# Adding a New Sample to the Library
This option allows the user to add a new artifact to the Platform. To add a new sample to the library, follow the steps below:
1. In the Threat Library tab select the "New Artifact" button at the top right.
2. A form will open. Fill in all the fields with the information related to the sample.
* Platform: Here the user select the type of operating system for which the sample is intended (Windows or Linux).
Ext. Allowed
When selecting this option, there is a "choose file" section where the user will have to choose which artifact to add to the Platform.
Artifact Report
If the user have any document with more extensive or specific information about the artifact, it will be added at this point, in PDF format.
Severity
Here the user select the threat level of the artifact to be added (Critical, High, Low, Midd, None, Zero-Day).
MITRE ATT\&CK Tactics
Mitre's tactics and techniques, used in the specific artifact, are selected, which are a set of techniques used by the adversaries to achieve a specific aim. For more information see .
Description
Here the description of the artifact is assigned, i.e., what type of malware it is, what its malicious, suspicious, and informative behaviors are.
Show Options
Selecting this function will enable more advanced options for the sample.
* ATT\&CK Navigator URL: Here we can attach the MITRE link of the artifact.
* Callback: This option is selected if the artifact or sample can send the callback to the remote server attack.
* Force Network Cybersecurity: In this option the "manifests" of the encrypted artifacts are added.
Show Resolution Actions
By selecting this function, we can add more artifact information, the network, Endpoint, and Callback resolution actions are added, which for artifacts loaded by EVE includes information such as their hashes or flags, string-based YARA Rule, and MITRE-based mitigations. Note that the user can add the own resolution actions to the samples the user load.
3. Click on to save and load the sample to the library. The sample is now available for testing and/or emulation.

## 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://docs.reveald.com/technical-documentation/admin-guides/epiphany-validation-engine-users-guide/chapter-3-eve-platform/navigation-tabs/emulation-control/threat-library/adding-a-new-sample-to-the-library.md?ask=&goal=
```
`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.
