What does "aquella necesaria" mean?
Basically, I don't understand the use of the phrase in this link. If the pdf doesn't work for you, here's the sentence:
En este curso le ofrecemos explicaciones sencillas, en español, sobre la gramática básica italiana, aquella necesaria para entablar una conversación no especializada, informal.
The literal meaning is not really helpful (that one necessary? should there be a "que es" between the words?) so I don't know what the abstract meaning could be. Also, what does the phrase refer to (since it is feminine)? Does it refer to "gramática"?

I believe aquella is missing an accent which would make it a demonstrative pronoun... aquélla representing gramática.
...aquélla (gramática básica) necesaria para entablar una conversación no especializada, informal.
This part doesn't translate very well literally. I would restructure it like this in English:
In this course we offer simple explanations in Spanish; covering the basic grammar necessary to strike up a simple conversation.

In this course we offer simple explanations, in Spanish, covering basic Italian grammar; everything you'll need to strike up a simple conversation.

I would read it as:
In this course we offer you simple explanations, in Spanish, about basic Italian grammar, that necessary in order to start a unspecialized, informal conversation.
You could look at that necessary as short for that which is necessary and I believe in Spanish the que es can be dropped just as I dropped which is in English.
And yes, I think it refers to gramática.
I am an intermediate level learner, so await other opinions as well.
It could be: "la necesaria...", without "aquella".
