+   Check "Desktop development with C++" in the Workloads tab, and uncheck C++ CMake Tools. We will install cmake via Conda.

+If you did not add Conda to your ``PATH`` environment variable during Conda installation, you may need to navigate to the location of ``condabin`` in order to use the `conda` command.
+To find ``condabin``, search for "Anaconda Prompt" in the Windows search near the Start button, open it, run ``where conda``, and look for a line containing the directory ``condabin``.
+
+1. Navigate to your ``condabin`` if necessary, and then create and activate a Conda environment:
+
+        conda create -n ign-ws
+        conda activate ign-ws
+
+   Once you have activated an environment, a prefix like ``(ign-ws)`` will be prepended to your prompt, and you can use the ``conda`` command outside of ``condabin``.
+
+   You can use ``conda info --envs`` to see all your environments.
+
+   To remove an environment, use``conda env remove --name <env_name>``.
