 # Agoric Dapp Starter: Agoric Basics
 
 This is a basic Agoric Dapp that contains three smart contracts `postal-service`, `sell-concert-tickets`, and `swaparoo` demonstrating different scenarios which can be implemented easily using Agoric SDK. There is also a UI for `sell-concert-tickets` contract that a user can use to buy three different types of concert tickets and pay through a wallet extension in the browser. 
+The following instrucions provide a guide to setup an environment to try `dapp-agoric-basics` on your local machine. If you want to try it in cloud environment without any installations or downloads, you can [try it in github codespaces](#instructions-to-run-dapp-agoric-basic-in-ghcs).

+## Instructions to run `dapp-agoric-basic` in GHCS
+
+Here are the step-by-step instructions to run/work on `dapp-agoric-basic` in github codespaces:
+
+1. Go to repo here: [https://github.com/Agoric/dapp-agoric-basics/](https://github.com/Agoric/dapp-agoric-basics/)
+2. Click on ![Green `<> Code` button](https://docs.github.com/assets/cb-13128/mw-1440/images/help/repository/code-button.webp)
+3. Click on `Codespaces` tab and create a new Codespace. If you are already using Codespaces on current repo then click the "+" button on top right of the `Codespaces` tab to create a new one.
+4. You should see a VSCode environment load in your browser followed by a setup. This should take a few minutes.
+5. Once it's done do `yarn install` in the terminal.
+6. Do `yarn start:docker` followed by `yarn docker:logs` - kill it after you see `begin`/`commit`.
+7.  Do `yarn start:contract`.
+8. Do `yarn start:ui` - a pop-up should appear in bottom right. Click open in browser if needed.
+9. DApp should be load in your browser.
+10. Connect your Wallet and interact with DApp as usual.
