 ## Usage
 
-* Use `is::signals::bind_weak` instead of `std::bind` to ensure that nothing happens if method called when binded object already destroyed
+* Use `fastsignals::bind_weak` instead of `std::bind` to ensure that nothing happens if method called when binded object already destroyed
 * Pass pointer to T class method as first argument, `shared_ptr<T>` or `weak_ptr<T>` as second argument
 * Example: `bind_weak(&Document::save(), document, std::placeholders::_1)`, where `document` is a `weak_ptr<Document>` or `shared_ptr<Document>`
 
 ## Weak this idiom
 
-The `is::signals::bind_weak(...)` function implements "weak this" idiom. This idiom helps to avoid dangling pointers and memory access wiolations in asynchronous and/or multithreaded programs.
