+## Usage
+
+### First initialiization
+
+1. You can create brand new creator coin just by passing reward basis points before you go to buy and sell
+
+    ```php
+    use Muvon\Bitclout\CreatorCoin;
+    $Coin = CreatorCoin::create(0); // pass reward basis points
+    ```
+
+2. You can initialize creator coin by locked amount and coins sold
+
+    ```php
+    use Muvon\Bitclout\CreatorCoin;
+    $Coin = CreatorCoin::create(0); // pass reward basis points
+    $Coin->init(1000, 1000); // locked and supply in nanos
+    ```
+
+### Emulate buys
+
+One you created object you can buy and sell using buy and sell methods
+
+Lets buy for 1 $CLOUT
+
+```php
+$Coin->buy(1 * 10 ** 9);
+
+// Check rate, locked and supply
+var_dump($Coin->getLocked());
+var_dump($Coin->getSupply());
+var_dump($Coin->getRate());
+
+// Check info about minting of last buy
+var_dump($Coin->getLastBuy());
+```
+
+Sell is easy as buy just pass creator coins in nanos
+
+```php
+$Coin->sell(1 * 10 ** 9);
+```
+
+### Strategies
+
+BitClout fixed some issues and fully changed creator coin stretegies after initial launch. To control emulation of it you need to pass strategy byself or set block height by method.
+
+```php
+// Latest strategy when founder get reward in $CLOUT
+$Coin->setStrategy('reward');
+
+// salamon bug fix strategy when founder always get reward in coins
+$Coin->setStrategy('minting');
+
+// Watermark is a initial strategy of BitClout blockchain, once supply reached no more reward minted for creator
+$Coin->setStrategy('watermark');
+
+// Or just set it with block height
+$Coin->setStrategyByHeight(1000);
+```
+
