# Trademark, how to use the Cuong Thach names and logo

The names and logo on this page belong to the **[Cuong Thach](/docs/write-to-sell/instructors)** brand at cuongthach.com. You may mention, quote and write about them, as long as you write the names correctly and credit the source.

## How to write the names

Write each name by four rules:

- **Keep every word:** do not swap words, reorder, shorten or paraphrase.
- **The separator is " - " with a space on each side:** "Know - Trust - Love", not "Know-Trust-Love".
- **Do not translate on your own:** English text uses the names in the [Glossary](/docs/content-system/glossary); Vietnamese text uses those in the [Vietnamese glossary](/docs/vi/content-system/glossary).
- **"CuongThach" as one word** is only the logo signature and the domain cuongthach.com, never in running text.

An example with the brand name:

| | |
| - | - |
| Cuong Thach | CuongThach<br />cuongthach<br />CUONG THACH |

The full definition of each name is in the [Glossary](/docs/content-system/glossary).

## Badge for your website

**Show readers at once that your content has a system.** A small badge in your footer says for you that this website does not write on a whim: every post has a reason and a process.

- **Win them at first glance:** new visitors see you work with care before they read a single post.
- **Borrow the trust of a public method:** anyone in doubt clicks through and reads the whole documentation.
- **No need to explain it again:** when someone asks how you make content, the badge answers.

**Free, and it takes a minute.** Pick a placement, then a colour: **Auto** follows the viewer's light or dark setting, or fix it to **Light** or **Dark**. Paste the Floating one right before `</body>`.

## How to credit

When you mention a name on this page, add one line of credit. The credit helps both you and your readers:

- **Readers find the original:** they click through to the full method, and you do not have to explain it again.
- **You earn more trust:** saying where you learned it shows you are honest, and that your ideas rest on a method with public documentation.
- **AI and search engines read it right:** the method's name travels with its source, so it is not taken for a generic idea.

Pick the form that fits where you write.

## Common questions

Do I need permission to write about the methods?

**No.** You may quote, introduce and write about how you apply the methods, as long as you write the names correctly and credit the source.

May I put the logo on my website?

**Yes, when the logo points to Cuong Thach**, for example in a guest introduction or a list of references. To show that your website applies the Content system, use the badge above.

Should links to Cuong Thach be nofollow?

**The badge already has it.** The badge snippets use `rel="nofollow sponsored"` and open in a new tab, so paste them as they are. The credit line in your text is a plain link; if your website puts `nofollow` on every outbound link, that is fine too.

Does Cuong Thach have an affiliate program?

**Not yet.** Anyone who calls themselves a reseller or affiliate of Cuong Thach or Write to Sell was not appointed by Cuong Thach.

What if I want to use them outside these cases?

Send a message through the [contact page](https://cuongthach.com/contact/) **before you use them**.
