+
+#### Install Prerequisites
+
+First, follow the [ign-cmake](https://github.com/ignitionrobotics/ign-cmake) tutorial for installing Conda, Visual Studio, CMake, etc., prerequisites, and creating a Conda environment.
+
+Navigate to ``condabin`` if necessary to use the ``conda`` command (i.e., if Conda is not in your `PATH` environment variable. You can find the location of ``condabin`` in Anaconda Prompt, ``where conda``).
+
+Create if necessary, and activate a Conda environment:
+
+```
+conda create -n ign-ws
+conda activate ign-ws
+```
+
+Install Ignition dependencies, replacing `<#>` with the desired versions:
+
+```
+conda install libignition-cmake<#> libignition-common<#> libignition-math<#> libignition-transport<#> libignition-msgs<#> libignition-plugin<#> --channel conda-forge
+```
+
+Before [ign-rendering](https://github.com/ignitionrobotics/ign-rendering) becomes available on conda-forge, follow its tutorial to build it from source.
+
+#### Build from source
+
+1. Activate the Conda environment created in the prerequisites:
+
+    ```
+    conda activate ign-ws
+    ```
+
+1. Navigate to where you would like to build the library, and clone the repository.
+
+    ```
+    # Optionally, append `-b ign-sensors#` (replace # with a number) to check out a specific version
+    git clone https://github.com/ignitionrobotics/ign-sensors.git
+    ```
+
+1. Configure and build
+
+    ```
+    cd ign-sensors
+    mkdir build
+    cd build
+    ```
+
+    Before ``ign-rendering`` becomes available on conda-forge, we need to build it from source and specify the path containing ``ignition-rendering-config.cmake`` in ``CMAKE_PREFIX_PATH``, for cmake to find ``ign-rendering``. That path could be ``ign-rendering-install-path\lib\cmake\ignition-rendering4``, for example.
+
+    ```
+    cmake .. -DBUILD_TESTING=OFF -DCMAKE_PREFIX_PATH=path\containing\ignition-rendering-config  # Optionally, -DCMAKE_INSTALL_PREFIX=path\to\install
+    cmake --build . --config Release
+    ```
+
+1. Optionally, install
 
+    ```
+    cmake --install . --config Release
+    ```
