+
+This package provides visual alignment for Org Mode, Markdown and
+table.el tables on GUI Emacs. It can properly align tables containing
+variable-pitch font, CJK characters and images. Meanwhile, the
+text-based alignment generated by Org mode (or Markdown mode) is left
+untouched.
+
+To use this package, load it and add `valign-mode' to `org-mode-hook' or
+`markdown-mode-hook':

+
+*Known problems:*
+• Hidden links in markdown still occupy the full length of the link,
+  because it uses character composition which we don’t support now.
+• Rendering large tables (≥100 lines) is laggy.
+
+*Note:*
+
+For table.el tables to work with valign, each cell has to have at least
+one space on the right and no space on the left.  You can use
+[ftable.el] to auto-layout the table for you.

+1 Install
+═════════
+
+  You can obtain valign.el from GNU ELPA by typing:
+  ┌────
+  │ M-x package-install RET valign RET
+  └────
+
+
+2 Customization
+═══════════════
+
+  Set `valign-fancy-bar' to `non-nil':
+
+  <./fancy-bar.png>
+
+  This only affects Org Mode and Markdown tables.
+
+  By default, valign doesn’t re-align the table after normal edit
+  commands like `self-insert-command' and `backward-kill-word'. If you
+  want valign to not re-align the table after a certain command, add
+  that command to `valign-not-align-after-list'.
+
+  Because valign isn’t particularly efficient, it doesn’t align tables
+  larger than 4000 characters in size. If you want to change that
+  behavior, customize `valign-max-table-size'. Valign puts
+  `valign-table-fallback' face on those large tables.
+
+  Other (less interesting) customization:
+  • `valign-signal-parse-error': Set to non-nil to be informed of parse
+    errors.
+  • `valign-lighter': Lighter in mode-line.
+  • `valign-box-charset-alist': Used for defining table.el tables, e.g.,
+    Unicode/ASCII tables.
+
+
+3 If function advice makes you itch
+═══════════════════════════════════
+
+  `valign-mode' adds advice and doesn’t remove them even if you close
+  `valign-mode' because function advice is global and `valign-mode' is
+  local. If you want to remove the advice, use
+  `valign-remove-advice'. If you run this while some buffer still has
+  `valign-mode' on, they break.
