 ## 3_bananas.amf embedded texture
-3_bananas.amf embeds a strange-looking texture, but believe when applied to the model it ends up
-rendering correctly.
+3_bananas.amf embeds a strange-looking but valid texture, which when applied to the model renders correctly.
 
 (Note that this is a relatively rare example of a 3D model with an "uncompressed" embedded texture,
 may be useful for developers looking to test their assimp embedded texture implementations)
