+  version: 3,
+  names: ['foo'],
+  sources: ['input.js'],
+  mappings: 'AAAAA',
+});
+```
+
+#### SourceMapConsumer.prototype.originalPositionFor(generatedPosition)
+
+```typescript
+const smc = new SourceMapConsumer(map);
+smc.originalPositionFor({ line: 1, column: 0 });
+```
+
+### SourceMapGenerator
+
+```typescript
+import { SourceMapGenerator } from '@jridgewell/source-map';
+const smg = new SourceMapGenerator({
+  file: 'output.js',
+  sourceRoot: 'https://example.com/',
+});
+```
+
+#### SourceMapGenerator.prototype.addMapping(mapping)
+
+```typescript
+const smg = new SourceMapGenerator();
+smg.addMapping({
+  generated: { line: 1, column: 0 },
+  source: 'input.js',
+  original: { line: 1, column: 0 },
+  name: 'foo',
+});
+```
+
+#### SourceMapGenerator.prototype.setSourceContent(sourceFile, sourceContent)
+
+```typescript
+const smg = new SourceMapGenerator();
+smg.setSourceContent('input.js', 'foobar');
+```
+
+#### SourceMapGenerator.prototype.toJSON()
+
+```typescript
+const smg = new SourceMapGenerator();
+smg.toJSON(); // { version: 3, names: [], sources: [], mappings: '' }
+```
+
+#### SourceMapGenerator.prototype.toDecodedMap()
