         For qsim software problems, we need to know the exact version you are
         using. If you are using the Python package and are running within a
         terminal emulator, then typing the following command in the shell will
-        print the version number:
-        ```
-        python3 -c 'import qsimcirq; print(qsimcirq.__version__)'
-        ```
+        print the version number:<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
+        ```python3 -c 'import qsimcirq; print(qsimcirq.__version__)'```<br>
         If you are using a Google Colab or Jupyter notebook environment,
         then running the following command in a notebook cell will print
-        the version number:
-        ```
-        import qsimcirq; print(qsimcirq.__version__)
-        ```
+        the version number:<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
+        `import qsimcirq; print(qsimcirq.__version__)`
