+body:
+
+This method can be used to register a new publisher for a given URL scheme
+with Lektor.  This allows plugins to provide custom deployment methods.  For
+more information on implementing these see [Publisher :ref](../../publisher/).
+
+## Example
+
+```python
+from lektor.publisher import Publisher
+
+class MyPublisher(Publisher):
+    pass

+summary: The interface for extending the deployment process
+---
+type: class
+---
+body: 
+
+This class can be subclassed to implement custom deployment methods.
+Internally these are called “publishers” and to register them with the
+environment the [add_publisher :ref](../environment/add-publisher/) method can
+be used.
+
+Publishers have one method called [publish :ref](publish/) which is used to
+trigger the actual deployment process.  It also has a reference back to the
+environment it belongs to as well as the output path of the build process.
+
+For a minimal example of a publisher refer to the documentation of the
+[publish :ref](publish/) method.

+body:
+
+This method takes a message and raises an appropriate failure that aborts

+:ref](../publish/) method to indicate a failure:
+
+## Example
+
+```python
+from lektor.publisher import Publisher
+
+
+class MyPublisher(Publisher):
+    def publish(self, target_url, credentials=None, **extra):
+        self.fail('This publisher cannot publish :(')

+body:
+
+This attribute holds the path to the folder where the build process put the
+final artifacts.  Usually a publisher walks that folder and does something
+with all contents of it.  The publishers however are heavily encourated to
+ignore the special `.lektor` folder which contains lektor specific information
+that should not end up on the resulting server.

+title: publish
+---
+signature: target_url, credentials=None, **extra
+---
+summary: The method that triggers the deployment
+---
+type: method
+---
+version_added: 2.0
+---
+body:
+
+This method implements the actual publishing process.  It's supposed to
+implement a generator that reports the progress of the publishing.  If at any
+point something happens that would cause an error for the deployment this can
+be signalled with the [fail :ref](../fail/) method which aborts the execution
+and reports an error.
+
+The parameters to the function are as follows:
+
+* `target_url`: a URL object with the parsed URL.  This object comes from the
+  Werkzeug library and gives access to the individual parts of a URL by the
+  exposed attributes ([Read about the URL object :ext](http://werkzeug.pocoo.org/docs/0.11/urls/)).
+* `credentials`: an optional dictionary with command line supplied credentials.
+  Note that these credentials might be completely absent and the keys which are
+  provided might change with future versions of Lektor.
+* `**extra`: for forwards compatibility publishers are required to ignore extra
+  keyword arguments.
+
+## Example
+
+This example implements a simple publisher that just copies all built files
+into a new location.
+
+```python
+import os
+import shutil
+from lektor.publisher import Publisher
+
+
+class CopyPublisher(Publisher):
+
+    def publish(self, target_url, credentials=None, **extra):
+        src_path = self.output_path
+        dst_path = target_url.path
+        strip = len(src_path) + 1
+
+        for path, folders, filenames in os.walk(src_path):
+            # Ignore the .lektor folder.
+            folders[:] = [x for x in folders if x != '.lektor']
+
+            # Copy all files over
+            for filename in filenames:
+                full_path = os.path.join(src_path, path, filename)
+                dst = os.path.join(path, full_path[strip:])
+
+                # Make sure the destination folder exists.
+                try:
+                    os.makedirs(os.path.dirname(dst))
+                except (OSError, IOError):
+                    pass
+
+                # Copy the file
+                yield 'Copy %s' % filename
+                shutil.copy(full_path, dst)
+
+        yield 'Done'
+
+
+class MyPlugin(Plugin):
+    def on_setup_env(self, **extra):
+        self.env.add_publisher('copy', CopyPublisher)
+```
+
+This publisher registers with the `copy` scheme and could be used like this:
+
+```ini
+target_url = copy:///path/to/destination/folder
+```
