+
+== The core system
+
+#TeX (1978) forms the foundation - Donald Knuth's low-level typesetting engine
+that handles the core mathematics of digital typography. Think of it as assembly
+language for documents. Example:
+
+```tex
+\hbox{\bf\tenpoint Introduction}
+\vskip 12pt
+```
+
+== Introducing usability
+
+#LaTeX (1984) is Leslie Lamport's layer over #TeX that introduces logical
+markup, making document creation more intuitive:
+
+```latex
+\section{Introduction}
+```
+
+== Standardization and packages
+
+#LaTeX2E (1994) standardized #LaTeX, adding robust package management and fixing
+incompatibilities between different #LaTeX styles.
+
+== PDF integration
+
+#pdfTeX (1996) added direct PDF output, with font embedding, microtypography
+  features like margin kerning and font expansion, and PDF-specific features
+  like hyperlinks and tables of contents. It became the default #TeX engine for
+  most #LaTeX installations:
+
+```tex
+\pdfoutput=1
+\pdfcompresslevel=0
+\pdfobjcompresslevel=0
+\pdfmapline{ptmr8r Times-Roman 2 <8r.enc}
+\font\tenrm=ptmr8r
+\tenrm
+Welcome to pdf\TeX!
+\end
+```
+
+== Modern fonts and scripting
+
+Two modern branches evolved to handle Unicode and modern fonts:
+
+#XeTeX (2004): A #TeX engine supporting Unicode and modern fonts.
+#XeLaTeX enables commands like:
+
+```latex
+\usepackage{fontspec}
+\setmainfont{Helvetica Neue}
+```
+
+#LuaTeX (2007): #TeX engine with embedded Lua scripting.
+#LuaLaTeX allows direct programming:
+
+```latex
+\directlua{
+  local x = 1 + 1
+  tex.print(x)
+}
+```
+
+== Typical use
+
+Modern workflows typically use #XeLaTeX for straightforward Unicode documents
+  and #LuaLaTeX when document generation requires programming logic. Both are
+  vast improvements over the original #TeX:
+
+Original #TeX:
+
+```tex
+\font\x="Times New Roman" at 12pt
+\x Hello, 世界
+```
+
+#XeLaTeX/#LuaLaTeX:
+
+```latex
+\documentclass{article}
+\usepackage{fontspec}
+\setmainfont{Times New Roman}
+\begin{document}
+Hello, 世界
+\end{document}
+```
+
+== The Modern alternative: Typst
+
+Typst (2023) is a modern competitor to the #TeX family, designed from scratch
+with a focus on speed and intuitive syntax:
+
+```typst
+= Fibonacci sequence
+The Fibonacci sequence is defined by
+$F_n = F_(n-1) + F_(n-2)$.
+
+#let fib(n) = (
+  if n <= 2 { 1 }
+  else { fib(n - 1) + fib(n - 2) }
+)
+
+The 8th Fibonacci number is #fib(8).
+```
