+### Additional custom sentence terminators
+
+Additional sentence terminators can be added by setting
+`g:re_extra_sentence_term`.  For example, the following will count
+semicolons as sentence terminators:
+
+```vim
+let g:re_extra_sentence_term = '|;'
+
+call textobj#sentence#init()
+```
+
+Note this variable is a regular expression, and evey entry needs to be
+preceeded by `|`.
+
+The following can be used to count LaTeX environments as sentence
+terminators, which is convenient for automatic rewrapping (e.g., via
+`gqis`) that does not touch environments which are part of the sentence:
+
+```vim
+let g:re_extra_sentence_term =
+  \ '|\\begin\{[a-zA-Z]*\}' .
+  \ '|\\end\{[a-zA-Z]*\}'
+
+call textobj#sentence#init()
+```
