+# Credits and bundled assets
+
+Flipnote Editor was developed for RexiMemo by Rekushi. This standalone edition
+retains its interface, drawing tools and artwork. Original editor code is
+covered by the accompanying GNU AGPL version 3 licence.
+
+Thanks to **bizkit** and **CommandCreep** for creating sprites for the editor.
+
+## Dependencies
+
+- **flipnote.js**, James Daniel. MIT licence. The unminified browser build is
+  bundled in `assets/vendor/flipnote.js`; its licence is beside it. Used here
+  to read PPM files, not to write them.
+  Source: https://github.com/jaames/flipnote.js
+- **bidi-js**. MIT licence, retained at
+  `assets/flipnote-editor/bidi-LICENSE.txt`.
+- The Arabic joining algorithm follows **arabic-reshaper**. Its MIT licence is
+  retained at `assets/flipnote-editor/arabic-reshaper-LICENSE.txt`.
+
+## Artwork
+
+The original interface assets are included so this copy looks like the editor.
+
+Nintendo's names and Flipnote Studio are used to describe compatibility. This
+project is independent of Nintendo.
