Here are some basic HTML commands:

```html
<b>Bold</b> text
```

This `<b>` tag will make your text bold,

```html
<i>Italic</i> text
```

and this `<i>` tag will make your text italic.

Headers can be created with these tags: `<h1>`, `<h2>` all the way to `<h6>`.

If you want a picture on your web page, you can use the `<img>` tag.
