 ## Verbatim interpolated strings
 
-F# supports verbatim interpolated strings with triple quotes so that you can embed string literals.
+F# supports verbatim interpolated strings in two ways:
+
+### Using `$@` or `@$` prefix
+
+You can combine the interpolation prefix `$` with the verbatim string prefix `@` in any order. Verbatim strings ignore escape sequences (except for `""` to represent a quotation mark) and can span multiple lines. This is especially useful when working with file paths or strings containing backslashes and quotes.
+
+```fsharp
+let name = "Alice"
+let path = @"C:\Users\Alice\Documents"
+
+// Using $@ prefix
+printfn $@"User {name} has files in: {path}"
+
+// Using @$ prefix (also valid)
+printfn @$"User {name} has files in: {path}"
+
+// Embedding quotes - use "" to represent a single "
+let message = $@"He said ""{name}"" is here"
+```
+
+### Using triple quotes
+
+F# also supports verbatim interpolated strings with triple quotes so that you can embed string literals without escaping.
 
 ```fsharp
 let age = 30
