Drupal 8.x

I'm trying to install drupal 8 per the instructions on this website:

https://www.drupal.org/node/307956

I then get to the part on the above link where it says

"5. Browse to http://localhost/drupal/install.php and follow the instructions it gives. For the database information, use what you set up in step 3. See Getting started Run-script for more details."

Hi,
In content-type Article I have added an image-field as "multiple value".
For each image I get automatic an Alt-field and a Title-field.
But I need to add one extra field like a Taxonomy-field.

Example: I make an article for different places with images from these places. Then I can make a slideshow for each place.
But I would like to add an extra field to each image where I can choose like "Person", "View", "Museum", "Temple" etc.

Hi guys, Is there any module or way can do "Multiple nicknames on one single account" ?

For example, I create an account with ID "john987". And after logged in I can create 3 (or more) different nickname. Each nickname got their own User Info Page and other user dunno they are one same person except Admins.

When I post or reply to forum, I can choose which nickname I want as author. But I can only allow to use same one nickname on this very post.

All post by my nicknames, or by this ID, will add up so each nickname's User Info Page will show the same post count.

Hello,

Small explanation

:
I created a view 'user_category' which lists all users according to the taxonomic term 'category'. For example: administrator or developer.
I also created a module that displays the user's information with a link on the category text that refers to the 'user_categorie' view.

My question

:
We agree, if I remove the view, the module works less well.
How can I use the yml file of the view in the module, so that it recreates it automatically with each activation?
