"Here is my plan."
Translation:Вот мой план.
Quoting my explanation from this thread https://www.duolingo.com/comment/11563437$from_email=comment&comment_id=11564028:
Both can be translations of "here", but in practice they have slightly different meanings. "Вот" is used to demonstrate that something is here. "Здесь" is used to demonstrate that something is here.
You are asked about a location of something (e.g. a book). You point at it and say "Здесь". (You can also use "тут" - the two are interchangeable.)
The difference with "вот" is subtle, but in the same example you would use "вот" if you were at first uncertain whether you actually have that book. You look for it, and upon seeing it you exclaim "вот!". The emphasis is on its existence rather then location.
P.S. In the above example both "здесь" and "вот" can be used, they simply emphasise different aspects. On the other hand, there are circumstances where only one of them can be meaningfully used:
Здесь холодно - It's cold here. Здесь нельзя курить - No smoking is allowed here.
"Вот" cannot be used in these examples at all.
