+### [blackd](https://github.com/psf/black)
+
+blackd is a small HTTP server that exposes Black’s functionality over a simple protocol. The main benefit of using it is to avoid the cost of starting up a new Black process every time you want to blacken a file. The only way to configure the formatter is by using the provided config options, it will not pick up on config files.
+
+#### Usage
+
+```lua
+local sources = { null_ls.builtins.formatting.blackd }

+Port to listen on. Defaults to 45484.
+##### `line_length` (number)
+
+Set how many characters per line to allow. Defaults to 88.
+##### `skip_source_first_line` (boolean)
+
+If set to true, the first line of the source code will be ignored. Defaults to false.
