# Packages
# @extends
You can publish libraries (also known as packages or extensions)
that users can then add to their scripts. These typically
provide a driver for a particular hardware device you can connect
to a microbit.
## #approval
### ~ hint
All packages need to be approved by the Micro:bit Foundation before being available in the web editor.
See **Approval** section below.
Contact the Microbit Foundation support to get your package approved.

## Finding packages
From the block editor, the user clicks on **Add Package** and searches for the package.
Otherwise, the **Add Package** is also available from the gearwheel menu.
To see the list of packages, switch to JavaScript and use the **Explorer** view to find them.
To remove a package, click on the garbage button in the **Explorer** view next to the package.
## Publishing and Approving packages
Once your package is ready, follow these steps to get it approved and listed in the pxt.microbit.org web site:
1. setup a public GitHub repository with your package sources
2. ensure that the license is **Apache2** or **MIT**
3. fill ``test.ts`` with a test scenario
4. ensure that the package builds by running ``pxt`` from the package folder. [Read more...](https://www.pxt.io/packages).
5. fill up the ``README.md`` file with documentation. See [markdown docs](https://pxt.io/writing-docs) for syntax.
6. publish a release by running ``pxt bump`` from the package folder.
7. open a support ticket at https://support.microbit.org, add **package approval** in the subject line.

## Localizing packages
It is possible to package localization strings for the **jsDoc** description associated to the API in the package.
When compiling a package, the PXT compiler generates a `strings.json` file under the `_locales/` folder.
This file contains a map from the symbol name to the en
```
{
...
"basic": "Provides access to common functionality.",
...
}
```
```
{
"basic.clearScreen": "Eteint toutes les diodes."
}
```
```
