+zs is an extremely minimal static site generator written in Go.
+
+  - Keep your texts in markdown, or HTML format right in the main directory of your blog/site.
+  - Keep all service files (extensions, layout pages, deployment scripts etc) in the .zs subdirectory.
+  - Define variables in the header of the content files using YAML front matter:
+  - Use placeholders for variables and plugins in your markdown or html files, e.g. {{ title }} or {{ command arg1 arg2 }}.
+  - Write extensions in any language you like and put them into the .zs sub-directory.
+  - Everything the extensions prints to stdout becomes the value of the placeholder.
+
+Usage:
+  zs [command]
+
+Available Commands:
+  build       Builds the whole site or a single file
+  completion  Generate the autocompletion script for the specified shell
+  help        Help about any command
+  serve       Serves the site and rebuilds automatically
+  var         Display variables for the specified file

+## Frequently Asked Questions
