+## Sourcemapped test fixtures
+
+The test fixtures in this folder are used to generate a suite of tests for sourcemapped
+files that have been passed through various tools like Babel and Typescript, and various
+bundlers like Rollup and Webpack.
+
+The fixtures follow a naming scheme where:
+
+* `babel-` means the file requires Babel in order to be consumed by a bundler.
+* `typescript-` means the file requires Typescript in order to be consumed by a bundler.
+* `-cjs` means the file is either:
+  * Written in CommonJS
+  * May be converted to CommonJS when Babel is enabled
+
+  This is used to exclude these files from processing by bundlers that expect input
+  files to be ES modules.
