This tutorial will show you how to create a simple theme in Hugo. I assume that you are familiar with HTML, the bash command line, and that you are comfortable using Markdown to format content. I'll explain how Hugo uses templates and how you can organize your templates to create a theme. I won't cover using CSS to style your theme.
-We'll start with creating a new site with a very basic template. Then we'll add in a few pages and posts. With small variations on that, you will be able to create many different types of web sites.

Skins are the files responsible for the look and feel of your site. It’s the CSS that controls colors and fonts, it’s the Javascript that determines actions and reactions. It’s also the rules that Hugo uses to transform your content into the HTML that the site will serve to visitors.
-You have two ways to create a skin. The simplest way is to create it in the ```layouts/``` directory. If you do, then you don’t have to worry about configuring Hugo to recognize it. The first place that Hugo will look for rules and files is in the ```layouts/``` directory so it will always find the skin.

### The Home Page
-The home page, or landing page, is the first page that many visitors to a site see. It is the index.html file in the root directory of the web site. Since Hugo writes files to the public/ directory, our home page is public/index.html.
+The home page, or landing page, is the first page that many visitors to a site see. It is the `index.html` file in the root directory of the web site. Since Hugo writes files to the `public/` directory, our home page is `public/index.html`.
### Site Configuration File
When Hugo runs, it looks for a configuration file that contains settings that override default values for the entire site. The file can use TOML, YAML, or JSON. I prefer to use TOML for my configuration files. If you prefer to use JSON or YAML, you’ll need to translate my examples. You’ll also need to change the name of the file since Hugo uses the extension to determine how to process it.
-Hugo translates Markdown files into HTML. By default, Hugo expects to find Markdown files in your ```content/``` directory and template files in your ```themes/``` directory. It will create HTML files in your ```public/``` directory. You can change this by specifying alternate locations in the configuration file.

#### Front Matter
-The front matter is information about the content. Like the configuration file, it can be written in TOML, YAML, or JSON. Unlike the configuration file, Hugo doesn’t use the file’s extension to know the format. It looks for markers to signal the type. TOML is surrounded by “`+++`”, YAML by “`---`”, and JSON is enclosed in curly braces. I prefer to use TOML, so you’ll need to translate my examples if you prefer YAML or JSON.

-A partial template is a template that can be included in other templates. Partial templates must be called using the “partial” template command. They are very handy for rolling up common behavior.

That way if you decide to change the banner, you only have to change the partial template.

### Generate the HTML For the New Site
Running the `hugo` command with no options will read all the available content and generate the HTML files. It will also copy all static files (that's everything that's not content). Since we have an empty site, it won't do much, but it will do it very quickly.

### Update the Configuration File to Use the Theme
Now that we've got a theme to work with, it's a good idea to add the theme name to the configuration file. This is optional, because you can always add "-t zafta" on all your commands. I like to put it the configuration file because I like shorter command lines. If you don't put it in the configuration file or specify it on the command line, you won't use the template that you're expecting to.

-Notice four things:
+It's similar to what we had without a theme. We'd expect that since our theme has only empty templates. But notice that Hugo created `css/` and `js/` directories. That's due to our template having those in its `static/` directory:
-1. Hugo created a home page. This is the file public/index.html.
-2. Hugo created a css/ directory.
-3. Hugo created a js/ directory.
-4. Hugo claimed that it created 0 pages. It created a file and copied over static files, but didn't create any pages. That's because it considers a "page" to be a file created directly from a content file. It doesn't count things like the index.html files that it creates automatically.
+```bash
+$ ls -l themes/zafta/static/

+drwxr-xr-x 2 mdhender wheel 68 Nov 27 20:35 js
+$
+```
+
+The rule with static files is simple: Hugo copies them over without any changes.
#### The Home Page
-Hugo supports many different types of templates. The home page is special because it gets its own type of template and its own template file. The file, layouts/index.html, is used to generate the HTML for the home page. The Hugo documentation says that this is the only required template, but that depends. Hugo's warning message shows that it looks for three different templates:

When Hugo created our theme, it created an empty home page template. Now, when we build the site, Hugo finds the template and uses it to generate the HTML for the home page. Since the template file is empty, the HTML file is empty, too. If the template had any rules in it, then Hugo would have used them to generate the home page.

Hugo does two things when generating the site. It uses templates to transform content into HTML and it copies static files into the site. Unlike content, static files are not transformed. They are copied exactly as they are.
-Hugo assumes that your site will use both CSS and JavaScript, so it creates directories in your theme to hold them. Remember opinions? Well, Hugo's opinion is that you'll store your CSS in a directory named css/ and your JavaScript in a directory named js/.
