+jtanimator v1.0, stage7
+
+A tool to convert PNG images into animations suitable for the JTPD-03-005 LED screen.
+
+The source image must be an RGB PNG (not indexed) using only the provided palette, stacking frames in vertical.
+The frames will be played in sequence, the first one being the topmost part. The image must be 32 pixels wide
+and 16 x n pixels high, n being the number of frames the final animation will have. The output should be exported
+to a file with .jt extension to be opened with the CoolLED1248 app.
+
+The palette is provided in GIMP format. Here it is for your reference in case you are unable to use this file:
+  0   0   0	Black
+255   0   0	Red
+  0 255   0	Green
+255 255   0	Yellow
+  0   0 255	Blue
+255   0 255	Magenta
+  0 255 255	Cyan
+255 255 255	White
+
+It has been tested with up to ~60 frames without issues. I have not done capacity tests so I do not know how many
+frames can the screen support. Bear in mind that 60 frames already take around 30 seconds to upload from the app.
+The speed of the animation can be edited in the app, but if you need something else by default you can change the
+"delays" attribute in the last line.
+
+I ignore if this script could work with models that have a different number of LEDs only changing a few numbers.
+Message me at @stage7@owo.cafe in the Fediverse if you try for yourself. I am also open to donations, just ask!
+
+This is free (libre) open-source software with no warranties. I will decide a license later, just please do not
+do anything nasty or take this script as your own. Thank you.
