+When building the website, you can set a theme by using `--theme` option. We suggest you to edit your configuration file and set the theme by default. Example with `config.toml` format.
+<!--more-->
+
+Import sample config from sample site to Hugo root:
+
+```
+$ cp themes/docdock/exampleSite/config.toml .
+```
+
+Change following `config.toml` line as needed, depending on method above:
+```
+theme = "<hugo-theme-docdock-dir-name>"
+```
+Comment out following line, so default `themes/` will be used:
+
+```
+# themesdir = "../.."
+```
+
+
+{{%excerpt%}}
+## Activate search
+
+If not already present, add the follow lines to the `config.toml` file.
+
+```toml
+[outputs]
+home = [ "HTML", "RSS", "JSON"]
+```
+{{% /excerpt%}}
+
+
+LUNRJS search index file will be generated on content changes.
+
+#### (Bonus)
+Create empty file `.gitkeep` inside `public/` and add following to `.gitignore`.  This way it will keep repo smaller and won't bring build result files and errors to remote checkout places:
+```
+/public/*
+!/public/.gitkeep
+```
+
+### Preview site
+```
+$ hugo server
+```
+to browse site on http://localhost:1313
