# Start
All elements of an app are included in a collection. A collection is a combination of app basics, dasboards, forms and datasets configured and extended with logic functions and navigation.
### **Start = create - select a collection**
After a new application has been [created](broken://pages/-Ma3NpGL2UP7fbuZiXIQ), or when you want to edit an existing application all modules of the app platform will only be available after the selection and **activation of a specific app collection**.
**Deleting a collection** is possible in the App Studio - Basics - Main toolbar
### Profile settings - Compact collection
You can enable a compact overview of the available collections in the menu part - Profile - Preferences - Studio settings - Compact collection
Selecting "Collections" next to your profile at the top right of the main bar opens the compact panel.
### User profile - log out
Log out from the App Studio on the **top right of the main bar** by pressing **sign out**.
### More collections in one app
In one (company) app as published in the stores or available on desktop (url) you can have a number of collection, each with his own authorized users and it's specific functionality.

## 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://academy.any2info.com/any2info-academy/no-code-platform/startcollection.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.
