# 16.1: Setting Up Libwally
> **NOTE:** This is a draft in progress, so that I can get some feedback from early reviewers. It is not yet ready for learning.
This first section will explain how to download Libwally and how to get it working.
> :book: ***What is Libwally?*** Libwally is a library of primitives helpful for the creation of wallets that is cross-platform and cross-language, so that the same functions can be used everywhere. There are [extensive docs](https://wally.readthedocs.io/en/release_0.7.8/). It's made available as part of Blockstream's [Elements Project](https://github.com/ElementsProject).
## Installing Libwally
As usual, you'll need some packages on your system:
```
$ sudo apt-get install git
$ sudo apt-get install dh-autoreconf
```
You can download Libwally from its Git repo:
```
$ git clone https://github.com/ElementsProject/libwally-core
```
You can then get things installed:
```
$ ./tools/autogen.sh
```
As with `libbitcoinrpc`, you may wish to install this in `/usr/include` and `/usr/lib` for ease of usage. Just modify the appropriate line in the `configure` program:
```
< ac_default_prefix=/usr
---
> ac_default_prefix=/usr/local
```
Afterward you can finish your prep:
```
$ ./configure
$ make
```
You can then verify that tests are work:
```
$ make check
