@@ -44,8 +44,8 @@ You can specify your own conditions and use them in any `condition` field:
 
 ```toml
 [conditions]
-arch64 = "CMAKE_SIZEOF_VOID_P EQUALS 8"
+arch64 = "CMAKE_SIZEOF_VOID_P EQUAL 8"
-arch32 = "CMAKE_SIZEOF_VOID_P EQUALS 4"
+arch32 = "CMAKE_SIZEOF_VOID_P EQUAL 4"
 ```
 
 This will make the `arch64` and `arch32` conditions available with their respective CMake expressions.
