@@ -26,52 +26,52 @@ We've tried to put this tutorial together in a way that makes chapters
 easy to skip over if you are already familiar with or are uninterested
 in the various pieces. The structure of the tutorial is:
 
--  **`Chapter 1 <#language>`_: Introduction to the Kaleidoscope
+-  :ref:`Chapter 1 <chapter1anchor>`: **Introduction to the Kaleidoscope
    language, and the definition of its Lexer** -- This shows where we
    are going and the basic functionality that we want it to do. In order
    to make this tutorial maximally understandable and hackable, we
    choose to implement everything in Python instead of using lexer and
    parser generators. LLVM obviously works just fine with such tools,
    feel free to use one if you prefer.
 
--  **`Chapter 2 <PythonLangImpl2.html>`_: Implementing a Parser and
+-  `Chapter 2 <PythonLangImpl2.html>`_: **Implementing a Parser and
    AST** -- With the lexer in place, we can talk about parsing
    techniques and basic AST construction. This tutorial describes
    recursive descent parsing and operator precedence parsing. Nothing in
    Chapters 1 or 2 is LLVM-specific, the code doesn't even import the
    LLVM modules at this point. :)
 
--  **`Chapter 3 <PythonLangImpl3.html>`_: Code generation to LLVM IR**
+-  `Chapter 3 <PythonLangImpl3.html>`_: **Code generation to LLVM IR**
    -- With the AST ready, we can show off how easy generation of LLVM IR
    really is.
 
--  **`Chapter 4 <PythonLangImpl4.html>`_: Adding JIT and Optimizer
+-  `Chapter 4 <PythonLangImpl4.html>`_: **Adding JIT and Optimizer
    support** -- Because a lot of people are interested in using LLVM as
    a JIT, we'll dive right into it and show you the 3 lines it takes to
    add JIT support. LLVM is also useful in many other ways, but this is
    one simple and "sexy" way to shows off its power. :)
 
--  **`Chapter 5 <PythonLangImpl5.html>`_: Extending the Language:
+-  `Chapter 5 <PythonLangImpl5.html>`_: **Extending the Language:
    Control Flow** -- With the language up and running, we show how to
    extend it with control flow operations (if/then/else and a 'for'
    loop). This gives us a chance to talk about simple SSA construction
    and control flow.
 
--  **`Chapter 6 <PythonLangImpl6.html>`_: Extending the Language:
+-  `Chapter 6 <PythonLangImpl6.html>`_: **Extending the Language:
    User-defined Operators** -- This is a silly but fun chapter that
    talks about extending the language to let the user program define
    their own arbitrary unary and binary operators (with assignable
    precedence!). This lets us build a significant piece of the
    "language" as library routines.
 
--  **`Chapter 7 <PythonLangImpl7.html>`_: Extending the Language:
+-  `Chapter 7 <PythonLangImpl7.html>`_: **Extending the Language:
    Mutable Variables** -- This chapter talks about adding user-defined
    local variables along with an assignment operator. The interesting
    part about this is how easy and trivial it is to construct SSA form
    in LLVM: no, LLVM does *not* require your front-end to construct SSA
    form!
 
--  **`Chapter 8 <PythonLangImpl8.html>`_: Conclusion and other useful
+-  `Chapter 8 <PythonLangImpl8.html>`_: **Conclusion and other useful
    LLVM tidbits** -- This chapter wraps up the series by talking about
    potential ways to extend the language, but also includes a bunch of
    pointers to info about "special topics" like adding garbage
