-# Example
+# Examples
+There's a number of examples found in the [examples](/examples/) folder, including loading g20 files, serialization, and custom factors.
+
+To run any of the examples, simply clone this repository and run,
+```bash
+cargo run --release --example g20 ./examples/data/M3500.g20
+```
+to visualize the optimization steps with [rerun](https://rerun.io) simply add `--features rerun` to the above command.
+
+Running the other examples can be done similarly,
+```bash
+cargo run --release --example serde --features serde
+cargo run --release --example gps
+``` 
+
+Additionally, we recommend checking out the [tests](/tests/) folder for more examples of custom noise models, residuals, robust kernels, and variables.
