+# Marks Across Vim Sessions
+
+Any mark set with a capital letter (that is, `A-Z`) is called a *file mark*.
+File marks can be used to move from file to file. File marks will also be
+written to the Vim Info file (`~/.viminfo`) which means that if you close
+Vim and open it again, it will still know about those file marks. This means
+that your file marks are persisted across vim sessions which will save you
+the trouble of having to redefine them each time.
+
+A more detailed description of marks is at `:help marks`.
