==page creation==
'''How to create a page?'''

In a wiki the information is organized into pages or articles ( no great distinction between the two). If you want to say something about something for which there isn't a page, you create that page and start writing its content. 

To create a page  use the '''chain icon''' on the menu, as wiki page are essentially '''internal links'''. The result will be:
<nowiki>[[name of new page]]</nowiki> .

You can now save you page and see that the link that you created to the new page is <span style="color:red">red</span>.
* <span style="color:red">Red</span> link = previously non-existing page. 
* <span style="color:blue">Blue</span> link = existing page.

[[Grafiwiki]] - an existing page

==external links==
To link to external webpages, use the '''world icon'''.

You'll be presented with:
<nowiki>[http://www.example.com link title]</nowiki> and simply need to replace them with url and title(optional)

like:

<nowiki>[http://beyond-social.org/ Beyond Social] </nowiki> will read: [http://beyond-social.org/ Beyond Social]

==Audio-visual media upload==
You probably want not only to write, but also to use images, audio and video on the pages you'll be developing.

Wiki allows the following formats:
{| class="wikitable"
|-
! '''Medium''' !! '''Formats'''
|-
| image || png, gif, jpg, jpeg,  svg
|-
| audio || ogg, mp3
|-
| video || ogv, webm, mp4
|}

'''To upload''' you can use the picture icon on the menu. It asks you for the file name of the file you are going to upload (they must match) and a caption if you to say something about that image, video, or audio. 

When at this upload menu, <span style="background:yellow">instead of "caption" select "none" as the format of your upload</span>.

<nowiki>[[File:myimage.png]]</nowiki>


This action doesn't upload the file, it only inserts a bit syntax that allow you do the upload the file. In order to do so, you need to:
* Save the page you are working on
* Click on the red link of the file you want to upload
* Follow the instruction to upload your file

[[File:test.mp3]]


===image captions===
Captions can be added to images by using a vertical bar

<nowiki>[[File:myimage.jpg|Caption under the image]] </nowiki>

===Youtube videos===
You might also use Youtube videos.

To do so you have to write the '''video's id''' (the sequence of numbers and letters that follow '''?v=''' in the video url) in between these two tags: <nowiki><youtube>yourVideoID</youtube></nowiki>


As an example lets say you want to put the video https://www.youtube.com/watch?v=QH2-TGUlwu4 on a page.
# take the video's id: QH2-TGUlwu4
# write the youtube tags: <nowiki><youtube></youtube></nowiki>
# put the ID in between the tags <nowiki><youtube>QH2-TGUlwu4</youtube></nowiki>

And here it is, the Youtube video:
