+
+## Package Description
+The `rviz_simulator` is an interactive 3D environment built using RViz and Interactive Markers that can be used to generate fiducial target pixel locations.  
+
+
+## Installation Instructions
+Requires ROS Kinectic Kane.  
+
+Clone the repo into the `src` folder of your catkin workspace.
+Run `catkin_make` in the root of your workspace to build the `rviz_simulator` package.  
+
+### Required Dependencies
+- YAML-cpp [Installation Instructions](https://github.com/jbeder/yaml-cpp)
+- Eigen [Installation Instructions](http://eigen.tuxfamily.org/dox/GettingStarted.html)
+- Ceres [Installation Instructions](http://ceres-solver.org/installation.html)
+
+## Execution Instructions
+Edit the `initialize_simulator.yaml` file to change the simulator configuration.
+
+Naviate to the root of your catkin workspace and run the `simulate.launch` file with the following command:  
+> `roslaunch rviz_simulator simulate.launch`
+
+`simulate.launch` launches 2 nodes in normal mode:
+- `rviz`
+- `simulate`
+
+and 4 nodes in `debug_mode`:
+- `rviz`
+- `rqt_console`
+- `rqt_logger_level`
+- `simulate`
+
+To enter `debug_mode`, run the launch file with the command line arg 
+> `debug_mode:=true`
+
+By default, the `photoneo_camera_intrinsics.yaml` file is loaded. To specify another camera intrinsics file, run the launch file with the command line arg
+> `camera_intrinsics_file:=<camera_intrinsics_file_name.yaml>`  
+
+The `simulator` node creates a new folder `"detections_ROS_timestamp"` in the `rviz_simulator` package folder. A new detections folder with a new timestamp is created each time `roslaunch` is run.
+
+Drag around the virtual camera and multiple virtual fiducial targets.  
+
+Left click on the camera to generate a `YAML` file, in the created detections folder, with the measured target locations.
