+## Benchmarking
+
+For running benchmarks, you will need to [install hyperfine](https://github.com/sharkdp/hyperfine#installation) and optionally cmake.
+
+If you want to just run the benchmark for `comrak`, with the current state of the repo, you can simply run
+```bash
+make bench-comrak
+```
+
+This will build comrak in release mode, and run benchmark on it. You will see the time measurements as reported by hyperfine in the console.
+
+Makefile also provides a way to run benchmarks for `comrak` current state (with your changes), `comrak` main branch, [`cmark-gfm`](https://github.com/github/cmark-gfm), [`pulldown-cmark`](https://github.com/raphlinus/pulldown-cmark) and [`markdown-it.rs`](https://github.com/rlidwka/markdown-it.rs). For this you will need to install `cmake`. After that make sure that you have set-up the git submodules. In case you have not installed submodules when cloning, you can do it by running
+```bash
+git submodule update --init
+```
+
+After this is done, you can run 
+```bash
+make bench-all
+```
+
+which will run benchmarks across all, and report the time take by each as well as relative time.
+
+Apart from this, CI is also setup for running benchmarks when a pull request is first opened. It will add a comment with the results on the pull request in a tabular format comparing the 5 versions. After that you can manually trigger this CI by commenting `/run-bench` on the PR, this will update the existing comment with new results. Note benchmarks won't be automatically run on each push.
