# Extend a MapSet
Docs on how to merge more maps into an existing MapSet
### 1. Go into the MultiSet App and choose a MapSet to extend
Select the "Extend MapSet" option from the below screen and follow a similar process of selecting a new map that needs to be merged into the existing MapSet
### 2. Localize into any map of the existing Mapset, then localize the new map
To add a new map, just localize to any existing map of Mapset, then walk to the new map that needs to be added and localize.
{% hint style="warning" %}
Ideally, localize the closest map in the existing Mapset to the new map that's being added to reduce the walking distance and to reduce merging errors
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.multiset.ai/fundamentals/mapset-multiple-maps/merging-maps-without-overlap/extend-a-mapset.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
