@ -28,6 +28,7 @@ To build the daemon and `ctr` simple test client, the following build system dep
* Go 1.8.x or above (requires 1.8 due to use of golang plugin(s))
* Protoc 3.x compiler and headers (download at the [Google protobuf releases page](https://github.com/google/protobuf/releases))
* Btrfs headers and libraries for your distribution. Note that building the btrfs driver can be disabled via build tag removing this dependency.
For proper results, install the `protoc` release into `/usr/local` on your build system. For example, the following commands will download and install the 3.1.0 release for a 64-bit Linux host:

With the required dependencies installed, the `Makefile` target named **binaries** will compile the `ctr` and `containerd` binaries and place them in the `bin/` directory. Using `sudo make install` will place the binaries in `/usr/local/bin`. When making any changes to the gRPC API, `make generate` will use the installed `protoc` compiler to regenerate the API generated code packages.
> *Note*: A build tag is currently available to disable building the btrfs snapshot driver.
> Adding `BUILDTAGS=no_btrfs` to your environment before calling the **binaries**
> Makefile target will disable the btrfs driver within the containerd Go build.
Vendoring of external imports uses the [`vndr` tool](https://github.com/LK4D4/vndr) which uses a simple config file, `vendor.conf`, to provide the URL and version or hash details for each vendored import. After modifying `vendor.conf` run the `vndr` tool to update the `vendor/` directory contents. Combining the `vendor.conf` update with the changeset in `vendor/` after running `vndr` should become a single commit for a PR which relies on vendored updates.
Containerd will by default use `runc` found via the $PATH as the OCI-compliant runtime. You can specify the runtime directly with the `runtime` flag when starting containerd. However you specify the runtime, the expectation is that during the pre-release development cycle for containerd, the supported version of `runc` will track the current master branch of [`opencontainers/runc`](https://github.com/opencontainers/runc).
