+Hacking on zsh-syntax-highlighting itself
+=========================================
+
+This document includes information for people working on z-sy-h itself: on the
+core driver (`zsh-syntax-highlighting.zsh`), on the highlighters in the
+distribution, and on the test suite.  It does not target third-party
+highlighter authors (although they may find it an interesting read).
+
+The `main` highlighter
+----------------------
+
+The following function `pz` is useful when working on the `main` highlighting:
+
+    pq() {
+      (( $#argv )) || return 0
+      print -r -l -- ${(qqqq)argv}
+    }
+    pz() {
+      local arg
+      for arg; do
+        pq ${(z)arg}
+      done
+    }
+
+It prints, for each argument, its token breakdown, similar to how the main
+loop of the `main` highlighter sees it.
+
+Testing the `brackets` highlighter
+----------------------------------
+
+Since the test harness empties `ZSH_HIGHLIGHT_STYLES` and the `brackets`
+highlighter interrogates `ZSH_HIGHLIGHT_STYLES` to determine how to highlight,
+tests must set the `bracket-level-#` keys themselves.  For example:
+
+    ZSH_HIGHLIGHT_STYLES[bracket-level-1]=
+    ZSH_HIGHLIGHT_STYLES[bracket-level-2]=
+
+    BUFFER='echo ({x})'
+
+    expected_region_highlight=(
+      "6  6  bracket-level-1" # (
+      "7  7  bracket-level-2" # {
+      "9  9  bracket-level-2" # }
+      "10 10 bracket-level-1" # )
+    )
+
+Testing the `pattern` highlighter
+---------------------------------
+
+Because the `pattern` highlighter modifies `region_highlight` directly instead
+of using `_zsh_highlight_add_highlight`, the test harness cannot get the
+`ZSH_HIGHLIGHT_STYLES` keys.  Therefore, when writing tests, use the style
+itself as third word (cf. the [documentation for `expected_region_highlight`]
+(docs/highlighters.md)).  For example:
+
+    ZSH_HIGHLIGHT_PATTERNS+=('rm -rf *' 'fg=white,bold,bg=red')
+
+    BUFFER='rm -rf /'
+
+    expected_region_highlight=(
+      "1 8 fg=white,bold,bg=red" # rm -rf /
+    )
+
+Miscellany
+----------
+
+If you work on the driver (`zsh-syntax-highlighting.zsh`), you may find the following zstyle useful:
+
+    zstyle ':completion:*:*:*:*:globbed-files' ignored-patterns {'*/',}zsh-syntax-highlighting.plugin.zsh

 * Create your script at
-    `highlighters/${myhighlighter}/${myhighlighter}-highlighter.zsh`.

-* Implement the `_zsh_highlight_myhighlighter_highlighter_predicate` function.
+* Implement the `_zsh_highlight_highlighter_acme_predicate` function.
   This function must return 0 when the highlighter needs to be called and
   non-zero otherwise, for example:
 
-        _zsh_highlight_myhighlighter_highlighter_predicate() {
+        _zsh_highlight_highlighter_acme_predicate() {
           # Call this highlighter in SVN working copies
           [[ -d .svn ]]
         }
 
-* Implement the `_zsh_highlight_myhighlighter_highlighter` function.

-  `region_highlight`, for example:
+* Implement the `_zsh_highlight_highlighter_acme_paint` function.
+  This function does the actual syntax highlighting, by calling
+  `_zsh_highlight_add_highlight` with the start and end of the region to
+  be highlighted and the `ZSH_HIGHLIGHT_STYLES` key to use. Define the default
+  style for that key in the highlighter script outside of any function with
+  `: ${ZSH_HIGHLIGHT_STYLES[key]:=value}`, being sure to prefix
+  the key with your highlighter name and a colon. For example:
 
-        _zsh_highlight_myhighlighter_highlighter() {
-          # Colorize the whole buffer with blue background
-          region_highlight+=(0 $#BUFFER bg=blue)
+        : ${ZSH_HIGHLIGHT_STYLES[acme:aurora]:=fg=green}
+
+        _zsh_highlight_highlighter_acme_paint() {
+          # Colorize the whole buffer with the 'aurora' style
+          _zsh_highlight_add_highlight 0 $#BUFFER acme:aurora
         }
 
+* Name your own functions and global variables `_zsh_highlight_acme_*`.
+
+    - In zsh-syntax-highlighting 0.4.0 and earlier, the entrypoints 
+        `_zsh_highlight_highlighter_acme_predicate` and
+        `_zsh_highlight_highlighter_acme_paint`
+        were named
+        `_zsh_highlight_acme_highlighter_predicate` and
+        `_zsh_highlight_highlighter_acme_paint` respectively.
+
+        These names are still supported for backwards compatibility;
+        however, support for them will be removed in a a future major or minor release (v0.x.0 or v1.0.0).
+
 * Activate your highlighter in `~/.zshrc`:
 
-        ZSH_HIGHLIGHT_HIGHLIGHTERS+=(myhighlighter)
+        ZSH_HIGHLIGHT_HIGHLIGHTERS+=(acme)

+### Useless trivia
+
+#### Forward compatibility.
+
+zsh-syntax-highlighting attempts to be forward-compatible with zsh.
+Specifically, we attempt to facilitate highlighting _command word_ types that
+had not yet been invented when this version of zsh-syntax-highlighting was
+released.
+
+A _command word_ is something like a function name, external command name, et
+cetera.  (See
+[Simple Commands & Pipelines in `zshmisc(1)`][zshmisc-Simple-Commands-And-Pipelines]
+for a formal definition.)
+
+If a new _kind_ of command word is ever added to zsh — something conceptually
+different than "function" and "alias" and "external command" — then command words
+of that (new) kind will be highlighted by the style `arg0_$kind`,
+where `$kind` is the output of `type -w` on the new kind of command word.  If that
+style is not defined, then the style `arg0` will be used instead.
