 Sui allows a set of distributed authorities, some of which are Byzantine, to maintain a high-integrity and availability settlement system for pre-funded payments. It can be used to settle payments in a native unit of value (crypto-currency), or as a financial side-infrastructure to support retail payments in fiat currencies. Sui is based on Byzantine Consistent Broadcast as its core primitive, foregoing the expenses of full atomic commit channels (consensus). The resulting system has low-latency for both confirmation and payment finality. Remarkably, each authority can be sharded across many machines to allow unbounded horizontal scalability. Our experiments demonstrate intra-continental confirmation latency of less than 100ms, making Sui applicable to point of sale payments. In laboratory environments, we achieve over 80,000 transactions per second with 20 authorities---surpassing the requirements of current retail card payment networks, while significantly increasing their robustness.
 
+## Quickstart with local Sui network and interactive wallet
+### 1. Build the binaries
+```shell
+cargo build --release
+cd target/release
+```
+This will create `fastx` and `wallet` binaries in `target/release` directory. 
+
+### 2. Genesis
+```shell
+./fastx genesis
+```
+The genesis command creates 4 authorities, 5 user accounts each with 5 gas objects.
+The network configuration are stored in `network.conf` and can be used subsequently to start the network.  
+A `wallet.conf` will also be generated to be used by the `wallet` binary to manage the newly created accounts.
+
+### 3. Starting the network
+Run the following command to start the local Sui network: 
+```shell
+./fastx start 
+```
+or 
+```shell
+./fastx start --config [config file path]
+```
+The network config file path is defaulted to `./network.conf` if not specified.  
+
+### 4. Running interactive wallet
+To start the interactive wallet:
+```shell
+./wallet
+```
+or
+```shell
+./wallet --config [config file path]
+```
+The wallet config file path is defaulted to `./wallet.conf` if not specified.  
+
+The following commands are supported by the interactive wallet:
+
+    addresses      Obtain the Account Addresses managed by the wallet
+    call           Call Move
+    help           Prints this message or the help of the given subcommand(s)
+    new-address    Generate new address and keypair
+    object         Get obj info
+    objects        Obtain all objects owned by the account address
+    publish        Publish Move modules
+    sync           Synchronize client state with authorities
+    transfer       Transfer funds
+
+Use `help <command>` to see more information on each command.
+
+### 5. Using the wallet without interactive shell
+The wallet can also be use without the interactive shell
+```shell
+USAGE:
+    wallet --no-shell [SUBCOMMAND]
+```
+#### Example
+```shell
+sui@MystenLab release % ./wallet --no-shell addresses
