 Citation rendering
 ------------------
 
+`--bibliography=`*FILE*
+:   Set the `bibliography` field in the document's metadata to *FILE*,
+    overriding any value set in the metadata, and tell pandoc to
+    use the `pandoc-citeproc` filter.  (This is equivalent to the
+    combination `--metadata bibliography=FILE --filter pandoc-citeproc`.)
+    Note that an error will result unless `pandoc-citeproc` is installed.
+
+`--csl=`*FILE*
+:   Set the `csl` field in the document's metadata to *FILE*,
+    overriding any value set in the metadata.  (This is equivalent to
+    `--metadata csl=FILE`.)
+
+`--citation-abbreviations=`*FILE*
+:   Set the `citation-abbreviations` field in the document's metadata to
+    *FILE*, overriding any value set in the metadata.  (This is equivalent to
+    `--metadata citation-abbreviations=FILE`.)
+
 `--natbib`
 :   Use natbib for citations in LaTeX output.
