+---
+
+# Create Redwood App
+
+To get up and running with Redwood, you can use Create Redwood App:
+
+```terminal
+yarn create redwood-app <your-app-name>
+```
+
+## Set up for success
+Redwood requires that you're running Node version 18.0.0 or higher.
+
+If you're running Node version 19.0.0 or higher, you can still use Create Redwood App, but it may make your project incompatible with some deploy targets, such as AWS Lambdas.
+
+To see what version of Node you're running, you can run the following command in your terminal:
+
+```terminal
+node -v
+```
+
+If you need to update your version of Node or run multiple versions of Node, we recommend installing nvm and have [documentation about how to get up and running.](/docs/how-to/using-nvm)
+
+You also need to have yarn version 1.15 or higher installed. To see what version of yarn you're running, you can run the following command in your terminal:
+
+```terminal
+yarn -v
+```
+
+To upgrade your version of yarn, [you can refer to the yarn documentation](https://yarnpkg.com/getting-started/install).
+
+## What you can expect
+
+### Select your preferred language
+Options: TypeScript (default) or JavaScript
+
+If you choose JavaScript, you can always [add TypeScript later](/docs/typescript/introduction#converting-a-javascript-project-to-typescript).
+
+### Do you want to initialize a git repo?
+Options: yes (default) or no
+
+If you mark "yes", then it will ask you to **Enter a commit message**. The default is message is "Initial commit."
+
+You can always initialize a git repo later and add a commit message by running the following commands in your terminal:
+
+```terminal
+git init
+git add .
+git commit -m "Initial commit"
+```

+
+### Do you want to run `yarn install`?
+Options: yes (default) or no
+
+_NOTE: This prompt will only display if you're running yarn, version 1._
+
+This command will download all of your project's dependencies.
+
+If you mark "no", you can always run this command later:
+
+```terminal
+cd <your-app-name>
+yarn install
+```
+
+## Running the development server
+
+Once the Create Redwood app has finished running, you can start your development server by running the following command:
+
+```terminal
+cd <your-app-name>
+yarn install
+yarn rw dev
+```
+
+- This will start your development server at `http://localhost:8910`.
+- Your API will be available at `http://localhost:8911`.
+- You can visit the Redwood GraphQL Playground at `http://localhost:8911/graphql`.
+
+## Flags
+You can by pass these prompts by using the following flags:
+
+| Flag | Alias | What it does |
+| :--- | :--- | :--- |
+| `--yarn-install` | | Run `yarn install` |
+| `--typescript` | `ts` | Set TypeScript as the preferred language (default to JavaScript) |
+| `--overwrite` | | Overwrites the existing directory, if it has the same name |
+| `--git-init` | `git` | Initializes a git repository |
+| `--commit-message "Initial commit"` | `m` | Specifies the initial git commit message |
+
+For example, here's the project with all flags enabled:
+
+```terminal
+yarn create redwood-app <your-app-name> --typescript --git-init --commit-message "Initial commit" --yarn-install
+```
+
