How to use /tellraw in minecraft

Today I will be showing you how to make custom text in chat!
Tip: If you use hex codes, put #F before your hex! Example "color":"#F88edff" for very light blue text.
Command :
/tellraw @a {"text":"Text Here","color":"white"}
advanced command :
/tellraw @a {"text":"Subscribe","color":"#F88edff","bold":"true","underlined":"true","italic":"true"}

Enjoy!
