+# Lumos & Omnilock Administrator mode
+
+Nervos maintains a powerful lock
+called [Omni Lock](https://github.com/XuJiandong/docs-bank/blob/master/omni_lock.md) (previously named RC lock), which
+can use private key as a signer. This example will show how to use Lumos to send a transaction using Omni lock Administrator mode
+
+## Quick Start
+
+```
+$ yarn
+$ yarn build
+```
+
+use lib
+```
+$ node --experimental-repl-await
+
+# import lib
+node> omni = require("./index")
+
+# generate white list sparse merkle tree root & proof
+node> { root, proof } = omni.generateWLRule([omni.alice.lockScript.args])
+
+# deploy white list cell with typeId
+node> rceCellScript = await omni.deployRCE({ from: omni.alice.address, fromPrivKey: omni.alice.privKey, root })
+
+# generate bob's omnilock administrator addr
+node> bobOmniAddr = omni.generateOmniLockAdministratorAddress(omni.bob.lockScript.args.substring(2), rceCellScript.CODE_HASH.substring(2))
+
+# get test CKB from https://faucet.nervos.org/
+
+# wait a moment, and we can find bob's omnilock administrator addr has test CKB
+
+# unlock by administrator (alice) pubkey hash
+node> txSkeleton = await omni.buildTransferByOmnilockAdministrator({
+  rceCellConfig: rceCellScript,
+  from: bobOmniAddr,
+  to: omni.alice.address,
+  amount: "10000000000",
+});
+
+node> signedTx = omni.sealOmnilockTxSkeleton(txSkeleton, omni.alice.privKey, omni.alice.lockScript.args, proof);
+
+node> txHash = await omni.rpc.send_transaction(signedTx, "passthrough");
