 ### Nested Schema for `set_list`
@@ -289,7 +288,7 @@ resource "helm_release" "example" {
 The `set`, `set_list`, and `set_sensitive` blocks support:
 
 * `name` - (Required) full name of the variable to be set.
-* `value` - (Required) value of the variable to be set.
+* `value` - (Required; Optional for `set`) value of the variable to be set.
 * `type` - (Optional) type of the variable to be set. Valid options are `auto` and `string`.
 
 Since Terraform Utilizes HCL as well as Helm using the Helm Template Language, it's necessary to escape the `{}`, `[]`, `.`, and `,` characters twice in order for it to be parsed. `name` should also be set to the `value path`, and `value` is the desired value that will be set.
