 # Angular Language Service Test
 
 This directory is an integration test for `@angular/language-service` to ensure
-that various versions of the server can be loaded in the supported versions of 
-TypeScript's language service.
+that the language service works correctly as a `tsserver` plugin.
 
-## New supported version of TypeScript

-To add a new supported version of TypeScript:
-
-1) Create directory in `typescripts` to hold the new version following the pattern
-   of the other versions.
-2) Add the directory name to the end of the `TYPESCRIPTS` variable in the 
-   `scripts/env.sh` file.
-3) Run `scripts/update_golden.sh` to generate the expected files.
-4) Verify the expected output is reasonable by comparing to a known good output
-   from a previous version.
+- Use `yarn install` to install all dependencies in this directory and in the Angular repo root
+    directory.
+- From the Angular repo root directory, build Angular in the `dist/packages-dist` folder with
+    `./scripts/build-packages-dist.sh`.
+- In this directory, run the tests with `yarn test`.
 
 ## Update golden files
 
-If the expected output needs to be updated run `scripts/update_golden.sh` to

+If the expected output needs to be updated, run `yarn golden my-golden.json`, replacing
+`my-golden.json` with the golden file to be updated. Do not qualify the file with a directory path.
+See [generate.ts](./generate.ts) for more information.
