 ## Usage
 
-Add `"simple-import-sort"` to `"plugins"` in your .eslintrc:
-
-```json
-{
-  "plugins": ["simple-import-sort"]
-}
-```
-
-Then add the rules for sorting imports and exports:
-
-```json
-{
-  "rules": {
-    "simple-import-sort/imports": "error",
-    "simple-import-sort/exports": "error"
+- [eslintrc]: Add `"simple-import-sort"` to the "plugins" array in your `.eslintrc.*` file, and add the rules for sorting imports and exports. By default ESLint doesn’t parse `import` syntax – the "parserOptions" is an example of how to enable that.
