+How to configure Tezos Reward Distributor?
+=====================================================
+
+Baker Configuration:
+------------------------
+
+Each baker has its own configuration and policy. A payment system should
+be flexible enough to cover needs of bakers. The application uses a yaml
+file for loading baker specific configurations.
+
+Configuration tool can be used to create baking configuration file
+interactively. Also an example configuration file is present under
+examples directory. For more information on configuration details, please
+see our wiki `page <https://github.com/habanoz/tezos-reward-distributor/wiki/Configuration>`_.
+
+TRD is designed to work as a linux service. It expects use of tezos
+signer for encrypted payment accounts. Unencrypted payment accounts can
+be used without tezos signer. If a payment account is encrypted and not
+configured to be signed by tezos signer, TRD will freeze. For more
+information on payment addresses please refer to our wiki `page <https://github.com/habanoz/tezos-reward-distributor/wiki/Payment-Address>`_.
+
+Email Setup
+------------------------
+
+Get emails for payment reports at each cycle. Fill email.ini file with
+your email details to receive payment emails.
+
+Fee Setup
+------------------------
+
+fee.ini file contains details about transaction fees. Currently the fee
+value specified under DEFAULT domain is used as fee amount. It is in
+mutez.

+Tezos Reward Distributor (Run & Forget) |Build Status|
+======================================================
+
+DISCLAIMER : TEZOS REWARD DISTRIBUTOR IS PROVIDED AS IS. IT IS UNDER
+CONSTANT DEVELOPMENT. EVENT THOUGH IT IS WELL TESTED, PLEASE USE WITH
+CARE. ALWAYS MAKE A PRE-RUN IN DRY MODE BEFORE MAKING ACTUAL PAYMENTS.
+IF YOU WANT TO RUN IN SERVICE MODE DO IT AFTER YOU ARE CONFIDENT WITH
+THE APPLICATION. IN SERVICE MODE DO NOT UPDATE OFTEN.
+
+What is Tezos Reward Distributor?
+------------------------------------------------
+
+TRD is a software for distributing baking rewards with delegators. This
+is not a script but a full scale application which can run in the
+background all the time. It can track cycles and make payments. It does
+not have to be used as a service, It can also be used interactively.
+
+TRD supports complex payments, pays in batches, provides two back ends
+for calculations: rpc and tzstats. It was developed and tested extensively by
+the community. For more information, please check following Medium article_
+and the source code which can be found in the following Github_ repo.

+
+Funding
+------------------------
+
+TRD is an open source project and will stay like this. It is not funded
+by any organization. A grant request is rejected by Tezos Foundation.
+However, I will try to continue to enhance the software and support the
+community.
