+
+## Learning About Tracers
+
+The project [Algorithm Visualizer](https://github.com/algorithm-visualizer) has a visualization library in each
+supported language ([JavaScript](https://github.com/algorithm-visualizer/tracers.js)
+, [C++](https://github.com/algorithm-visualizer/tracers.cpp),
+and [Java](https://github.com/algorithm-visualizer/tracers.java)) to visualize codes.
+
+There are five tracers in the library to visualize different types of data:
+
+- [Array1DTracer](https://github.com/algorithm-visualizer/algorithm-visualizer/wiki/Array1DTracer)
+- [Array2DTracer](https://github.com/algorithm-visualizer/algorithm-visualizer/wiki/Array2DTracer)
+- [ChartTracer](https://github.com/algorithm-visualizer/algorithm-visualizer/wiki/ChartTracer)
+- [GraphTracer](https://github.com/algorithm-visualizer/algorithm-visualizer/wiki/GraphTracer)
+- [LogTracer](https://github.com/algorithm-visualizer/algorithm-visualizer/wiki/LogTracer)
+
+There are also randomizers to help you create random data.
+
+Check out the [API reference](https://github.com/algorithm-visualizer/algorithm-visualizer/wiki) for more information.
+
+## Making Your Visualization Public
+
+If you think other people would find your visualization useful, you can add it to the side menu
+by [contributing to `algorithm-visualizer/algorithms`](https://github.com/algorithm-visualizer/algorithms/blob/master/CONTRIBUTING.md)
+.
