As with any other (European) language, you usually start with words and then you'll have to learn some grammar - at least if you'd like to eventually be able to form correct sentences ;) This is quite important, as for some reason lots of Germans tend to think that people who try to speak German without knowing the grammar (endings/cases, vowel changes in verbs, etc.) are not too bright and will treat them accordingly. One thing I can tell you: it's a really good idea to try to learn the gender of the nouns from the start, for example that it's "der Name" (masculine), even if you don't exactly need to know that in order to say "Mein Name ist..." (My name is...). However, it will help you a lot later on. Good luck!
