+# Stellar Client
+
+This Dart client allows you to communicate with the Stellar network, enabling the creation or loading of existing Stellar accounts. It supports interactions with both the testnet and public network, and the assets currently supported are TFT (Threefold Token) and XLM (Stellar Lumens).
+
+## Installation
+
+To install the necessary dependencies, run:
+
+```bash
+dart pub get
+```
+
+## Usage
+
+This client enables you to create new Stellar accounts or load existing ones on the testnet or public network. Once an account is created or loaded, you can manage assets such as TFT and XLM.
+
+### TESTNET
+
+Create new testnet account:
+
+- If no mnemonic provided, it will be created by the client.
+- By default the account activated by threefold activation service, will contains both assets TFT and XLM.
+
+```dart
+  import 'package:stellar_client/stellar_client.dart';
+
+  final stellarClient = Client(NetworkType.TESTNET);
+  final keypair = stellarClient.createThreefoldAccount(mnemonic: "");
+  final balance = await stellarClient.getBalance();
+  print(balance);
+
+  await stellarClient.getTransactions();
+```
+
+Load previously created account:
+
+- Accounts can be loaded from public key or secret seed.
+- If user wants to make any transactions, account should be loaded from secret seed.
+
+```dart
+  import 'package:stellar_client/stellar_client.dart';
+
+  final stellarClient = Client(NetworkType.TESTNET);
+  final account = stellarClient.loadAccountFromPublicKey(accountId: "account_id");
+```  
+
+### PUBLIC
+
+```dart
+  import 'package:stellar_client/stellar_client.dart';
+
+  final stellarClient = Client(NetworkType.PUBLIC);
+  final keypair = stellarClient.createThreefoldAccount(mnemonic: "");
+  await stellarClient.sendTransaction(
+      sourceKeyPair: account,
+      destinationAddress:
+          "destination-public-key",
+      amount: "20",
+      currency: "TFT",
+      memoText: "Memo Text");
+
+  await stellarClient.getTransactions();
+```
