+When creating objects in the web interface, you can use HTTP parameters to
+prefill fields in the form. This allows you to quickly create a link to a
+form with some of the fields already filled in with default values.
+
+To prefill a form, start by finding the URI for the form you want to prefill.
+Do this by navigating to the relevant application, clicking the "Create" button
+for the type of object you want to create, and then copying the URI out of your
+browser's address bar. It will usually look something like this:
+
+```
+%s
+```
+
+However, `your.install.com` will be the domain where your copy of Phabricator
+is installed, and `application/` will be the URI for an application. Some
+applications have multiple forms for creating objects or URIs that look a little
+different than this example, so the URI may not look exactly like this.
+
+To prefill the form, add properly encoded HTTP parameters to the URI. You
+should end up with something like this:
+
+```
+%s?title=Platyplus&body=Ornithopter
+```
+
+If the form has `title` and `body` fields of the correct types, visiting this
+link will prefill those fields with the values "Platypus" and "Ornithopter"
+respectively.
+
+The rest of this document shows which parameters you can add to this form and
+how to format them.

+
+Supported Fields
+----------------
+
+This form supports these fields:
+
+EOTEXT
+      ,
+      $uri,
+      $uri);
+
+    $rows = array();
+    foreach ($fields as $field) {
+      $rows[] = array(
+        $field->getLabel(),
+        $field->getKey(),
+        $field->getHTTPParameterType(),
+        $field->getDescription(),
+      );
+    }
+
+    $main_table = id(new AphrontTableView($rows))
+      ->setHeaders(
+        array(
+          pht('Label'),
+          pht('Key'),
+          pht('Type'),
+          pht('Description'),
+        ))
+      ->setColumnClasses(
+        array(
+          'pri',
+          null,
+          null,
+          'wide',
+        ));
+
+    $aliases_text = pht(<<<EOTEXT
+Aliases
+-------
+
+Aliases are alternate recognized keys for a field. For example, a field with
+a complex key like `examplePHIDs` might be have a simple version of that key
+as an alias, like `example`.
+
+Aliases work just like the primary key when prefilling forms. They make it
+easier to remember and use HTTP parameters by providing more natural ways to do
+some prefilling.
+
+For example, if a field has `examplePHIDs` as a key but has aliases `example`
+and `examples`, these three URIs will all do the same thing:
+
+```
+%s?examplePHIDs=...
+%s?examples=...
+%s?example=...
+```
+
+If a URI specifies multiple default values for a field, the value using the
+primary key has precedence. Generally, you can not mix different aliases in
+a single URI.
