+#### Bare Metal
+There are a few options for acquiring pict-rs to run outside of docker.
+1. Packaged via your distro of choice
+2. Binary download from [the releases page](https://git.asonix.dog/asonix/pict-rs/tags)
+3. Compiled from source
+
+##### Distro Package
+If getting pict-rs from your distro, please make sure it's a recent version (meaning 0.3.x stable,
+or 0.4.0-rc.x). If it is older, consider using an alternative option for installing pict-rs. I am
+currently aware of pict-rs packaged in [the AUR](https://aur.archlinux.org/packages/pict-rs) and
+[nixpkgs](https://search.nixos.org/packages?channel=23.05&from=0&size=50&sort=relevance&type=packages&query=pict-rs),
+but there may be other distros that package it as well.
+
+##### Binary Download
+pict-rs provides precompiled binaries that should work on any linux system for x86_64, aarch64, and
+armv7h on [the releases page](https://git.asonix.dog/asonix/pict-rs/tags). If downloading a binary,
+make sure that you have the following dependencies installed:
+- `imagemagick` 7
+- `ffmpeg` 5 or 6
+- `exiftool` 12 (sometimes called `perl-image-exiftool`)
+
+These binaries are called by pict-rs to process uploaded media, so they must be in the `$PATH`
+available to pict-rs.
+
+##### Compile from Source
+pict-rs can be compiled from source using a recent version of the rust compiler. I do development on
+1.69 and produce releases on 1.70. pict-rs also requires the `protoc` protobuf compiler to be
+present at build-time in order to enable use of
+[`tokio-console`](https://github.com/tokio-rs/console).
+
+Like the Binary Download option, `imagemagick`, `ffmpeg`, and `exiftool` must be installed for
+pict-rs to run properly.
