Okay, If your making a tellraw command, you should put an brackets " ".
Type on Command /tellraw
Then choose what kind of "@" do you want.
/tellraw @a
now put "{" for opening command.
/tellraw @a {
Then add brackets and put text inside the brackets.
/tellraw @a {"text"}
now follow me
/tellraw @a {"text":"}
/tellraw @a {"text":"Hello Guys!"}
Now you did it!
but theres more!!!
You can put a color on it !
/tellraw @a {"text":"Hello Guys!"} = /tellraw @a {"text":"Hello Guys!","}
add an "," for the color and put "color"
/tellraw @a {"text":"Hello Guys!","color"}
now add ":" again then pick color
/tellraw @a {"text":"Hello Guys!","color":"Color Name"}
