+## What is a libre currency?
+
+A [libre currency](https://libre-currency.org/) is a concept that originated from the [Relative Theory of Money](https://en.trm.creationmonetaire.info/).
+
+It is a way to design a currency so that every human, whatever the generation they are part of, produces the same relative amount of money.
+
+The Relative Theory of Money was written by a French mathematician in 2010, and the first libre currency (Ğ1) was born in 2017. Up to this day, Ğ1 is the only libre currency we know of.
+
+### Ğ1, the first libre currency
+
+Ğ1 the first libre currency we know of.
+
+It runs on [the Duniter blockchain engine](https://duniter.org/).
+
+The main clients for Duniter are [Cesium](https://cesium.app/) and [Silkaj](https://mystifying-nobel-66ae54.netlify.com/)
+
+## How to spend your Ğ1
+
+The Ğ1 currency originated in called [ğchange.fr](https://www.gchange.fr/#/app/home).
+
+The economy is still in its infancy, but you can already [book a reservation in a B&B](https://www.gchange.fr/#/app/market/lg?last&category=cat67&type=offer).
+
+An other way to spend your Ğ1 is use it with this micro-donation system.
+
+Run the install script and
