+A Markdown renderer on the Compute@Edge platform from Fastly.
+
+The main source file, `src/main.rs`, contains all the code for the renderer.
+The header and footer files I use are included at `content/_header.md` and
+`content/_footer.md` for easy inspection.
+
+## Nginx Configuration
+
+In order to best support this application, it's important to add the following
+line to Nginx's MIME types configuration:
+
+```text
+text/markdown     md;
+```
+
+I also disabled gzip and set the max-age and cache-control headers as follows:
+
+```nginx
+server {
+  # ...
+  location /edgeblog {
+    # To illustrate the source to visitors.
+    autoindex on;
+    autoindex_exact_size off;
+    autoindex_format html;
+    autoindex_localtime on;
+
+    # To facilitate tagging.
+    gzip off;
+
+    # Cache-Control headers
+    expires 1h;
+    add_header Cache-Control "public";
+  }
+}
+```
