## :memo: Where do I start?

### Step 1: Change the title and add a tag

- [x] Create my first HackMD note (this one!)
- [X] Change its title
- [X] Add a tag

:rocket:

### Step 2: Write something in Markdown

Let's try it out!
Apply different styling to this paragraph:
**HackMD gets everyone on the same page with Markdown.** ==Real-time collaborate on any documentation in markdown.== Capture fleeting ideas and formalize tribal knowledge.

- [x] **Bold**
- [x] *Italic*
- [ ] Super^script^
- [ ] Sub~script~
- [X] ~~Crossed~~
- [x] ==Highlight==

This is really fun to create a note. Should be a good way to go.

:bulb: **Hint:** You can also apply styling from the toolbar at the top :arrow_upper_left: of the editing area.

- LaTeX for formulas

$$
x = {-b \pm \sqrt{b^2-4ac} \over 2a}
$$

$$
\sqrt{b^2-4ac} \over 2a
$$

def first_function(x):
    for x in range(5):
        print(x)

This function will loop from 0 to 4 and print them accordingly.
