+# 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.
+
+## 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.
+
+## Update golden files
+
+If the expected output needs to be updated run `scripts/update_golden.sh` to
+update the expected output of the server.
+
+## Adding a new fixture
+
+Currently there is no automated way to produce a new fixture. The way the
+current fixtures were created was to hack a version of tsserver.js to write the
+commands from `VSCode` to a file while performing the operation to be tested.
+I also hand modified the input to remove superfluous request.
+
+Once a new fixture is created:
+
+1) Add the fixture base name (without the .json) to `FIXTURES` in 
+   `scripts/env.sh`.
+2) Run `scripts/udpate_golden.sh` to produce the expected output files.
+3) Hand validate the expected output is reasonable.
