 ## gandi-live-dns-rust
 
-A program that can set the IP addresses for configured DNS entries in [Gandi](https://gandi.net)'s domain configuration.

+A program that can set the IP addresses for configured DNS entries in
+[Gandi](https://gandi.net)'s domain configuration. Thanks to Gandi's
+[LiveDNS API](https://api.gandi.net/docs/livedns/),
+this creates a dynamic DNS system.
+
+If you want to host web services but you don't have a static IP address, this
+tool will allow you to keep your domains pointed at the right IP address. This
+program can update both IPv4 and IPv6 addresses for one or more domains and
+subdomains. It's a one-shot tool that's meant to be managed with a systemd timer
+or cron.
 
 Inspired by [cavebeat's similar tool](https://github.com/cavebeat/gandi-live-dns),

 ## Usage
 
+> Warning!
+> 
+> This tool does not rate limit itself, or otherwise do anything that limits how
+> often it sends changes to Gandi's servers. It's up to you to use the tool
+> properly and avoid abusing Gandi's servers. The tool is one-shot, so all you
+> have to do is to avoid running it too often.
+
+### Prebuilt binaries
+
+`gandi-live-dns-rust` provides pre-built binaries with the releases. See the
+[releases page](https://github.com/SeriousBug/gandi-live-dns-rust/releases) to
+get the latest version. These binaries are statically linked, and provided for
+both Linux and Windows, including ARM architectures for the Linux version.
+
+Download the latest version from the releases page, extract it from the archive, and place it somewhere in your `$PATH` to use it.
+
 - Create a file `gandi.toml`, then copy and paste the contents of [`example.toml`](https://raw.githubusercontent.com/SeriousBug/gandi-live-dns-rust/master/example.toml)
 - Follow the instructions in the example config to get your API key and put it in the config
 - Follow the examples in the config to set up the entries you want to update
-- Download and extract the correct binary from the [releases page](https://github.com/SeriousBug/gandi-live-dns-rust/releases) and place it in your `PATH`, or just the current directory
-- Run `gandi-rust-dns-updater` to update your DNS entries
+- Run `gandi-live-dns` inside the directory with the configration to update your DNS entries
 
-> Warning!
-> 
-> This tool does not rate limit itself, or otherwise do anything that limits how often it sends changes to Gandi's servers.
-> It's up to you to use the tool properly and avoid abusing Gandi's servers. The tool is one-shot, so all you have to do is
-> to avoid running it too often.
+### With docker
+
+`gandi-live-dns-rust` has Docker images available for x86_64, arm64, armv6, and armv7 platforms.
+Follow the steps below to use these images.
+
+- Create a file `gandi.toml`, then copy and paste the contents of [`example.toml`](https://raw.githubusercontent.com/SeriousBug/gandi-live-dns-rust/master/example.toml)
+- Follow the instructions in the example config to get your API key and put it in the config
+- Follow the examples in the config to set up the entries you want to update
+- Run `docker run --rm -it -v $(pwd)/gandi.toml:/gandi.toml:ro seriousbug/gandi-live-dns-rust:latest`
+
+> Docker doesn't [support IPv6](https://docs.docker.com/config/daemon/ipv6/) out
+> of the box. Check the linked page to enable it, or use the native option.
+
+> If you get [errors](https://stackoverflow.com/questions/42248198/how-to-mount-a-single-file-in-a-volume) about not finding the config file, make sure your command
+> has a full path to the config file (`$(pwd)/gandi.toml` part). Otherwise
+> Docker will create a directory.
+
+## Development
+
+### Local builds
+
+`cargo build` and `cargo build --release` are sufficient for development and release builds.
+No special instructions are needed.
+
+### Making a release
+
+To make a release, first set up `cross` and `docker`. Make sure you log into
+Docker with `docker login`. Then follow these steps:
+
+- bump up the version in `Cargo.toml` according to [semver](https://semver.org/)
+- run `./make-release.sh`
+    > This will build binaries, then package them into archives, as well as
+    > build and upload docker images.
+- Create a release on Github
+    - Make sure to create a tag for the release version on `master`
+    - Upload the binary archives to the Github release
