+`npm install --save @getsafle/vault-bevm-controller`
+
+## Initialize the BEVM Controller class
+
+```
+const { KeyringController, getBalance } = require('@getsafle/vault-bevm-controller');
+
+const bevmController = new KeyringController({
+  encryptor: {
+    // An optional object for defining encryption schemes:
+    // Defaults to Browser-native SubtleCrypto.
+    encrypt(password, object) {
+      return new Promise('encrypted!');
+    },
+    decrypt(password, encryptedString) {
+      return new Promise({ foo: 'bar' });
+    },
+  },
+});
+```
+
+## Methods
+
+### Generate Keyring with 1 account and encrypt
+
+```
+const keyringState = await bevmController.createNewVaultAndKeychain(password);
+```
+
+### Restore a keyring with the first account using a mnemonic
+
+```
+const keyringState = await bevmController.createNewVaultAndRestore(password, mnemonic);
+```
+
+### Add a new account to the keyring object
+
+```
+const keyringState = await bevmController.addNewAccount(keyringObject);
+```
+
+### Export the private key of an address present in the keyring
+
+```
+const privateKey = await bevmController.exportAccount(address);
+```
+
+### Sign a transaction
+
+```
+const signedTx = await bevmController.signTransaction(bevmTx, _fromAddress);
+```
+
+### Sign a message
+
+```
+const signedMsg = await bevmController.signMessage(msgParams);
+```
+
+### Sign a message
+
+```
+const signedObj = await bevmController.sign(msgParams, pvtKey, web3Obj);
+```
+
+### Sign Typed Data (EIP-712)
+
+```
+const signedData = await bevmController.signTypedMessage(msgParams);
+```
+
+### Get balance
+
+```
+const balance = await bevmController.getBalance(address, web3);
+```
+
+### Send Transaction
+
+```
+const receipt = await bevmController.sendTransaction(signedTx, web3);
+```
+
+### Calculate Tx Fees
+
+```
+const fees = await bevmController.getFees(rawTx, web3);
