+# File Builder
+
+Type: `file`
+
+The `file` Packer builder is not really a builder, it just creates an artifact
+from a file. It can be used to debug post-processors without incurring high
+wait times. It does not run any provisioners.
+
+## Basic Example
+
+Below is a fully functioning example. It doesn't do anything useful, since no
+provisioners are defined, but it will connect to the specified host via ssh.
+
+``` {.javascript}
+{
+  "type":         "file",
+  "content":      "Lorem ipsum dolor sit amet",
+  "target":       "dummy_artifact"
+}
+```
+
+## Configuration Reference
+
+Configuration options are organized below into two categories: required and
+optional. Within each category, the available options are alphabetized and
+described.
+
+Any [communicator](/docs/templates/communicator.html) defined is ignored.
+
+### Required:
+
+-   `target` (string) - The path for a file which will be copied as the
+    artifact.
+
+### Optional:
+
+You can only define one of `source` or `content`. If none of them is
+defined the artifact will be empty.
+
+-   `source` (string) - The path for a file which will be copied as the
+    artifact.
+
+-   `content` (string) - The content that will be put into the artifact.
