+# Docker file for building Overte Qt5 packages for Ubuntu 18.04
+
+# Some steps for actually using this:
+# - Check which commit you are building https://invent.kde.org/qt/qt/qt5/-/tree/kde/5.15
+# - Adjust this file to include the commit hash you are building, the date, the number of threads you want to use (-j10), and the Qt and QtWebEngine versions.
+#     Keep in mind that building Qt requires a lot of memory. You should have over 1.2GiB of system memory available per thread.
+# - Run the build process with something like `PROGRESS_NO_TRUNC=1 DOCKER_BUILDKIT=1 BUILDKIT_STEP_LOG_MAX_SIZE=-1 docker build --progress plain -t overte-qt5:5.15.5-2022.07.13-kde_ea4efc067b47c11b1aac61668afd8578a6834f5b -f Dockerfile_Ubuntu_18.04_Qt5 .`
+#     Buildkit is used to cache intermittent steps in case you need to modify something afterwards.
+# - Once the build has completed, create a container from the image and export the created Qt package.
+#     `docker create --name extract overte-qt5:5.15.5-2022.07.13-kde_ea4efc067b47c11b1aac61668afd8578a6834f5b`

 On Ubuntu based systems you can just have apt install the dependencies for the qt5-default package:
 Edit /etc/apt/sources.list (edit as root) and uncomment all source repositories by replacing all `# deb-src` with `deb-src`.
