+1. Install [Visual Studio 2019](https://visualstudio.microsoft.com/downloads/).
+   The Community version is free for students, open-source contributors, and individuals.
+   Check "Desktop development with C++" in the Workloads tab, and uncheck C++ CMake Tools. We will install cmake via Conda.

+Open a Visual Studio Command Prompt (search for "x64 Native Tools Command Prompt for VS 2019" in the Windows search near the Start button).
+Right-click and run as Administrator.
+Optionally, right-click and pin to the task bar for quick access in the future.
+
+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>``.
+
+1. Install dependencies
+
+        conda install -c conda-forge colcon-common-extensions git cmake pkg-config
+
+1. Navigate to where you would like to build the library, and then clone the repository.
+   We will be using a [colcon](https://colcon.readthedocs.io/en/released/) workspace structure.
