+# WebCodecs Test Files
+
+[TOC]
+
+## Instructions
+
+To add, update or remove a test file, please update the list below.
+
+Please provide full reference and steps to generate the test file so that
+any people can regenerate or update the file in the future.
+
+## Notes
+* When updating the sample offsets and descriptions for tests using mp4 files, it's easiest to use [mp4box.js](https://gpac.github.io/mp4box.js/test/filereader.html).
+  * Sample offsets can be copied from the "Sample View" tab after unchecking all but offset and size. Use a multi-line edit mode and clang-format to quickly format entries.
+  * Description entries can be found under moov.trak.mdia.minf.stbl.stsd in box view.
+    * avc1.avcC has an offset, size in the same view. Add 8 to offset and subtract 8 from the size to get the values the tests want.
+  * If you use ffprobe -show_packets to get sample offsets, you may need to add 4 to each `pos` value. You can tell if you need to by whether or not tests pass.
