@@ -4,16 +4,26 @@ The files in this directory are mostly from the TypeScript repository. We
 currently (unfortunately) have a rather manual process for upgrading TypeScript.
 It works like this currently:
 
-1. Checkout typescript repo in a separate directory.
-2. Copy typescript.js into Deno repo.
-3. Copy d.ts files into dts directory.
+1. Checkout denoland/TypeScript repo in a separate directory.
+1. Add Microsoft/TypeScript as a remote and fetch its latest tags
+1. Checkout a new branch based on this tag.
+1. Cherry pick the custom commit we made in a previous release to the new one.
+1. This commit has a "deno.ts" file in it. Read the instructions in it.
+1. Copy typescript.js into Deno repo.
+1. Copy d.ts files into dts directory.
 
 So that might look something like this:
 
 ```
-git clone https://github.com/microsoft/TypeScript.git
+git clone https://github.com/denoland/TypeScript.git
 cd typescript
+git remote add upstream https://github.com/Microsoft/TypeScript
+git fetch upstream
 git checkout v3.9.7
+git checkout -b branch_v3.9.7
+git cherry pick <previous-release-branch-commit-we-did>
+npm install
+gulp local
 rsync lib/typescript.js ~/src/deno/cli/tsc/00_typescript.js
 rsync --exclude=protocol.d.ts --exclude=tsserverlibrary.d.ts --exclude=typescriptServices.d.ts lib/*.d.ts ~/src/deno/cli/dts/
 ```
