+Query Based Custom Clang-Tidy Checks
+====================================
+
+Introduction
+============
+
+This page provides examples of how to add query based custom checks for
+:program:`clang-tidy`.
+
+Custom checks are based on clang-query syntax. Every custom checks will be
+registered in `custom` module to avoid name conflict. They can be enabled or
+disabled by the checks option like the builtin checks.
+
+Custom checks support inheritance from parent configurations like other
+configuration items.
+
+Configuration
+=============
+
+`CustomChecks` is a list of custom checks. Each check must contain
+  - Name: check name can been used in `-checks` option.
+  - Query: query string
+  - Diagnostic: list of diagnostics to be reported.
+     - BindName: name of the node to be bound in `Query`.
+     - Message: message to be reported.
+     - Level: severity of the diagnostic, the possible val...
