+    /system/media/bootanimation.zip
+    /oem/media/bootanimation.zip
+
+## zipfile layout
+
+The `bootanimation.zip` archive file includes:

+    part0  \
+    part1   \  directories full of PNG frames
+    ...     /
+    partN  /
+
+## desc.txt format
+
+The first line defines the general parameters of the animation:
+
+    WIDTH HEIGHT FPS
+
+  * **WIDTH:** animation width (pixels)
+  * **HEIGHT:** animation height (pixels)
+  * **FPS:** frames per second, e.g. 60
+
+It is followed by a number of rows of the form:
+
+    TYPE COUNT PAUSE PATH [#RGBHEX CLOCK]
+
+  * **TYPE:** a single char indicating what type of animation segment this is:
+      + `p` -- this part will play unless interrupted by the end of the boot
+      + `c` -- this part will play to completion, no matter what
+  * **COUNT:** how many times to play the animation, or 0 to loop forever until boot is complete
+  * **PAUSE:** number of FRAMES to delay after this part ends
+  * **PATH:** directory in which to find the frames for this part (e.g. `part0`)
+  * **RGBHEX:** _(OPTIONAL)_ a background color, specified as `#RRGGBB`
+  * **CLOCK:** _(OPTIONAL)_ the y-coordinate at which to draw the current time (for watches)
+
+There is also a special TYPE, `$SYSTEM`, that loads `/system/media/bootanimation.zip`
+and plays that.
+
+## loading and playing frames
+
+Each part is scanned and loaded directly from the zip archive. Within a part directory, every file
+(except `trim.txt` and `audio.wav`; see next sections) is expected to be a PNG file that represents
+one frame in that part (at the specified resolution). For this reason it is important that frames be
+named sequentially (e.g. `part000.png`, `part001.png`, ...) and added to the zip archive in that
+order.
+
+## trim.txt
+
+To save on memory, textures may be trimmed by their background color.  trim.txt sequentially lists
+the trim output for each frame in its directory, so the frames may be properly positioned.
+Output should be of the form: `WxH+X+Y`. Example:
+
+    713x165+388+914
+    708x152+388+912
+    707x139+388+911
+    649x92+388+910
+
+If the file is not present, each frame is assumed to be the same size as the animation.
+
+## audio.wav
+
+Each part may optionally play a `wav` sample when it starts. To enable this, add a file
+with the name `audio.wav` in the part directory.
+
+## exiting
+
+The system will end the boot animation (first completing any incomplete or even entirely unplayed
+parts that are of type `c`) when the system is finished booting. (This is accomplished by setting
+the system property `service.bootanim.exit` to a nonzero string.)
+
+## protips
+
+### PNG compression
+
+Use `zopflipng` if you have it, otherwise `pngcrush` will do. e.g.:
+
+    for fn in *.png ; do
+        zopflipng -m ${fn}s ${fn}s.new && mv -f ${fn}s.new ${fn}
+        # or: pngcrush -q ....
+    done
+
+Some animations benefit from being reduced to 256 colors:
+
+    pngquant --force --ext .png *.png
+    # alternatively: mogrify -colors 256 anim-tmp/*/*.png
+
+### creating the ZIP archive
+
+    cd <path-to-pieces>
+    zip -0qry -i \*.txt \*.png \*.wav @ ../bootanimation.zip *.txt part*
+
+Note that the ZIP archive is not actually compressed! The PNG files are already as compressed
+as they can reasonably get, and there is unlikely to be any redundancy between files.
