+# Final Report
+
+This is a huge document that is a combination of a large number
+of other files from this course.
+
+This repository avoids commiting PDFs whenever possible (some files'
+original sources have been lost, and thus, only a PDF is available).
+Thus, LaTeX sources of all possible documents are submoduled,
+and compiled at build time.
+
+Some components of this document are generated from previously
+commited Markdown files to avoid redundancy. In particular,
+READMEs from all the code repositories and the REVIEW files
+containing code review feedback are used.
+
+For the most part (you still need to clone submodules),
+I specified the dependencies of this project in a Nix expression.
+Thus, to build this whole PDF:
+
+```
+nix-shell
+make
+```
+
+This should install all the required LaTeX packages and Pandoc,
+and generate an `archive.pdf` file.
