+### installation
+
+Prebuilt static (musl) and glibc binaries for `x86_64` and `aarch64` are attached to every [release](https://github.com/DeityLamb/dfetch/releases).
+
+```sh
+cargo install --git https://github.com/DeityLamb/dfetch
+```
+
+### releasing
+
+Bump `version` in `Cargo.toml`, commit, then push a matching tag:
+
+```sh
+git tag v0.1.2 && git push origin v0.1.2
+```
+
+The `Release` workflow builds all targets and publishes a GitHub release with generated notes.
