+# Convert a Create React App project to a Modular Project
+
+To convert an existing [Create React App](https://create-react-app.dev/) project
+into a Modular app, start by creating a new Modular project as shown in the
+[getting started documentation](../index.md):
+
+`yarn create modular-react-app my-new-modular-project`
+
+Once created:
+
+- Replace the source code within the `app` workspace inside the `packages/`
+  directory with your React app source content.
+- Copy the dependencies from the old root package.json to the new Modular one
+  within the `app` workspace.
+  - Ensure the React version and other dependencies in the root Modular
+    package.json are the same as those used in the React app.
+- Copy over any necessary custom configurations, and ensure `modular start`
+  `test` and `build` scripts succesfully start, test and build your app.
+
+Your app will now be a Modular `app` package. You can change the package type in
+the package's package.json `modular.type` field to `view` if more appropriate.
+
+Feel free to rename the workspace by following this guide:
+[Rename Package](./rename-package).

+# Create a Modular Template
+
+To create a [Modular Template](../concepts/templates.md), start with any Modular
+package type for which you want to create a template for (`app`, `package`,
+etc). The package's contents will be copied into any new package created using
+the template.
+
+To convert the package into a template, make the following changes to the
+package's package.json:
+
+- Change `modular.type` field to `"template"`
+- Add `modular.templateType` with the desired target package type
+
+Example configuration for a template that generates `esm-view`s.
+
+```json
+{
+  "modular": {
+    "type": "template",
+    "templateType": "esm-view"
+  }
+}
+```
+
+Optionally, include a `files` array pattern containing any files that Modular
+should include from the template when creating a new package using it. Example:
+
+```json
+{
+  "files": [
+    "path/to/file-to-include-1.tsx",
+    "path/to/file-to-include-2.ts",
+    "folder-to-include"
+  ]
+}
+```
+
+If not specified, Modular will include all files.

+# Rename a Modular Package
+
+To rename a Modular package, find and replace the package name in the following
+places:
+
+- The `name` field in the package's package.json
+- All places where the package is imported/referenced
+
+Feel free to rename the package directory, although this will not have an impact
