+## How do I run the `sv` CLI?
+
+Running the `sv` cli differs for each package manager. Here is a list of the most common commands:
+
+- **NPM** : `npx sv create`
+- **PNPM** : `pnpx sv create` or `pnpm dlx sv create`
+- **Yarn** : `yarn dlx sv create`
+- **Bun** : `bunx sv create`
+- **Deno** : `deno run npm:sv create`
+
+## `npx sv` is not working
+
+Some package mangers prefer to run locally installed tools instead of downloading and executing packages from the registry. This issue mostly occurs with `npm` and `yarn`. This usually results in an error message or looks like the command you were trying to execute did not do anything.
+
+Here is a list of issues with possible solutions that users have encountered in the past:
+
+- [`npx sv` create does nothing](https://github.com/sveltejs/cli/issues/472)
+- [`sv` command name collides with `runit`](https://github.com/sveltejs/cli/issues/259)
+- [`sv` in windows powershell conflicts with `Set-Variable`](https://github.com/sveltejs/cli/issues/317)
