The Thunderstore badges require a package's <code>namespace</code> and <code>name</code>.

Everything can be discerned from your package's URL. Thunderstore package URLs have a mostly consistent format:

<code>https://thunderstore.io/c/[community]/p/[namespace]/[packageName]</code>

For example: <code>https://thunderstore.io/c/lethal-company/p/notnotnotswipez/MoreCompany/</code>.
<ul>
  <li><code>namespace = "notnotnotswipez"</code></li>
  <li><code>packageName = "MoreCompany"</code></li>
</ul>

:::info[Risk Of Rain 2]
The 'default community', Risk of Rain 2, has an alternative URL:

<code>https://thunderstore.io/package/[namespace]/[packageName]</code>
:::

:::info[Subdomain Communities]
Some communities use a 'subdomain' alternative URL, for example, Valheim:

<code>https://valheim.thunderstore.io/package/[namespace]/[packageName]</code>
