@@ -45,7 +45,7 @@ Here is a list of the additional settings currently supported by `haskell-langua
 - Max completions (`haskell.maxCompletions`, default 40): maximum number of completions sent to the LSP client.
 - Check project (`haskell.checkProject`, default true): whether to typecheck the entire project on initial load. As it is activated by default could drive to bad performance in large projects.
 - Check parents (`haskell.checkParents`, default `CheckOnSave`): when to typecheck reverse dependencies of a file; one of `NeverCheck`, `CheckOnSave` (means dependent/parent modules will only be checked when you save), or `AlwaysCheck` (means re-typechecking them on every change).
-- Session loading preference (`haskell.sessionLoading`, default `multipleComponents`): how to load sessions; one of `singleComponent` (means always loading only a single component when a new component is discovered) or `multipleComponents` (means always preferring loading multiple components in the cradle at once). `multipleComponents` might not be always possible, if the tool doesn't support multiple components loading. The cradle can decide how to handle these situations, and whether to honour the preference at all.
+- Components loading preference (`haskell.componentsLoading`, default `multi: needed-only`): which components to choose when loading sessions; one of `single` (means always loading only a single component when a new component is discovered), `multi: needed-only` (means preferring loading multiple components in the cradle at once, but only those needed for documents opened), `multi: whole-project` (means preferring loading all the components discovered from the cradle/project; see also `componentsToLoad` cradle config field). `multi: ...` might not be always possible, if the tool doesn't support multiple components loading. The cradle can decide how to handle these situations, and whether to honour the preference at all.
