+Introduction
+======================
+You have generated an MD-SAL module.
+
+* You should be able to successfully run ```mvn clean install``` on this project.
+
+Next Steps
+======================
+* run a ```mvn clean install``` if you haven't already. This will generate some code from the yang models.
+* Modify the model yang file under the model project.
+* Follow the comments in the generated provider class to wire your new provider into the generated 
+code.
+* Modify the generated provider model to respond to and handle the yang model. Depending on what
+you added to your model you may need to inherit additional interfaces or make other changes to
+the provider model.
+
+Generated Bundles
+======================
+* model
+    - Provides the yang model for your application. This is your primary northbound interface.
+* provider
+    - Provides a template implementation for a provider to respond to your yang model.
+* features
+    - Defines a karaf feature. If you add dependencies on third-party bundles then you will need to
+      modify the features.xml to list out the dependencies.
+* installer
+    - Bundles all of the jars and third party dependencies (minus ODL dependencies) into a single
+      .zip file.
+
+Usage
+======================
+## Purpose
+The purpose of this ODL feature is to support local and geo-redundancy by providing a way to
+back up and retrieve MD-SAL data exports to and from a Sonatype Nexus server. In order to function,
+this module requires the controller to have an installation of the ```data-export-import``` module and a valid export of MD-SAL data.
+
+## Backup
+MD-SAL Backup can be achieved using the ```daexim-offsite-backup:backup-data``` RPC either through the
+RESTConf portal or through a tool such as cURL or Postman. While no input is required for this RPC,
+the RPC does require the operational, models, and config .JSONs to be present in the daexim directory of the controller.
+```sh
+export USER=user
+export PASSWORD=password
+export ODL_HOST=https://yourhost.com:8181
+curl -X POST -u$USER:$PASSWORD ${ODL_HOST}/restconf/operations/daexim-offsite-backup:backup-data
+```
+Through this process a timestamped archive is created in the form of ```POD_NAME-yyyyMMdd_HH-odl_backup.zip``` 
+where ```POD_NAME``` is the name of the ODL, specified through the properties file or through an environment variable.
+
+## Retrieval
+MD-SAL Retrieval can be achieved by using the ```daexim-offsite-backup:retrieve-data``` RPC either through the
+RESTConf portal or through a tool such as cURL or Postman. This RPC requires timestamp information and may 
+be supplied with an optional podName.
+
+```sh
+export USER=user
+export PASSWORD=password
+export ODL_HOST=https://yourhost.com:8181
+export TARGET_ODL=targetOdlPodName
+export TIMESTAMP=yyyyMMdd_HH
+export DATA= '
+  {
+    "input": {
+      "pod-name": "'"$TARGET_ODL"'",
+      "timestamp": "'"$TIMESTAMP"'"
+    }
+  }'
+curl -X POST -u$USER:$PASSWORD --data $DATA ${ODL_HOST}/restconf/operations/daexim-offsite-backup:retrieve-data
+```
+
+Through this process an archive with the specified timestamp (and optional pod name) is downloaded from 
+the Nexus server and extracted into the controller's daexim directory. After this it is up to the user 
+to trigger an MD-SAL import.
+
+## Properties File
+Before each RPC execution this module pulls information from a user supplied properties file. The module expects to find:
+- daeximDirectory
+- credentials
+- nexusUrl
+- podName
+- file.operational
+- file.models
+- file.config
+
+> Refer to the example properties file
+
+If the module cannot find the properties file it will default to generic values and attempt to move forward.
