json` has a `konsistent` script which invokes the `konsistent` CLI. At a minimum:
+
+```
+  "scripts": {
+    "konsistent": "konsistent"
+  }
+```
+
+Once the package has been successfully installed, proceed to the primary workflow.

 **Important reminder:** The objective is NOT to write a `konsistent.json` file that leads to zero errors when running the CLI. That would defeat the purpose. The objective is to create a konsistent.json file that identifies violations to patterns used in the codebase, even if they are not being 100% adhered to.
