+# NETfishing and Woofmeow branding
+
+The NETfishing and Woofmeow names, logos, icons, trade dress, and other source
+identifiers are reserved by Alexander Sellite and Rheannon Eisworth. Their
+presence in a GPL-licensed repository does not grant trademark rights or imply
+permission to represent another product as official.
+
+No trademark registration is asserted by this notice. Applicable rights may
+exist through use and other law.
+
+## Permitted references
+
+You may use the names NETfishing and Woofmeow truthfully to:
+
+- refer to the official game or development team;
+- state that software interoperates with or is a Mod for NETfishing;
+- link to an official repository or distribution page; and
+- discuss, review, criticize, or report on the Project.
+
+Use only the amount of branding reasonably necessary to identify the Project.
+Do not imply sponsorship, certification, endorsement, or official status.
+
+An unofficial Mod may use wording such as “Example Mod for NETfishing” if its
+name and presentation remain clearly distinct and it displays an unofficial
+notice.
+
+## Forks and redistributed code
+
+The GNU GPL permits forks and redistribution of covered code. A fork or
+modified distribution must:
+
+- use a distinct product name;
+- remove NETfishing and Woofmeow logos, icons, and official trade dress;
+- avoid confusingly similar names, domains, package identifiers, and account
+  names; and
+- clearly identify itself as independent and unofficial.
+
+These branding terms do not limit rights granted by the GPL to the software
+code or lawful nominative, descriptive, comparative, or fair use.
+
+Permission for broader branding use must be obtained in writing from both
+Alexander Sellite and Rheannon Eisworth.
