+
+Baselined versions of this document can be obtained from DocuShare at https://ls.st/LSE-61.
+
+This repository hosts reports from the LSE-61 MagicDraw model in LaTeX format.
+
+To generate a new version of the document from the model follow the instructions in the Latex section of the `MagicDraw-macros`_ repository (in ``docgen_templates/latex``).
+
+Check that it builds before committing the generated LSE-61.
+The document requires the `lsst-texmf`_ LaTeX classes are available.
+
+The document title, author, date, document handle, and change record are defined in the file ``metadata.tex``.
+This allows you to specify these outside of the generic MagicDraw template file.
