I've installed the qt5-doc package but I'm not able to open the .qch files that I find in the /usr/share/qt5/doc/ directory.

Do you know how I can do this?

I've tried using qt5-assistant like this: assistant -collectionFile <help-file>.qhc but that didn't show anything.

To read pre-installed documentation you have to run Qt Assistant without arguments assistant and then select needed category from the Contents tab.

To open custom *.qch file you have to:

1. download it

   cd /tmp
   wget 

2. create new collection for it

   touch /tmp/my.qhc

3. register file in the new collection

   assistant -collectionFile /tmp/my.qhc -register /tmp/qwt-6.0.1.qch; 

4. open Qt Assistant with new collection

   assistant -collectionFile /tmp/my.qhc

   and navigate to the newly created entry in Contents (Qwt User's Guide 6.0.1 in my case).
