 SRB2 Debian package!
 Hi there, to rebuild this package just use the SRB2 Makefile system, or, optionally, run
-dpkg-buildpackage in the in /bin/Resources directory. You can build these with or without a key
+dpkg-buildpackage in the in /assets directory. You can build these with or without a key
 if you want, but if you want to put these on a repo, generate your own GnuPG key as per the
 https://help.ubuntu.com/community/GnuPrivacyGuardHowto instructions and pass the -k<keyid>
 command to debuild. Make sure you export the key footprint and give them to your users to install
 with apt-key add. Thanks!

+Signing for Launchpad PPA
+
+First, follow the above instructions to generate a GnuPG key with your identity. You will need
+to publish the fingerprint of that key to Ubuntu's key server.
+
+    https://help.ubuntu.com/community/GnuPrivacyGuardHowto#Uploading_the_key_to_Ubuntu_keyserver
+
+Next, you will have to add that key fingerprint to your Launchpad account. Go to your Launchpad
+profile and click the yellow Edit button next to "OpenPGP keys". Once you add the key, you can
+upload signed source packages and publish them onto your PPA.
+
+IF YOU UPLOAD A PACKAGE and Launchpad does NOT send you a confirmation or rejection email, that
+means your key is not set up correctly with your Launchpad account.
+
+
+Building for Launchpad PPA
+
+Use these steps to prepare building a source package for Launchpad:
+
+    1. Highly recommend copying the assets/ folder to outside your repo folder, or else the asset
+       files may be included in the main source package, when you build that.
+    2. cd [wherever-your-assets-folder-is]/assets/
+    3. debuild -T clean (optional, if you already have asset files)
+
+Building the source package is a two-step process:
+
+    1. debuild -T build (this downloads the asset files from srb2.org if necessary)
+    2. debuild -S (builds the source package for Launchpad, including the asset files)
+
+Then follow the instructions at <https://help.launchpad.net/Packaging/PPA/Uploading> to upload
+to your PPA and have Launchpad build your binary deb packages.
