+# None parser plugin for Embulk
+
+Embulk parser plugin not to parse at all
+
+## Install
+
+```
+$ embulk gem install embulk-parser-none
+```
+
+## Overview
+
+* **Plugin type**: parser
+* **Guess supported**: no
+
+## Configuration
+
+- **message_key**: A column name which this plugin outputs (string, default: "message")
+
+## Example
+
+```yaml
+in:
+  type: any file input plugin type
+  parser:
+    type: parser
+    format: none
+    message_key: message
+```
+
+Assume inputs are as following:
+
+```
+foo,bar,baz
+foo,bar,baz
+```
+
+then this plugin treats as:
+
++----------------+
+| message:string |
++----------------+
+| foo,bar,baz    |
+| foo,bar,baz    |
++----------------+
+
+## See also
+
+You may use [embulk-formatter-single_value](https://github.com/sonots/embulk-formatter-single_value) to recover outputs
