# Docblock Type Syntax

All docblock types are either [atomic types](type_syntax/atomic_types.md), [union types](type_syntax/union_types.md) or [intersection types](type_syntax/intersection_types.md).

Psalm supports PHPDoc’s [type syntax](https://docs.phpdoc.org/guides/types.html), and also the [proposed PHPDoc PSR type syntax](https://github.com/php-fig/fig-standards/blob/master/proposed/phpdoc.md#appendix-a-types).
