-A strict eslint config for linting `js` / `ts` / `package.json` files. Based on [standard.js](https://github.com/standard/standard) without any stylistic opinions.
-
-## Feature
-
-- Lint `js` / `mjs` / `cjs` / `jsx` / `ts` / `mts` / `cts` / `tsx` / `package.json` files only.
-- One-line of config.
-- Type safe. TypeScript friendly.
-- Respect `.gitignore`.
-- Based on [standard.js](https://github.com/standard/standard).
-- Have no stylistic opinions. Prettier friendly.
-- [ESLint Flat config](https://eslint.org/docs/latest/use/configure/configuration-files-new), compose easily!
-- Strict, but progressive.
-- Modern. ESM first.
-- React friendly.
-- NestJS friendly.
-
-## Usage
-
-Install it in the root of js / ts project.
-
-```sh
-npm install -D eslint @git-validator/eslint-config
-```
-
-Config `eslint.config.js` (for ESM).
-
-```js
-import config from "@git-validator/eslint-config";
-
-export default config;
-```
-
-If you are in CommonJS, config `eslint.config.js` bellow:
-
-```js
-module.exports = import("@git-validator/eslint-config");
-```
-
-Config `package.json`
-
-```json
-{
-  "scripts": {
-    "lint": "eslint .",
-    "lint:fix": "eslint . --fix"
-  }
-}
-```
-
-> Note: TypeScript project is required a `tsconfig.json` file in the root.
-
-## Advanced Usage
-
-### Config Builder
-
-The default config is very strict. If you don't like the default config, use `Builder` to customize your own.
-
-```ts
-import { Builder } from "@git-validator/eslint-config";
-
-export default new Builder()
-  .enablePackagejson({
-    pick: ["packagejson/top-types"], // only these rules will work for package.json files
-  })
-  .enableJavascript({
-    omit: ["no-var"], // these rules will not work for js files
-  })
-  .enableTypescript({
-    project: "tsconfig.json", // tsconfig.json path
-    extend: {
-      // apply additional rules for ts files
-      "@typescript-eslint/no-explicit-any": "error",
-      "@typescript-eslint/consistent-type-assertions": [
-        "error",
-        { assertionStyle: "never" },
-      ],
-      "@typescript-eslint/no-non-null-assertion": "error",
-    },
-  })
-  .toConfig();
-```
