# Memory

Any good chatbot probably needs to be able to save and work with information gathered from the user at some point. The memory API provided in CSML is one of the most important parts of the language.

As you will see, some variables need to be stored in a long-term memory, while some variables are just temporary variables needed for local work. Some information is also provided by the context of the user and injected by the channel itself at the beginning of the conversation.

In this chapter, we will see how to save and use various types of memories depending on your scenario.

## 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.csml.dev/language/memory.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.
