@@ -4,13 +4,16 @@ Similar to Rust, Sway comes with its own standard library.
 
 The Sway Standard Library is the foundation of portable Sway software, a set of minimal shared abstractions for the broader Sway ecosystem. It offers core types, like `Result<T, E>` and `Option<T>`, library-defined operations on language primitives, native asset management, blockchain contextual operations, access control, storage management, and support for types from other VMs, among many other things.
 
-The standard library is made implicitly available to all Forc projects created using [`forc init`](../forc/commands/forc_init.md). Importing items from the standard library can be done using the `use` keyword. Example:
+The entire Sway standard library is a Forc project called `std`, and is available directly here: <https://github.com/FuelLabs/sway/tree/master/sway-lib-std> (navigate to the appropriate tagged release if the latest `master` is not compatible).
+
+## Using the Standard Library
+
+The standard library is made implicitly available to all Forc projects created using [`forc init`](../forc/commands/forc_init.md). In other words, it is not required to manually specify `std` as an explicit dependency. Forc will automagically use the version of `std` that matches its version.
+
+Importing items from the standard library can be done using the `use` keyword, just as importing items from any Sway project. For example:
 
 ```sway
 use std::address::Address;
 ```
 
-## Using the Standard Library
-
-Aside from the references to the standard library accross this book, you may also read the `std` library project directly [here](https://github.com/FuelLabs/sway/tree/master/sway-lib-std).

+This imports the `Address` type into the current namespace.
