# First Step: Installing S-Sign

## S-Sign Quick Install Guide: Salesforce Lightning

This guide provides a step-by-step walkthrough for installing and configuring S-Sign, a 100% native e-signature solution for Salesforce.

***

### Phase 1: Installation

Unlike S-Docs, S-Sign is not available on the AppExchange. To install S-Sign:

1. Request Link: Contact [**S-Docs Sales**](https://www.sdocs.com/about?qgad=703925338752\&qgterm=s-docs\&gad_source=1\&gad_campaignid=21410070609\&gbraid=0AAAAADBYf9M1VfW8vCUAWRql9uBDlauQm\&gclid=Cj0KCQjwkYLPBhC3ARIsAIyHi3RenceVMoyo3g4ObZ837vOb6Fs4hHTibU0llZAvHIQDl9J3B40IJVcaAsW7EALw_wcB#contact-us\&utm_campaign=AVA-Brand\&utm_source=adwords\&utm_medium=ppc\&utm_term=s-docs\&hsa_kw=s-docs\&hsa_net=adwords\&hsa_grp=165564168842\&hsa_cam=21410070609\&hsa_acc=6588399060\&hsa_tgt=kwd-940841427764\&hsa_ver=3\&hsa_ad=703925338752\&hsa_mt=e\&hsa_src=g) to obtain the latest installation link.
2. Installation Type: Select **Install for Admins Only**.
3. Environment: It is highly recommended to setup and test in a Sandbox before installing in Production.
4. Verification: Navigate to **Setup > Installed Packages** to ensure S-Sign and S-Docs version numbers are up to date.
5. Permissions: Assign either the **S-Sign User** or **S-Sign Administrator** permission set to yourself and relevant users.

{% hint style="info" %}
**Major Package Versions for S-Docs and S-Sign must align to ensure proper functionality.** Please contact your Customer Success Manager or S-Docs Support to request patch links corresponding to your organization's current version.
{% endhint %}

## 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://help.sdocs.com/quick-start/s-sign-setup/first-step-installing-s-sign.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.
