This guide explains how to sync translations on Linux (Ubuntu 16.04 as reference). It is assumed that you have the Qt 5 framework up and running already.
If you've never done so, please run script https://bitbucket.org/heldercorreia/speedcrunch/raw/master/adm/install-intl-dependencies.sh and follow the instructions if shown.
If you don't have it yet, ask for admin permissions to your user account on SpeedCrunch Transifex page.
From this point on, all you should need to do is to run script https://bitbucket.org/heldercorreia/speedcrunch/raw/master/adm/sync-translations.sh every time you want to synchronize with Transifex.
