+# @volar/source-map
+
+Provides functionality related to source maps.
+
+## API
+
+### This package exports a `SourceMap` class with the following methods:
+
+Params:
+
+- `fallbackToAnyMatch`(default: false): allow the start and end offsets to come from different mappings.
+- `filter?: (data: Data) => boolean)`(default: undefined):  according to mapping: Mapping<MyDataType>.data, filter out offsets that do not meet the custom conditions.
+
+Methods:
+
+- `toSourceRange(generatedStart: number, generatedEnd: number, fallbackToAnyMatch: boolean, filter?: (data: Data) => boolean)`: Returns all source start and end offsets for the given generated start and end offsets.
+
+- `toGeneratedRange(sourceStart: number, sourceEnd: number, fallbackToAnyMatch: boolean, filter?: (data: Data) => boolean) `: Returns all generated start and end offsets for the given source start and end offsets.
+
+- `toSourceLocation(generatedOffset: number, filter?: (data: Data) => boolean)`: Returns all source offsets for a given generated offset.
+
+- `toGeneratedLocation(sourceOffset: number, filter?: (data: Data) => boolean)`: Returns all generated offsets for a given source offset.
+
+## Data Structures
+
+### `Mapping`
+
+The `Mapping` is a tuple that represents a mapping in the source map. It consists of the following elements:
+
+- `source`: A string representing the source file. This can be `undefined`.
+- `sourceOffsets`: Offsets in the source code.
+- `generatedOffsets`: Offsets in the generated code.
+- `data`: The data associated with this mapping. The type of this data is generic and can be specified when creating a `SourceMap` instance.
+
+Here is an example of a `Mapping`:
+
+```ts
+let mapping: Mapping<MyDataType> = {
+    source: '.../sourceFile.ts',
+    sourceOffsets: [10],
+    generatedOffsets: [30],
+	lengths: [10],
+    data: myData,
+};
+```
+
+In this example, `myData` is of type `MyDataType`, which is the type specified for the SourceMap instance.
+
+Remember to replace `MyDataType` and `myData` with actual types and data that are relevant to your project.
