I can't cover it much so here's you can do:
Use the provided tool that Creative Commons have given to you. Copy and paste the HTML text from the "Choose your License" page and better to choose "Yes, as long it is sharealike". This will give you the HTML text saying:
This work is licensed under [http://creativecommons.org/licenses/by-sa/3.0 Creative Commons Atrribution-ShareAlike 3.0 Unported License.
You can modify the HTML text whatever you want, but do so on your own risk.
My recommended solution is to modify it in the provided fashion. That is, attribution.
To do this, copy the code here:
<a rel="license" href="http://creativecommons.org/licenses/by-sa/3.0/"><img alt="Creative Commons License" style="border-width:0" src="https://i.creativecommons.org/l/by-sa/3.0/88x31.png" /></a><br />This work is licensed under a <a rel="license" href="http://creativecommons.org/licenses/by-sa/3.0/">Creative Commons Attribution-ShareAlike 3.0 Unported License</a>.
Then, you see the "This work is licensed under a" thing? Replace in the recommendation that we are going to do.
Name of the source, and the author of the source
For this, type in the phrase: "Arkheni is created by Airbus_Beluga."
The link origin of the source
Type the phrase: "Source: http://arstotzkanuniverse.wikidot.com/arkheni"
Copyright notice
This one is simple. Just type in the plain text:
"The content is licensed under <a href="https://creativecommons.org/licenses/by-sa/3.0">Creative Commons Atrribution-ShareAlike 3.0 License.</a>"
Disclaimer Notice:
Do this:
"Improper use of the content will be punishable by disciplinary action."
License Notice
Do this: "Creative Commons License is a material used by Creative Commons. Some Rights Reserved."
NOTE: "Some Rights Reserved" is used by Creative Commons in orderly fashion.
All Together
Now, copy this onto an HTML code block:
"Arkheni is created by Airbus_Beluga. The content is licensed under <a href="https://creativecommons.org/licenses/by-sa/3.0">Creative Commons Atrribution-ShareAlike 3.0 License.</a> Improper use of the content will be punishable by disciplinary action. Creative Commons License is a material used by Creative Commons. Some Rights Reserved."
Be sure to add this at the top of the formatting:
"<a rel="license" href="http://creativecommons.org/licenses/by-sa/3.0/"><img alt="Creative Commons License" style="border-width:0" src="https://i.creativecommons.org/l/by-sa/3.0/88x31.png" /></a><br />"
