+
+## Versions
+
+The `runsc` binaries and repositories are available in multiple versions and
+release channels. 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.
+
+### HEAD
+
+Binaries are available for every commit on the `master` branch, and are
+available at the following URL:
+
+`https://storage.googleapis.com/gvisor/releases/master/latest/runsc`
+
+Checksums for the release binary are at:
+
+`https://storage.googleapis.com/gvisor/releases/master/latest/runsc.sha512`
+
+For `apt` installation, use the `master` as the `${DIST}` below.
+
+### Nightly
+
+Nightly releases are built most nights from the master branch, and are available
+at the following URL:
+
+`https://storage.googleapis.com/gvisor/releases/nightly/latest/runsc`
+
+Checksums for the release binary are at:
+
+`https://storage.googleapis.com/gvisor/releases/nightly/latest/runsc.sha512`
+
+Specific nightly releases can be found at:
+
+`https://storage.googleapis.com/gvisor/releases/nightly/${yyyy-mm-dd}/runsc`
+
+Note that a release may not be available for every day.
+
+For `apt` installation, use the `nightly` as the `${DIST}` below.
+
+### Latest release
+
+The latest official release is available at the following URL:
+
+`https://storage.googleapis.com/gvisor/releases/release/latest`
+
+For `apt` installation, use the `release` as the `${DIST}` below.
+
+### Specific release
+
+A given release release is available at the following URL:
+
+`https://storage.googleapis.com/gvisor/releases/release/${yyyymmdd}`
+
+See the [releases][releases] page for information about specific releases.
+
+For `apt` installation of a specific release, which may include point updates,
+use the date of the release, e.g. `${yyyymmdd}`, as the `${DIST}` below.
+
+> Note: only newer releases may be available as `apt` repositories.
+
+### Point release
+
+A given point release is available at the following URL:
+
+`https://storage.googleapis.com/gvisor/releases/release/${yyyymmdd}.${rc}`
+
+Note that `apt` installation of a specific point release is not supported.
+
+## Install from an `apt` repository
+
+First, appropriate dependencies must be installed to allow `apt` to install
+packages via https:
+
+```bash
+sudo apt-get update && \
+sudo apt-get install -y \
+    apt-transport-https \
+    ca-certificates \
+    curl \
+    gnupg-agent \
+    software-properties-common
+```
+
+Next, the key used to sign archives should be added to your `apt` keychain:
+
+```bash
+curl -fsSL https://gvisor.dev/archive.key | sudo apt-key add -
+```
+
+Based on the release type, you will need to substitute `${DIST}` below, using
+one of:
+
+*   `master`: For HEAD.
+*   `nightly`: For nightly releases.
+*   `release`: For the latest release.
+*   `${yyyymmdd}`: For a specific releases (see above).
+
+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 release 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.
+
+## Install directly
+
+The binary URLs provided above can be used to install directly. For example, the
+latest nightly binary can be downloaded, validated, and placed in an appropriate
+location by running:
+
+```bash
+(
+  set -e
+  URL=https://storage.googleapis.com/gvisor/releases/nightly/latest
+  wget ${URL}/runsc
+  wget ${URL}/runsc.sha512
+  sha512sum -c runsc.sha512
+  rm -f 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
+```
