+## Welcome
+
+This repository is in a bit of a transition state right now because I am
+migrating the framework and hosting for this site.
+
+This is a major overhaul, all new code is on the way!
+
+| Category  | Old                                      | New                           |
+| --------- | ---------------------------------------- | ----------------------------- |
+| Framework | [Jekyll](https://jekyllrb.com)           | [Next.js](https://nextjs.org) |
+| Hosting   | [GitHub Pages](https://pages.github.com) | [Vercel](https://vercel.com)  |
+
+## Structure
+
+In the meantime, all old code from the Jekyll site will be in the
+[`jekyll` directory](./jekyll) and the new code for the Next.js site will be in
+the [`next` directory](./next).
+
+The idea here is some pieces, like post content markdown files, can be moved
+over. For the pieces that will be eventually deleted, this just lets me view
+them easily in parallel without them conflicting with each other.
+
+Eventually, the `jekyll` folder will be destroyed and the contents of the `next`
+folder will live here at the repo root. Someday. 🙂
