+
+[Break](https://break.solana.com/) is a React app that gives users a visceral
+feeling for just how fast and high-performance the Solana network really is.
+Can you _break_ the Solana blockchain?
+During a 15 second playthough, each click of a button or keystroke
+sends a new transaction to the cluster.  Smash the keyboard as fast as you can
+and watch your transactions get finalized in real time while the network takes
+it all in stride!
+
+Break can be played on our Devnet, Testnet and Mainnet Beta networks.  Plays are
+free on Devnet and Testnet, where the session is funded by a network faucet.
+On Mainnet Beta, users pay to play 0.08 SOL per game.  The session account can
+be funded by a local keystore wallet or by scanning a QR code from Trust Wallet
+to transfer the tokens.

+First fetch the latest version of the example code:

+$ git clone https://github.com/solana-labs/break.git
+$ cd break

+
+Hello World is a project that demonstrates how to use the Solana Javascript API
+to build, deploy, and interact with programs on the Solana blockchain.
+
+The project comprises of:
+ - An on-chain hello world program
+ - A client that can send a "hello" to an account and get back the number of
+ times "hello" has been sent
+
+## Build and run Hello World program

+First fetch the latest version of the example code:
+
+```bash
+$ git clone https://github.com/solana-labs/example-helloworld.git
+$ cd example-helloworld

-[Click here to play Tic-Tac-Toe](https://solana-example-tictactoe.herokuapp.com/) on the Solana testnet. Open the link and wait for another player to join, or open the link in a second browser tab to play against yourself. You will see that every move a player makes stores a transaction on the ledger.

-## Getting lamports to users
-
-You may have noticed you interacted with the Solana cluster without first needing to acquire lamports to pay transaction fees. Under the hood, the web app creates a new ephemeral identity and sends a request to an off-chain service for a signed transaction authorizing a user to start a new game. The service is called a _drone_. When the app sends the signed transaction to the Solana cluster, the drone's lamports are spent to pay the transaction fee and start the game. In a real world app, the drone might request the user watch an ad or pass a CAPTCHA before signing over its lamports.
