+ ============
+ === What ===
+ ============
+
+Gentoo patchsets for binutils are maintained as vendor branches of the upstream
+binutils-glb git repository. From there, we bundle all the commits into a tarball
+and distribute it via our public mirroring system.
+
+If you want specific info about a patch (like what it does or whose great idea 
+it was to change the code), read the patch!  We try to fill out the commit
+messages with useful info such as what it does, why it's needed, bug reports, 
+original creators, etc...  
+
+ =============
+ === Where ===
+ =============
+
+Currently, https://github.com/gentoo/binutils-gdb
+
+ ===========
+ === How ===
+ ===========
+ 
+The patch naming convention is precisely as generated by "git format-patch".
+
+All patches should apply with -p1 (so they can be used both with the legacy
+epatch function and the new, more strict eapply function).
+
+Commits where the commit message starts with "[no patch]" will not be included
+in the patch tarball. This is useful for changes to the tarball generation
+script, or for the addition of extra files that are not patches.
