+### Empty lines
+
+*Black* will allow single empty lines left by the original editors,
+except when they're added within parenthesized expressions.  Since such
+expressions are always reformatted to fit minimal space, this whitespace
+is lost.
+
+It will also insert proper spacing before and after function definitions.
+It's one line before and after inner functions and two lines before and
+after module-level functions.  *Black* will put those empty lines also
+between the function definition and any standalone comments that
+immediately precede the given function.  If you want to comment on the
+entire function, use a docstring or put a leading comment in the function
+body.

+Any tool that can pipe code through *Black* using its stdio mode (just
+[use `-` as the file name](http://www.tldp.org/LDP/abs/html/special-chars.html#DASHREF2)).
+The formatted code will be returned on stdout (unless `--check` was
+passed).  *Black* will still emit messages on stderr but that shouldn't
+affect your use case.

+There is currently no integration with any other text editors. Vim and
 Atom/Nuclide integration is planned by the author, others will require
 external contributions.
