+## I. Telegram Mini Apps
+
+We have built a [Telegram Mini Apps](https://core.telegram.org/bots/webapps) for users to directly upload and store files to TONBags in telegram.
+
+1. In telegram, search and add TonBagsBot(Test)

+
+2. Use '/connect' command to connect to your TON wallet
+
+   ![Pic](assets/build/tonbags-miniapp-connect.png)
+
+3. Select and upload some files. Confirm the transaction on the connected TON wallet.
+
+4. Use '/my_files' command to launch the Mini Apps.

 ## II. Storage smart contract
 
-- Testnet storage contract address: https://testnet.tonviewer.com/kQBOOMNqG0rvNm6vFGfR4qZl48BTDw_gYefVI4DQ70t9GjhI
+- Testnet storage contract address: https://testnet.tonviewer.com/EQBOOMNqG0rvNm6vFGfR4qZl48BTDw_gYefVI4DQ70t9GoPC
 - Mainnet storage contract address: (coming soon)
 
-## III. Example (coming soon)
+## III. SDK & Example
+
+Developers could use [tonbags-sdk](https://www.npmjs.com/package/@crustnetwork/tonbags-sdk) to place storage orders.
+
+**Installation**
+
+```sh
+$ npm install @crustnetwork/tonbags-sdk @ton/ton @ton/core @ton/crypto
+```
+
+**Usage**
+
+```javascript
+import tonbagssdk from '@crustnetwork/tonbags-sdk'
+import { default_storage_period } from "@crustnetwork/tonbags-sdk/src/TonBags";
+import { Address, toNano } from "@ton/core";
+import { mnemonicToPrivateKey } from "@ton/crypto";
+import { TonClient, WalletContractV4 } from "@ton/ton";
+
+const tc = new TonClient({
+    endpoint: "https://testnet.toncenter.com/api/v2/jsonRPC",
+});
+const tonbagsAddress = Address.parse(
+    "EQBOOMNqG0rvNm6vFGfR4qZl48BTDw_gYefVI4DQ70t9GoPC"
+);
+const tonBags = tonbagssdk.TonBags.createFromAddress(tonbagsAddress);
+
+const openTonBags = tc.open(tonBags);
+const keyPair = await mnemonicToPrivateKey(["your", "mnemonic"]);
+const wallet = tc.open(
+    WalletContractV4.create({ workchain: 0, publicKey: keyPair.publicKey })
+);
+await openTonBags.sendPlaceStorageOrder(
+    wallet.sender(keyPair.secretKey),
+    tonrrentHash, // torrentHash or bagId
+    1024n, // fileSize
+    merkleHash, // file merkle tree root hash
+    toNano("0.1"), // storageFee
+    default_storage_period // storage period time
+);
+```
+
+Before placing order, the file need be encoded into a merkle tree, and the root hash need be passed to TONBag storage contract. Below is the code example:
+
+```javascript
+import { merkle } from '@crustnetwork/tonbags-sdk'
+
+const readAsBlob = async (file: string) => {
+  return new Promise<Blob>((resolve, reject) => {
+    let chunks: Buffer[] = [];
+    fs.createReadStream(file)
+      .on("error", reject)
+      .on("data", (data: Buffer) => {
+        chunks.push(data);
+      })
+      .on("end", () => resolve(new Blob(chunks)));
+  });
+};
+
+const mt = new merkle.MerkleTree();
+const blob = await readAsBlob("test.txt");
+// generate merkle tree
+await mt.genTree(blob);
+// merkle tree root
+const merkleRoot = mt.tree![0];
+```
