+# Package Manager
+
+This package is a web-compatible package manager built with tsserverlib
+compatibility in mind. It does not require a "real" filesystem or a "real" NPM
+installation, but instead uses [orogene](https://github.com/orogene/orogene)
+to perform package management operations.
+
+It is largely a thin wrapper around Orogene's [node-maintainer WASM
+API](https://github.com/orogene/orogene/blob/abba96e6662c3465a498fbe6154ffcf2fe33fac4/crates/node-maintainer/src/wasm.rs).
+
+## Updating vendored `node-maintainer`
+
+Currently, this package vendors a prebuilt version of `node-maintainer` into
+the `./node-maintainer` directory. This has to be manually built and updated
+as needed whenever there are desired changes from orogene.
+
+To update the directory:
+
+1. `rm -rf ./node-maintainer`
+2. clone https://github.com/orogene/orogene somewhere. See the [contributing
+   instructions](https://github.com/orogene/orogene/blob/abba96e6662c3465a498fbe6154ffcf2fe33fac4/CONTRIBUTING.md#getting-up-and-running)
+   for a guide on how to set up and build wasm modules.
+3. `mv /path/to/orogene/crates/node-maintainer/pkg ./node-maintainer`
+4. `git add node-maintainer && git commit -m 'updated node-maintainer'
+
+## A Note on Build Requirements
+
+To get this branch working, as of today (4/7/2023), you need to use a
+TypeScript release that includes [this
+commit](https://github.com/microsoft/TypeScript/commit/d23b7e7c52c471732079a9834bbfeef53b1a1697),
+which has been merged into `main`, but not released yet.
+
+In order to use an unreleased TypeScript with VS Code:
+
+1. At the `../..` (`vscode/extensions/`) level, you should `npm link` the
+   version of typescript you want.
+	1. Go to your `typescript` source checkout
+	2. Call `npm link`
+	3. Go to `vscode/extensions`
+	4. Call `npm link typescript`
