-Welcome to the Rust documentation! You can use the section headings above
-to jump to any particular section.
-
-# Getting Started
-
-If you haven't seen Rust at all yet, the first thing you should read is the [30
-minute intro](intro.html). It will give you an overview of the basic ideas of Rust
-at a high level.
-
-Once you know you really want to learn Rust, the next step is reading [the
-guide](guide.html). It is a lengthy explanation of Rust, its syntax, and its
-concepts. Upon completing the guide, you'll be an intermediate Rust developer,
-and will have a good grasp of the fundamental ideas behind Rust.
-
-# Community & Getting Help
-
-If you need help with something, or just want to talk about Rust with others,
-there's a few places you can do that:
-
-The Rust IRC channels on [irc.mozilla.org](http://irc.mozilla.org/) are the
-fastest way to get help.
-[`#rust`](http://chat.mibbit.com/?server=irc.mozilla.org&channel=%23rust) is
-the general discussion channel, and you'll find people willing to help you with
-any questions you may have.
-
-There are also three specialty channels:
-[`#rust-gamedev`](http://chat.mibbit.com/?server=irc.mozilla.org&channel=%23rust-gamedev)
-and
-[`#rust-osdev`](http://chat.mibbit.com/?server=irc.mozilla.org&channel=%23rust-osdev)
-are for game development and operating system development, respectively.
-There's also
-[`#rust-internals`](http://chat.mibbit.com/?server=irc.mozilla.org&channel=%23rust-internals), which is for discussion of the development of Rust itself.
-
-You can also get help on [Stack
-Overflow](http://stackoverflow.com/questions/tagged/rust). Searching for your
-problem might reveal someone who has asked it before!
-
-There is an active [subreddit](http://reddit.com/r/rust) with lots of
-discussion about Rust.
-
-There is also a [developer forum](http://discuss.rust-lang.org/), where the
-development of Rust itself is discussed.

-### Vector, Array, and Slice types
+### Vector types
 
-Rust has three different types for a list of items:
+The vector type constructor represents a homogeneous array of values of a given type.
+A vector has a fixed size.
+(Operations like `vec.push` operate solely on owned vectors.)
+A vector type can be annotated with a _definite_ size, such as `[int, ..10]`.
+Such a definite-sized vector type is a first-class type, since its size is known statically.
+A vector without such a size is said to be of _indefinite_ size,
+and is therefore not a _first-class_ type.
+An indefinite-size vector can only be instantiated through a pointer type,
+such as `&[T]` or `Vec<T>`.
+The kind of a vector type depends on the kind of its element type,
+as with other simple structural types.
 
-* `Vec<T>`, a 'vector'
-* `[T ..N]`, an 'array'
-* `&[T]`, a 'slice'.
+Expressions producing vectors of definite size cannot be evaluated in a
+context expecting a vector of indefinite size; one must copy the
+definite-sized vector contents into a distinct vector of indefinite size.
 
-A vector is a heap-allocated list of `T`. A vector has ownership over the data
-inside of it. It is also able to grow and change in size. It's important to note
-that `Vec<T>` is a library type, it's not actually part of the core language.
+An example of a vector type and its use:
 
-An array has a fixed size, and can be allocated on either the stack or the heap.
-
-A slice is a 'view' into a vector or array. It doesn't own the data it points
-to, it borrows it.
-
-An example of each kind:
-
-```{rust}
-let vec: Vec<int>  = vec![1, 2, 3];
-let arr: [int, ..3] = [1, 2, 3];
-let s: &[int]      = vec.as_slice();
-```
-
-As you can see, the `vec!` macro allows you to create a `Vec<T>` easily. The
-`vec!` macro is also part of the standard library, rather than the language.
+~~~~
+let v: &[int] = &[7, 5, 3];
+let i: int = v[2];
+assert!(i == 3);
+~~~~
 
-All in-bounds elements of vectors, arrays, and slices are always initialized,
-and access to a vector, array, or slice is always bounds-checked.
+All in-bounds elements of a vector are always initialized,
+and access to a vector is always bounds-checked.
