+The import attributes/assertions syntax: 
+- `with`: `import "..." with { type: "json" }`
+- `assert`: `import "..." assert { type: "json" }`
+- `with-legacy`: `import "..." with type: "json"`.

 ### How does import sort work ?
 
 The plugin extracts the imports which are defined in `importOrder`. These imports are considered as _local imports_.
