+
+## Versions
+
+The `runsc` binaries and repositories are available in multiple versions and
+release channels. First, you should pick the version you'd like to install. For
+experimentation, the nightly release is recommended. For production use, the
+latest release is recommended.
+
+After selecting an appropriate release channel from the options below, proceed
+to the preferred installation mechanism: manual or from an `apt` repository.
+
+### Nightly
+
+Nightly releases are built most nights from the master branch, and are available
+at the following URL:
+
+   `https://storage.googleapis.com/gvisor/releases/nightly/latest`
+
+Specific nightly releases can be found at:
+
+   `https://storage.googleapis.com/gvisor/releases/nightly/${yyyy-mm-dd}`
+
+Note that a release may not be available for every day.
+
+To use a nightly release, use one of the above URLs for `URL` in the manual
+instructions below. For `apt`, use `nightly` for `DIST` below.
+
+### Latest release
+
+The latest official release is available at the following URL:
+
+   `https://storage.googleapis.com/gvisor/releases/release/latest`
+
+To use the latest release, use the above URL for `URL` in the manual
+instructions below. For `apt`, use `latest` for `DIST` below.
+
+### Specific release
+
+A given release release is available at the following URL:
+
+  `https://storage.googleapis.com/gvisor/releases/release/${yyyymmdd}`
+
+See the [releases][releases] page for information about specific releases.
+
+This will include point updates for the release, if required. To use a specific
+release, use the above URL for `URL` in the manual instructions below. For
+`apt`, use `${yyyymmdd}` for `DIST` below.
+
+### Point release
+
+A given point release is available at the following URL:
+
+  `https://storage.googleapis.com/gvisor/releases/release/${yyyymmdd}.${rc}`
+
+Unlike the specific release above, which may include updates, this release will
+not change. To use a specific point release, use the above URL for `URL` in the
+manual instructions below. For apt, use `${yyyymmdd}.${rc}` for `DIST` below.
+
+## From an `apt` repository
+
+First, appropriate dependencies must be installed to allow `apt` to install
+packages via https:
+
+```bash
+sudo apt-get update && \
+sudo apt-get install -y \
+    apt-transport-https \
+    ca-certificates \
+    curl \
+    gnupg-agent \
+    software-properties-common
+```
+
+Next, the key used to sign archives should be added to your `apt` keychain:
+
+```bash
+curl -fsSL https://gvisor.dev/archive.key | sudo apt-key add -
+```
+
+Based on the release type, you will need to substitute `${DIST}` below, using
+one of:
+
+ * `nightly`: For all nightly releases.
+ * `latest`: For the latest release.
+ * `${yyyymmdd}`: For specific releases.
+ * `${yyyymmdd}.${rc}`: For a specific point release.
+
+The repository for the release you wish to install should be added:
+
+```bash
+sudo add-apt-repository \
+   "deb https://storage.googleapis.com/gvisor/releases" \
+   "${DIST}" \
+   main
+```
+
+For example, to install the latest official release, you can use:
+
+```bash
+sudo add-apt-repository \
+   "deb https://storage.googleapis.com/gvisor/releases" \
+   latest \
+   main
+```
+
+Now the runsc package can be installed:
+
+```bash
+sudo apt-get update && sudo apt-get install -y runsc
+```
+
+If you have Docker installed, it will be automatically configured.
+
+## Manually
+
+After selecting an appropriate `URL` above, you can download `runsc` directly
+from `${URL}/runsc` ([latest][latest-nightly]) and a checksum hash from
+`${URL}/runsc.sha512` ([latest][latest-hash]).
+
+For example, this binary can be downloaded, validated, and placed in an
+appropriate location by running:
+
+```bash
+(
+  set -e
+  wget ${URL}/runsc
+  wget ${URL/runsc.sha512
+  sha512sum -c runsc.sha512
+  sudo mv runsc /usr/local/bin
+  sudo chown root:root /usr/local/bin/runsc
+  sudo chmod 0755 /usr/local/bin/runsc
+)
+```
+
+**It is important to copy this binary to a location that is accessible to all
+users, and ensure it is executable by all users**, since `runsc` executes itself
+as user `nobody` to avoid unnecessary privileges. The `/usr/local/bin` directory
+is a good place to put the `runsc` binary.
+
+After installation, the`runsc` binary comes with an `install` command that can
+optionally automatically configure Docker:
+
+```bash
+runsc install
+```
