+The `dist-raw` directory contains JS sources that are distributed verbatim, not compiled nor typechecked via TS.
+
+To implement ESM support, we unfortunately must duplicate some of node's built-in functionality that is not
+exposed via an API.  We have copy-pasted the necessary code from https://github.com/nodejs/node/tree/master/lib
+then modified it to suite our needs.
+
+Formatting may be intentionally bad to keep the diff as small as possible, to make it easier to merge
+upstream changes and understand our modifications.  For example, when we need to wrap node's source code
+in a factory function, we will not indent the function body, to avoid whitespace changes in the diff.
+
+One obvious problem with this approach: the code has been pulled from one version of node, whereas users of ts-node
+run multiple versions of node.
+Users running node 12 may see that ts-node behaves like node 14, for example.
+
+## `raw` directory
+
+Within the `raw` directory, we keep unmodified copies of the node source files.  This allows us to use diffing tools to
+compare files in `raw` to those in `dist-raw`, which will highlight all of the changes we have made.  Hopefully, these
+changes are as minimal as possible.
+
+## Naming convention
+
+Not used consistently, but the idea is:
+
+`node-<directory>(...-<directory>)-<filename>.js`
+
+`node-internal-errors.js` -> `github.com/nodejs/node/blob/TAG/lib/internal/errors.js`
+
+So, take the path within node's `lib/` directory, and replace slashes with hyphens.
+
+In the `raw` directory, files are suffixed with the version number or revision from which
+they were downloaded.
+
+If they have a `stripped` suffix, this means they have large chunks of code deleted, but no other modifications.
+This is useful when diffing.  Sometimes our `dist-raw` files only have a small part of a much larger node source file.
+It is easier to diff `raw/*-stripped.js` against `dist-raw/*.js`.
