+### Building and Serving Multi-Language
+
+For multi-language MkDocs sites use the following additional steps:
+
+1. Add all new language *.md files to git commit: `git add docs/**/*.md -f`
+2. Build all languages to the `/site` directory. Verify that the top-level `/site` directory contains `CNAME`, `robots.txt` and `sitemap.xml` files, if applicable.
+
+    ```bash
+    # Remove existing /site directory
+    rm -rf site
+
+    # Loop through all *.yml files in the docs directory
+    for file in docs/*.yml; do
+      echo "Building MkDocs site with configuration file: $file"
+      mkdocs build -f "$file"
+    done
+    ```
+
+3. Preview in web browser with:
+
+    ```bash
+    cd site
+    python -m http.server
+    open http://localhost:8000  # on macOS
+    ```
