Okay most of these didn't answer your question lol.
Here are some of the first steps you should take:
1. Get a good textbook. Most people like Genki 1 and Genki 2 you can download them for free online.
2. Learn Hiragana and Katakana first.
3. Use the textbook to get a basic understanding of grammar.
4. Get a native or near native speaker to correct your pronunciation and grammar.
5. The Genki books combined teach about 300 kanji out of like 2,110 plus kanji. When learning kanji stroke order is SUPER important, so make sure you're writing them correctly. I posted more info in a discussion I started. Check it out. If you have more questions don't be afraid to inbox me
