 ## Running the Tests
 To run all tests, invoke the runtests target using jake:

-`jake runtests tests=<regex>`
+```Shell

-`jake runtests tests=compiler`
+```Shell
+jake runtests tests=compiler

+These files support metadata tags in the format  `// @metaDataName: value`. The supported names and values are:
 
-* comments, sourcemap, noimplicitany, declaration: true or false (corresponds to the compiler command-line options of the same name)
-* target: ES3 or ES5 (same as compiler)
-* out, outDir: path (same as compiler)
-* module: local, commonjs, or amd (local corresponds to not passing any compiler --module flag)

+* `module`: local, commonjs, or amd (local corresponds to not passing any compiler --module flag)
+* `fileName`: path

+**Note** that if you have a test corresponding to a specific spec compliance item, you can place it in `tests\cases\conformance` in an appropriately-named subfolder. 
 **Note** that filenames here must be distinct from all other compiler testcase names, so you may have to work a bit to find a unique name if it's something common.
 
+### Tests for multiple files
+
+When one needs to test for scenarios which require multiple files, it is useful to use the `fileName` metadata tag as such:
+
+```TypeScript
+// @fileName: file1.ts
+export function f() {
+}
+
+// @fileName: file2.ts
+import { f as g } from "file1";
+
+var x = g();
+```
+
+One can also write a project test, but it is slightly more involved.
+
 ## Managing the Baselines
-Compiler testcases generate baselines that track the emitted .js, the errors produced by the compiler, and the type of each expression in the file. Additionally, some testcases opt in to baselining the source map output.

 When a change in the baselines is detected, the test will fail. To inspect changes vs the expected baselines, use
 
-`jake diff`
+```Shell
+jake diff
+```
 
 After verifying that the changes in the baselines are correct, run
 
-`jake baseline-accept`
+```Shell
+jake baseline-accept
+```
 
-to establish the new baselines as the desired behavior. This will change the files in tests\baselines\reference, which should be included as part of your commit. It's important to carefully validate changes in the baselines.

 **Note** that baseline-accept should only be run after a full test run! Accepting baselines after running a subset of tests will delete baseline files for the tests that didn't run.

 [TypeScript](http://www.typescriptlang.org/) is a language for application-scale JavaScript. TypeScript adds optional types, classes, and modules to JavaScript. TypeScript supports tools for large-scale JavaScript applications for any browser, for any host, on any OS. TypeScript compiles to readable, standards-based JavaScript. Try it out at the [playground](http://www.typescriptlang.org/Playground), and stay up to date via [our blog](http://blogs.msdn.com/typescript) and [twitter account](https://twitter.com/typescriptlang).

 ## Building
 
-In order to build the TypeScript compiler, ensure that you have [Git](http://git-scm.com/downloads) and [Node.js](http://nodejs.org/) installed. Note that you need to have autocrlf off as we track whitespace changes (`git config --global core.autocrlf false`).
