 # Rust SDK examples
 
-Examples of interacting with the move contract using the Sui Rust SDK.
+This directory contains examples of interacting with a Move language smart contract using the Sui Rust SDK. See the [introduction to the Rust SDK](https://github.com/MystenLabs/sui/blob/main/doc/src/build/rust-sdk.md) for additional details.
 
 ## Tic Tac Toe
 
 ### Demo quick start
 
 #### 1. Prepare the environment 
-   * Install `sui` and `rpc-server` binaries following the [installation doc](https://github.com/MystenLabs/sui/blob/main/doc/src/build/install.md#binaries).
-   * [Connect to devnet](https://github.com/MystenLabs/sui/blob/main/doc/src/build/cli-client.md#connect-to-devnet).
-   * Make sure you have two addresses with gas, you can use the new-address command to create new addresses `sui client new-address`, 
-   you can skip this step if you are going to play with a friend :)
-   * [Request gas tokens](https://github.com/MystenLabs/sui/blob/main/doc/src/explore/devnet.md#request-gas-tokens) for all addresses that will be used to join the game.
+   1. Install `sui` and `rpc-server` binaries following the [Sui installation](https://github.com/MystenLabs/sui/blob/main/doc/src/build/install.md#binaries) docs.
+   1. [Connect to Sui Devnet](https://github.com/MystenLabs/sui/blob/main/doc/src/build/cli-client.md#connect-to-devnet).
+   1. [Make sure you have two addresses with gas](https://github.com/MystenLabs/sui/blob/main/doc/src/build/cli-client.md#adding-accounts-to-the-client) by using the `new-address` command to create new addresses:
+      ```shell
+      sui client new-address
+      ```
+      You can skip this step if you are going to play with a friend. :)
+   1. [Request Sui tokens](https://github.com/MystenLabs/sui/blob/main/doc/src/build/install.md#sui-tokens) for all addresses that will be used to join the game.
 
 #### 2. Publish the move contract
-   * [Download the Sui source code](https://github.com/MystenLabs/sui/blob/main/doc/src/build/install.md#source-code)
-   * Publish the [`games` package](https://github.com/MystenLabs/sui/tree/main/sui_programmability/examples/games) 
-      using the Sui client and copy down the package object ID.
+   1. [Download the Sui source code](https://github.com/MystenLabs/sui/blob/main/doc/src/build/install.md#source-code).
+   1. Publish the [`games` package](https://github.com/MystenLabs/sui/tree/main/sui_programmability/examples/games) 
+      using the Sui client:
       ```shell
       sui client publish --path /path-to-sui-source-code/sui_programmability/examples/games --gas-budget 10000
       ```
+   1. Record the package object ID.
 #### 3. Create a new tic-tac-toe game
-   * run the following command in the sui source code folder to start a new game.
+   1. Run the following command in the Sui source code directory to start a new game, replacing the game package objects ID with the one you recorded:
       ```shell
       cargo run --example tic-tac-toe -- --game-package-id <<games package object ID>> new-game
       ```
-        this will create a game for the first two addresses in your keystore by default. If you want to specify the identity of each player, 
-you can use the following command
+        This will create a game for the first two addresses in your keystore by default. If you want to specify the identity of each player, 
+use the following command and replace the variables with the actual player's addresses:
       ```shell
       cargo run --example tic-tac-toe -- --game-package-id <<games package object ID>> new-game --player-x <<player X address>> --player-o <<player O address>>
       ```
-   * Copy the game id and pass it to your friend to join the game.
+   1. Copy the game ID and pass it to your friend to join the game.
 #### 4. Joining the game
-   * run the following command in the sui source code folder to join the game.
-      ```shell
-      cargo run --example tic-tac-toe -- --game-package-id <<games package object ID>> join-game --my-identity <<address>> --game-id <<game ID>>
-      ```
+Run the following command in the Sui source code directory to join the game, replacing the game ID and address accordingly:
+```shell
+cargo run --example tic-tac-toe -- --game-package-id <<games package object ID>> join-game --my-identity <<address>> --game-id <<game ID>>
+```
