 Compiling systems on linux or via `mix nerves.system.shell`? Don't forgot about
 `make help` and other tips from the Buildroot manual (thanks @ericr3r)

 Configuring the Elixir Logger to show SASL reports can help debug unexpected
 GenServer restarts.

 Erlinit is a small program that starts the Erlang VM on boot. It has many
 options - especially for debugging startup issues.

 Get all of the default packages for starting a new Nerves project by depending
 on `:nerves_pack` https://github.com/nerves-project/nerves_pack

 Get some insights to Nerves internals with this high level overview of the
 Nerves architecture and choice to use the BEAM VM https://youtu.be/VzOaSvTcvU4

+%
 Identify your Nerves devices using a unique ID that's already programmed into
 the hardware using the boardid command. Details at
 https://github.com/nerves-project/boardid/ and the boardid.config file.
-
+%
 Make small code changes to your running application by copy/pasting Elixir
 source files at the IEx prompt.
-
+%
 Need more than Elixir logs? Run `dmesg` to see log messages from device drivers
 and the Linux kernel. Nerves also routes kernel log messages to the Elixir
 logger.
-
+%
 Nerves automatically reboots devices when the Erlang VM exits. This can make
 some debugging harder, but you can easily disable it to let those sessions hang
 for debugging
-
+%
 Nerves enables hardware watchdogs and connects them to Erlang's heart feature
 to detect and recover from the Erlang VM hanging. See
 https://embedded-elixir.com/post/2018-12-10-heart/ to learn more about this.

 Nerves maintains a set of examples for common use-cases with devices. Things
 like running a phoenix app, using SQLite, controlling GPIO, using Zig lang, and
 more! https://github.com/nerves-project/nerves_examples

 Nerves stores all BEAM files, the Erlang runtime and various support libraries
 and apps in a compressed and read-only SquashFS filesystem. The writable
 application partition is mounted at `/data`

 Nerves stores all BEAM files, the Erlang runtime and various support
 libraries/apps in a compressed and read-only SquashFS filesystem. Need to write
 to disk? Use the application partition mounted R/W at `/data`

 Run `Nerves.Runtime.revert` to go back to the previously loaded firmware.

 See if someone has already implemented support for a sensor or other hardware
 device that you have by checking https://elixir-circuits.github.io/.

 Sometimes when compiling Nerves systems, order matters! Use `make
 show-build-order` while in `mix nerves.system.shell` to see the compilation
 order and make sure all your 🦆🦆 are in a row (thanks @ericr3r!)
-
+%
 Sometimes, you just need to see whats on your Nerves device's disk. Luckily,
 there are a few ways to do that. You can even use VSCode!

+%
 Use `RingLogger.next` to dump the current log buffer to screen. Use
 `log_attach` from `Toolshed` to attach the current session to the Elixir logger
 for live logs. https://hexdocs.pm/toolshed/Toolshed.Log.html#log_attach/1
-
+%
 Use `mix firmware.unpack` to decompress a local copy of your firmware on host
 and inspect the files within before installing on device
-
+%
 Use the `RamoopsLogger` backend to store log messages in DRAM that can survive
 unexpected reboots. https://github.com/smartrent/ramoops_logger

 Want more traditional shell tools in your Nerves IEx? Use Toolshed! Its
 included by default and has may familiar functions, such as `cat`, `ls`, or
 even `weather` 🌤️ https://hexdocs.pm/toolshed
