 ## Installation
 
-### From Binaries (Recommended)
-Download the latest pre-compiled binaries from the [Releases](https://gitlab.speelman.ca/gamertan/sized/releases) page.
+### From source
+
+The following installs the current review branch, including scanner hardening
+not present in the published v1.0.0 release:
 
-### From Source
 ```bash
-git clone https://gitlab.speelman.ca/gamertan/sized.git
+git clone --branch sizequeen-scan-hardening https://gitea.speelman.ca/gamertan/sized.git
 cd sized
-make install # Installs binary and man page
+cargo install --locked --path .
 ```
 
+Cargo installs to `~/.cargo/bin`. For the published source instead, check out
+`v1.0.0` before installing. `make install PREFIX="$HOME/.local"` additionally
+installs the man page without requiring administrator privileges.
+
+### Existing release files
+
+The [v1.0.0 release](https://gitea.speelman.ca/gamertan/sized/releases/tag/v1.0.0)
+has source archives, a macOS arm64 executable, a man page and completions.
+It has no Linux binary, architecture-labelled binary archive or `.deb` attachment.
+See the [README](README.md#installation) for current installation guidance.

 ## Basic Usage
 
 By default, `sized` analyzes the current directory recursively and displays a table of the immediate children.
