I followed sailfishos.wiki tutorial to install angelfish.
I have two remarks:
I suggest that sailfishos.wiki gets a page somewhere about : devel-su pkcon install zypper
Then I tried to add an environment variable in Qt Runner to switch Breeze into dark theme, but no luck so far…
Better solution here without zypper :
With same theming preoccupation.
New user, trawling information for the past 6 weeks and just found this thread.
This is a great idea! What is your current status with the App / Android App.
It will be very useful with my purchase of the ‘Jolla Phone (2026)’ 
Still work in progress, already has a good amount of relevant information but far from finished.
Really pleased you are still working on it. I know it will be a better way to educate new users, instead of them getting frustrated by not being able to quickly find what they need on this forum.
As was said above, this needs good visibility in the forum and Jolla documents.
The production of an android version is a solid idea. I am under no pressure to get the phone up and running, so decided against a learning platform phone. Therefore I have no access to sailfish apps and an Android version for myself and android users thinking about coming across to the platform would be a very useful insight.
Thanks for the reply and keep up the good work. The sooner it’s available, before the Jolla Phone (2026) hits the streets, the better. 
I have a User Guide made by Jolla. It is 67 pages. I printed it in 2014.
An app is common nowadays, yet a link to a web page would be fine also because this way you can search that site for solutions while practising on your phone.
