+# FollieHiyuki's CDN
+
+This is a small website, acting like a centralized source for all of my web assets. Most of them are vendored fonts and small CSS files.
+
+The website is deployed to Cloudflare Pages and is available at <https://cdn.folliehiyuki.com>.
+
+## FAQ
+
+> Why not `<link href="url-to-original-source">`?
+
+I like being in control of my own stuff. Also, it's because my websites have a strict `Content-Security-Policy` header value (see [_headers](./src/_headers) file for an example).
+
+> Why not using Chrome or Nginx directory listing?
+
+I like some theming and little directory/file icons. Also, CloudFlare Pages (where I deploy this project to) isn't a VM hosting platform but a [FaaS](https://en.wikipedia.org/wiki/Function_as_a_Service) provider.
+
+> Why not using `tree(1)`?
+
+```bash
+$ find ./out/ -mindepth 1 -type d -print -exec sh -c 'tree "$0" \
+	-a \
+	-i \
+	-F \
+	-H "." \
+	-I "index.html" \
+	-T "$0" \
+	-L 1 \
+	-o "$0/index.html" \
+	--noreport \
+	--dirsfirst \
+	--charset utf-8 \
+	--ignore-case' {} \;
+```
+
+Meh?
+
+Also, `tree` injects its metadata, CSS and copyright notice into the `index.html` file. Yes, I can yank them out with something like [htmlq](https://github.com/mgdm/htmlq), but I also want to insert my own styling and stuff.
+
+> Why not using [minify](https://github.com/tdewolff/minify)'s library but its CLI?
+
+Using the CLI is much easier. And, I don't want a dedicated Go module for this small project with external dependencies.
+
