+## Tokens
+
+Helfi platform config implements `hook_tokens()`. With the help of `helfi_platform_config.og_image_manager` service, it provides `[*:shareable-image]` token. Modules may implement services that handle this token for their entity types.
+
+Modules that use this system should still implement `hook_tokens_info` to provide information about the implemented token.
