Minor README Tweaks

[RichNSD]

Overview

The most significant change I made was to the > **Note** blocks so that they would display using their unique formatting (see Note & Warning Blocks).

I also added a Warning block that informs users they need to setup the AcodeX-Server in order to use AcodeX

The rest of the changes are just slight tweaks to wording and stuff to add clarity.

Note and Warning Blocks

Note and Warning blocks that include a colon :, like what you had originally, won't be formatted correctly.

❌ Incorrect Formatting

Raw Markdown Code:

> **Note:**
> Note block content.

> **Warning:**
> Warning block content.

Output (GitHub):

Note:
Note block content.

Warning:
Warning block content.

✅ Correct Formatting

Raw Markdown Code:

Actually I haven't used Note, Warning etc because that's not supported in acode

I know it's not currently supported in Acode's preview, but hopefully it will be eventually lol
