+# @dhis2/create-app
+
+This package publishes a package that follows the convention of [npm create](https://docs.npmjs.com/cli/v11/commands/npm-init#synopsis).
+
+This allows users to create a new DHIS2 web application by running the command:
+
+```sh
+# with pnpm
+pnpm create @dhis2/app project-name --yes
+#
+```
+
+```sh
+# with npm
+npm create @dhis2/app -- --yes
+# or npx @dhis2/create-app --yes
+```
+
+By passing `--yes` argument, this will create a new DHIS2 web application using the default options without prompting (using `pnpm` as a package manager, and `TypeScript` as the language).
+
+If you omit the `--yes` argument `pnpm create @dhis2/app project-name` then you will be prompted and guided through a wizard to choose your options.
+
+You can run the commands in `debug` mode to get more verbose logs by passing the `--debug` option (`pnpm create @dhis2/app project-name --debug`).
