+# Who am I?
+
+This examples shows how to use [`turnkey_client`](https://rubygems.org/gems/turnkey_client) to create a new sub-organization and a wallet. We generate a new Tron account (default account)
+
+To run this example:
+* `cp .env.example .env`
+* Follow the instructions in the `.env` file to fill in values for `TURNKEY_ORGANIZATION_ID`, `TURNKEY_API_PUBLIC_KEY`, `TURNKEY_API_PRIVATE_KEY`, and `SUB_ORGANIZATION_ROOT_PUBLIC_KEY`
+* Install the dependencies: `bundle install`
+* Then run the `create_sub_org.rb` script: `bundle exec ruby create_sub_org.rb`
+
+Here's an example run:
+
+```
+bundle exec ruby create_sub_org.rb
+Created new Turnkey sub-organization successfully
+Sub-Organization ID: 122da99b-db34-44ed-84ee-e326c5b149ec
+Tron wallet address: TZFeFMTfJKtkvHMhyveuYXSxKReBbmUiZw
+```
