# Upload a StackPack file

The `.sts` file is a zip archive that contains the [StackPack file structure](/5.1/develop/developer-guides/stackpack/prepare_package.md). When all files are in place, archive your StackPack directory into a `.zip` file and change its extension to `.sts`.

To upload the `.sts` file to StackState use the [StackState CLI](/5.1/setup/cli.md) with the following command: \`

{% tabs %}
{% tab title="CLI: sts" %}

```
sts stackpack upload --file <PATH_TO_FILE.sts>
```

From StackState v5.0, the old `sts` CLI has been renamed to `stac` and there is a new `sts` CLI. The command(s) provided here are for use with the new `sts` CLI.

➡️ [Check which version of the `sts` CLI you are running](/5.1/setup/cli/cli-comparison.md#which-version-of-the-cli-am-i-running)
{% endtab %}

{% tab title="CLI: stac (deprecated)" %}

```
stac stackpack upload <PATH_TO_FILE.sts>
```

⚠️ **From StackState v5.0, the old `sts` CLI is called `stac`. The old CLI is now deprecated.**

The new `sts` CLI replaces the `stac` CLI. It's advised to install the new `sts` CLI and upgrade any installed instance of the old `sts` CLI to `stac`. For details see:

* [Which version of the `sts` CLI am I running?](/5.1/setup/cli/cli-comparison.md#which-version-of-the-cli-am-i-running)
* [Install the new `sts` CLI and upgrade the old `sts` CLI to `stac`](/5.1/setup/cli/cli-sts.md#install-the-new-sts-cli)

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://archivedocs.stackstate.com/5.1/develop/developer-guides/stackpack/how_to_pack_and_upload_stackpack.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
