 binfmt-dispatcher is a simple dispatcher for [binfmt_misc](https://www.kernel.org/doc/html/latest/admin-guide/binfmt-misc.html) that dynamically picks the best interpreter to use at runtime.
 
-## Usage
+## Installation
+binfmt-dispatcher is packaged in Fedora as of Fedora Linux 40. It can be installed with:
+
+```
+$ sudo dnf install binfmt-dispatcher
+```
+
+which will automatically register it as a binfmt_misc handler via systemd and installer a basic configuration.
+
+## Configuration
 binfmt-dispatcher should be registered as a binfmt_misc handler. If using systemd, this is accomplished via [binfmt.d](https://www.freedesktop.org/software/systemd/man/latest/binfmt.d.html) (sample configs are provided for [x86](data/binfmt-dispatcher-x86.conf) and [x86-64](data/binfmt-dispatcher-x86-64.conf)). It is recommended to prefix the config with `zz-` or something akin to ensure it's parsed last, as systemd processes these in lexicographic order. After installing the config, remember to restart [systemd-binfmt.service](https://www.freedesktop.org/software/systemd/man/latest/systemd-binfmt.service.html) for it to take effect.

 Configs are parsed in order and later settings win. A fully commented config is [provided](docs/binfmt-dispatcher.toml.example) and should be fairly self-explanatory.
 
+## Usage
 When run as an interpreter, binfmt-dispatcher will parse the configs, pick the best interpreter to use based on it and the binary being run, and then run it. If enabled (via the `use_muvm` config setting), binfmt-dispatcher will use [muvm](https://github.com/AsahiLinux/muvm) to execute the interpreter in a microVM if the system page-size is not 4k.
