+## Kleingrep
+
+Kleingrep is a regular expression engine, providing a library and command-line tool written in Go.
+
+It aims to provide a more featureful engine, compared to the one in
+[Go's standard library](https://pkg.go.dev/regexp), while retaining some semblance of efficiency.
+
+The engine does __not__ use backtracking, relying on the NFA-based method described in
+[Russ Cox's articles](https://swtch.com/~rsc/regexp). As such, it is immune to catastrophic backtracking.
+
+It also includes features not present in regexp, such as lookarounds and backreferences.
+
+### Syntax
+
+The syntax is, for the most part, a superset of Go's regexp. A full overview of the syntax can be found [here](https://pkg.go.dev/gitea.twomorecents.org/Rockingcool/kleingrep/regex#hdr-Syntax).
