+# BitGo sdk-coin-coredao
+
+SDK coins provide a modular approach to a monolithic architecture. This and all BitGoJS SDK coins allow developers to use only the coins needed for a given project.
+
+## Installation
+
+All coins are loaded traditionally through the `bitgo` package. If you are using coins individually, you will be accessing the coin via the `@bitgo/sdk-api` package.
+
+In your project install both `@bitgo/sdk-api` and `@bitgo/sdk-coin-coredao`.
+
+```shell
+npm i @bitgo/sdk-api @bitgo/sdk-coin-coredao
+```
+
+Next, you will be able to initialize an instance of "bitgo" through `@bitgo/sdk-api` instead of `bitgo`.
+
+```javascript
+import { BitGoAPI } from '@bitgo/sdk-api';
+import { Coredao } from '@bitgo/sdk-coin-coredao';
+
+const sdk = new BitGoAPI();
+
+sdk.register('coredao', Coredao.createInstance);
+```
+
+## Development
+
+Most of the coin implementations are derived from `@bitgo/sdk-core`, `@bitgo/statics`, and coin specific packages. These implementations are used to interact with the BitGo API and BitGo platform services.
+
+You will notice that the basic version of common class extensions have been provided to you and must be resolved before the package build will succeed. Upon initiation of a given SDK coin, you will need to verify that your coin has been included in the root `tsconfig.packages.json` and that the linting, formatting, and testing succeeds when run both within the coin and from the root of BitGoJS.
