 This is a simple devcontainer which can be used with CodeSpaces or VSCode Remote to get all the tooling needed to start authoring bicep. 
 
 ## Quick Start: VSCode Remote
-
 1. Clone the repository.
-1. Configuration for the development environment by installing VSCode and the Devcontainers extension. [Quick start docs here](https://code.visualstudio.com/docs/remote/containers-tutorial).
-1. Open the folder in VSCode
-devcontain1. [`CTRL+SHIFT+P` then type `Reopen in container`](https://code.visualstudio.com/docs/remote/containers#_getting-started) to open the devcontainer in VSCode.
+1. Configure the development environment by installing VSCode and the "Remote - Containers" extension. [Quick start docs here](https://code.visualstudio.com/docs/remote/containers-tutorial).
+1. Open the repository in VSCode
+1. [`CTRL+SHIFT+P` then type `Reopen in container`](https://code.visualstudio.com/docs/remote/containers#_getting-started) to open the devcontainer in VSCode.
 1. [Open a terminal in VSCode with `CTRL+SHIFT+P` -> `Terminal: Create new integrated terminal`](https://code.visualstudio.com/docs/remote/containers#_opening-a-terminal). We'll use this to run Bicep commands.
 1. [Run `az login`](https://docs.microsoft.com/en-us/cli/azure/authenticate-azure-cli) from the VSCode terminal to connect to your Azure account.
-1. Run `bicep build main.bicep` this will generate `main.json` which is the ARM template ready to be deployed.
-1. Run the following to create a resource group and deploy the template to it.
-```
-	az group create -n my-rg -l eastus
-	az deployment group create -f ./main.json -g my-rg
-```
+1. Run the following to create a resource group and deploy your Bicep file to it.
+    ```sh
+    az group create -n my-rg -l eastus
+    az deployment group create -f ./main.bicep -g my-rg
+    ```
+1. Open [main.bicep](./main.bicep) in to modify the resources you want to deploy, and re-run the `az deployment group` command to re-deploy the resources.
+
+## Quick Start: Codespaces
+1. Open this repository in [GitHub Codespaces](https://github.com/features/codespaces).
+1. Open a terminal in VSCode with `CTRL+J`. We'll use this to run Bicep commands.
+1. [Run `az login`](https://docs.microsoft.com/en-us/cli/azure/authenticate-azure-cli) from the VSCode terminal to connect to your Azure account.
+1. Run the following to create a resource group and deploy your Bicep file to it.
+    ```sh
+    az group create -n my-rg -l eastus
+    az deployment group create -f ./main.bicep -g my-rg
+    ```
+1. Open [main.bicep](./main.bicep) in your Codespaces window to modify the resources you want to deploy, and re-run the `az deployment group` command to re-deploy the resources.
 
 ## Next Steps
 
-Review [the docs here](https://github.com/Azure/bicep) to build out more advanced scenarios.
+Review [the Bicep documentation](https://docs.microsoft.com/en-us/azure/azure-resource-manager/bicep/overview) to build out more advanced scenarios.
 
-## Configuration 
-
-To target a specific release of Bicep update the `./devcontainer/Dockerfile` argument `ARG BICEP_VERSION=latest` to the required version.
