+# Introduction
+
+In Cairo, there's no native type for strings. Instead, you can use a single `felt252` to store a short string of up to 31 characters, or a `ByteArray` for strings of arbitrary length. Short strings use single quotes and `ByteArray` uses double quotes. All characters must follow the ASCII standard.
