+# Steps for updating CEF
+
+- Go to http://opensource.spotify.com/cefbuilds/index.html
+- Download the latest standard distribution for Windows or Linux and extract
+- Delete `thirdparty/libcef/include` and `thirdparty/libcef/libcef_dll`
+- Copy `include` and `libcef_dll` from the CEF build to `thirdparty/libcef`
+- CD to `thirdparty/libcef`
+- Execute `python gen_libcef_paths.py libcef_dll > libcef.gypi`
+- Execute `python gen_libcef_stubs.py include > libcef.stubs`
+- Stderr will list unknown parameter or return types so edit `gen_libcef_stubs.py`
+to add them and run again
+- Copy binaries and resources from the CEF build to the prebuilt folders checking
+for any new file names to update in the gyp files and prebuilt builder. Note copy
+the binaries from the Release folder even to the debug prebuilt folders.
+- Reconfigure and build
+- Fix any API changes and make sure things work
+- Update `prebuilt/versions/cef` and `prebuilt/versions/cef_buildrevision`
+- Push up a patch to livecode and thirdparty
+- Kick off prebuilts
