+
+[![npm package][npm-badge]][npm-link] [![license MIT][license-badge]][license-link] [![ivuorinen's Code Style][style-badge]][style-link]
+
+Check for existence of common configuration files in usually used locations.
+
+## Installation
+
+Install `this package` as a _`dependency`_:
+
+```sh
+# npm
+npm install @ivuorinen/config-checker --save
+
+# Yarn
+yarn add @ivuorinen/config-checker
+```
+
+## Usage
+
+This package is intended to be used in lifecycle events of other packages.
+
+Configuration packages located in this repository use this tool to check for existence of configuration files, and if they exist, they will not create new ones.
+
+### Real world example
+
+For commitlint-config you can find the usage in the [commitlint-config postinstall.cjs][commitlint-postinstall-link] file.
+
+Here's a snippet from the file:
+
+```js
+const process = require("process");
+const checkConfig = require("@ivuorinen/config-checker");
+const foundConfig = checkConfig("commitlint");
+
+if (foundConfig.length > 0) {
+  console.log("commitlint-config: Found existing commitlint config file, skipping creation.");
+  console.log(
+    "commitlint-config: If you want to create a new config file, please remove the existing one.",
+  );
+  console.log(`commitlint-config: Found config files at: ${foundConfig.join(", ")}`);
+  process.exit(0);
+}
+```
+
