 # Building Documentation

+## Current-Version Documentation
 
-1. Install the dependencies for [Sphinx](https://www.sphinx-doc.org/en/master/):
+This section describes how to build the documentation for the current version of the project.
 
-    ```bash
-    # enter the location where this readme exists

+# 1. Navigate to the docs directory and install dependencies
+cd docs
+pip install -r requirements.txt
 
-    ```bash
-    # make the html version
-    make html
-    ```
+# 2. Build the current documentation
+make current-docs
 
-3. The documentation is now available at `docs/_build/html/index.html`:
+# 3. Open the current docs
+xdg-open _build/current/index.html
