Firstly, enter your Minecraft username and current character
To add a character to your player card, click "Add Character"
When finished with the character, click "Finish", you'll notice the character count increase by one, that tells you it is saved
When you have added all the characters you want to, click "Generate Code", this creates code that is ready to be pasted into the wiki
Note: Cross-session saving has not been added, if you refresh or close the page all the data will be lost! Make sure you complete everything and copy the output before closing. (Saving and modification is a future hope)
