+Extracts project creation functionality from `preact-cli` into `create-preact-cli`
+
+Setting up new `preact-cli` projects with `npx` is slow, as all dependencies of `preact-cli` would need to be installed, even though only a handful are used for project initialization. On the other hand, suggesting global installs is less than attractive due to NPM's poor default install location (requires `sudo`) and this can get out of sync over time.
+
+By extracting project initialization into its own package, we can provide much, much faster project setup times.
+
+To setup a new project, users will use `npm init preact-cli ...` or `yarn create preact-cli ...`.
+
+Additionally, the `--yarn` flag has been removed in favour of using the yarn initializer (`yarn create`).

 The purpose of official preact project templates are to provide opinionated development tooling setups so that users can get started with actual app code as fast as possible. However, these templates are un-opinionated in terms of how you structure your app code and what libraries you use in addition to preact.js.
 
-All official project templates are repos in the [preactjs-templates organization]. When a new template is added to the organization, you will be able to run `npx preact-cli create <template-name> <project-name>` to use that template.
