+# Source tree layout
+
+Files are laid out so that a path names what a file is and the logical group it belongs to. Before adding, renaming or moving files, read the "Source tree layout" section of `doc/developer.texi`, also published at [https://ffmpeg.org/developer.html#Source-tree-layout](https://ffmpeg.org/developer.html#Source-tree-layout).
