+# 1password-cli
+
+Install the [1Password CLI](https://developer.1password.com/docs/cli/) (`op`) from 1Password's signed apt repository.
+
+## Usage
+
+```json
+"features": {
+  "ghcr.io/CargoSense/devcontainer-features/1password-cli:1": {}
+}
+```
+
+## Options
+
+This Feature has no options. It installs the latest `1password-cli` package.
+
+## Signing in
+
+The 1Password desktop app's CLI integration does not reach into a container, so `op` signs in with your account details instead:
+
+```sh
+op account add --address <your-team>.1password.com --email <you@example.com>   # once; asks for your Secret Key and password
+eval "$(op signin)"                                                            # in each terminal that needs it
+```
+
+`op account add` stores the account in `~/.config/op`. Mount a named volume there (for example `type=volume,source=op-config,target=/home/vscode/.config/op`, owned by the remote user) to keep it across rebuilds.
+
+## OS Support
+
+This Feature should work on recent versions of Debian/Ubuntu and Linux distributions using the [apt](https://wiki.debian.org/AptCLI) management tool, on `amd64` and `arm64`.
