+Just some notes
+---------------
+
+To build, one should use the following:
+
+$ time bash build.sh fetch prepare build package
+
+
+the final .zip is in:
+  C:\mozilla-source\firefox-85.0\obj-x86_64-pc-mingw32\dist
+
+
+* problem with old sed. does not recognize -z. using the one from Git might be a work around.
+
+
+BRANDING: resource files
+========================
+
+* build fail on missing stubinstaller (might be a FF bug as it should just take missing
+stuff from the nightly branding folder?)
+
+$ mkdir stubinstaller
+$ cp bgstub.jpg stubinstaller
+$ pwd
+/c/mozilla-source/firefox-85.0/browser/branding/librewolf
+$
+
+* checking all the different files in nightly and librewolf
+
+$ cd nightly
+$ find . | sort > /c/mozilla-source/branding-nightly.txt
+$ cd ../librewolf/
+$ find . | sort > /c/mozilla-source/branding-librewolf.txt
