+### Implementation Notes
+
+* `posts/` has the blog posts but really they can live in any directory. They need only the `post` tag to be added to this collection.
+* Add the `nav` tag to add a template to the top level site navigation. For example, this is in use on `index.njk` and `about/index.md`.
+* `about/index.md` shows how to add a content page.
+* Content can be any template format (blog posts needn’t be markdown, for example). Configure your supported templates in `.eleventy.js` -> `templateFormats`.
+* Because `css` and `png` are listed in `templateFormats` but are not supported template types, any files with these extensions will be copied without modification to the output (while keeping the same directory structure).
+* The blog post feed template is in `feed/feed.njk`. This is also a good example of using a global data files in that it uses `_data/metadata.json`.
+* This example uses three layouts:
+  * `_includes/layouts/base.njk`: the top level HTML structure
+  * `_includes/layouts/home.njk`: the home page template (wrapped into `base.njk`)
+  * `_includes/layouts/post.njk`: the blog post template (wrapped into `base.njk`)
+* `_includes/postlist.njk` is a Nunjucks macro and is used to display a list of all the posts. Use it like this:
+```
+{% import "postlist.njk" as postsm %}
+{{ postsm.list(collections.post, page) }}
+```
