+# regex
+
+There are 2 ways to do regex:
+1. using the native module called `regex`.
+2. using an external module called `pcre`, which wraps the C library pcre.
+
+> [!NOTE]
+> You need to first do: `v install pcre`, for the `pcre` module to work.
+
+You can find examples of both in this directory.
