+# Node Export
+
+This module allows users to export nodes and then import them it into another
+site, or the same site.It allows users to export/import
+nodes if they have the 'export nodes 'or 'export own nodes' permission, have node
+access to view the node and create the node type, and the node type is not 
+omitted in node export's settings. The module does not check access to the 
+filter formats used by the node's fields; please keep this in mind when assigning 
+permissions to user roles.
+

+## Usage
+
+1. To export nodes, either:
+  - Use the 'Node export' tab on a node page.
+  - Use the content tab (admin/content) and select the Export Option and then
+    there are two ways:
+    1. You can export all nodes of a particular content type.
+    1. You can provide all the node ids you want to export
+        wish to export and then choose 'Node export' under the
+        'Update options'.
+
+1. To import nodes that were exported with Node export, either:
+  - Use the form at 'Node export: import' under 'Admin/content'.
+  - Paste the export code you generated in export function and click submit.
+
+1. You can also export the nodes using drush command.
+
+  `drush ne-export 'nid' > 'filename'`
+
+  - For example, If you want to export node with node id 10 and the filename is
+    node.json then the command will be like:
+
+   `drush ne-export 10 > node.json`
+
+  - For more than one nodes, you can write their nids seprated by space.
+
+    `drush ne-export  1  3  4 > node.json`
