 + Use `build.py` script which will build all Jami (daemon/client lib/client-qt)
 + Build only this client.
 
+## Disclaimer
+
+Because the client-qt is multi-platforms and supporting macOS, we need a recent version of Qt to do rendering with Metal. So, Qt 6.2 is necessary.
+This version is generally not packaged on a lot of platforms, and to control available plugins and such, we have our own Qt packaged (generated by https://review.jami.net/jami-project and available on https://jami.net on the distributions we support).
+So, you will need to get Qt 6.2 first. For this, there is 3 methods:
+
+### Qt from https://jami.net (recommended)
+
+If your distribution is supported, we provide a Qt package (`libqt-jami`) on our repo. Follow instructions https://jami.net/download-jami-linux/ (but instead installing `jami` install `libqt-jami`).
+The files will be installed in `/usr/lib/libqt-jami`.

+### Qt from your distribution
