+# .deb Package Overview
+
+2020-01-20: Initial Commit
+
+## Important Information
+
+This section is a step-by-step tutorial.
+
+### Basic Installation
+
+Pick either debian (almost everything) or raspbian (special armv6 build for older models) and create the source file.
+```sh
+echo "deb https://ota.bike/raspbian/ buster main" > /etc/apt/sources.list.d/galmon.list
+echo "deb https://ota.bike/debian/ buster main" > /etc/apt/sources.list.d/galmon.list
+```
+
+Install the file used to ensure the software is verified.
+```sh
+apt-key adv --fetch-keys https://ota.bike/public-package-signing-keys/86E7F51C04FBAAB0.asc
+```
+
+Update your package list and install galmon. Then create a configuration file and start the daemon.
+```sh
+apt-get update && apt-get install -y galmon
+cp /etc/default/galmon /etc/default/ubxtool-ttyACM0
+systemctl enable --now ubxtool@ttyACM0
+```
+
+Alternate or multiple devices just repeats that:
+```sh
+cp /etc/default/galmon /etc/default/ubxtool-ttyACM3
+systemctl enable --now ubxtool@ttyACM3
+```
+
+### Automatic Updates
+
+Armbian and Raspbian have apt-daily timers enabled by default.
+
+Sources should update randomly twice daily but actual package updates
+will be applied randomly during a one-hour window depending on computer timezone.
+
+You can perform an immediate update by hand:
+```sh
+apt-get update && apt-get -y upgrade galmon && systemctl restart ubxtool@*
+```
+
+## Reference Information
+
+You can stop reading here if your insterest was limited to installing a compiled package.
+
+### One time steps for bootstrapping package build on a fresh git repo
+
+Run debmake in the source directory. It tries to autocreate 90% of everything you need in the debian folder.
+Key files: copyright, changelog, control, and anything else that looks interesting to cat. Once they exist, we're done.
+Refer to the manual's [tutorial](https://www.debian.org/doc/manuals/debmake-doc/ch04.en.html)
+
+### One time steps for creating package-specific files and scripts
+
+Inside the debian directory are files that begin with galmon, the name of the package as defined in the control file.
+- galmon.postinst: this script is run after installation to verify a system account exists.
+- galmon.default: this file is installed as /etc/default/galmon
+- galmon.ubxtool@.service: this unit file uses %i as a reference to the device for computers with multiple inputs.
+
+### How to build the package locally
+
+In short you need to set some variables, refer to profile-debuild.sh in the debian/ directory.
+After that, use debuild to install the package. Signing of the end result may fail and creating
+GPG key pairs is beyond the scope of this document but just make sure you match the email in the changelog.
+```sh
+apt-get install -y build-essential devscripts lintian diffutils patch patchutils
+git clone $flags galmon.git ; cd galmon
+./make-githash.h
+# create and source variables in /etc/profile.d/debuild.sh
+debuild
+dpkg -i ../*.deb
+```
+
+## Future maintenance considerations
+
+The githash.h files cannot change after the debuild process has started.
+For now, the Makefile used by debuild does not run that script and
+the files must be created before starting the debuild process.
+
+## Real World Build Results in January 2020
+
+Avoid arm6 computers. The arm6 used in cheap Raspberry Pi models is an expensive model to support 
+relative to the much faster arm7 and arm8 computers available. Compiling approaches 90 minutes at O3. 
+
+The arm7 and arm8 both compile in 20 to 30 minutes at -j1 -O3 but the 64 bit arm8 has approximately
+double the RAM requirements during compilation. To avoid swapping, increasing compile time 150%,
+use hardware with at least 1GB of RAM. The NanoPi Neo2 and NanoPi ZeroPi models with 512MB of RAM
+are perfect clients, but the OrangePi PCs with 1GB of RAM and the Allwinner H3 or H5 are
+better suited for smooth building.
+
+These are fast multi-core computers but we turn off parallel compiles because of limited RAM.
+
+## Why do this?
+
+Convenience, uniformity, and scalability:
+Hand-compiling software is fun, but vendor package management solutions
+exist to give us reliable unattended installations for free.
