   9 Support for different platforms ("targets") are organized into three tiers,
  10 each with a different set of guarantees. For more information on the policies
  11 for targets at each tier, see the [Target Tier Policy](target-tier-policy.md).
  12
  13 Targets are identified by their "target triple" which is the string to inform
  14 the compiler what kind of output should be produced.
  15
  16 ## Tier 1 with Host Tools
  17
  18 Tier 1 targets can be thought of as "guaranteed to work". The Rust project
  19 builds official binary releases for each tier 1 target, and automated testing
  20 ensures that each tier 1 target builds and passes tests after each change.
  21
  22 Tier 1 targets with host tools additionally support running tools like `rustc`
  23 and `cargo` natively on the target, and automated testing ensures that tests
  24 pass for the host tools as well. This allows the target to be used as a
  25 development platform, not just a compilation target. For the full requirements,
  26 see [Tier 1 with Host Tools](target-tier-policy.md#tier-1-with-host-tools) in
  27 the Target Tier Policy.
  28
  29 All tier 1 targets with host tools support the full standard library.

  50 ## Tier 1
  51
  52 Tier 1 targets can be thought of as "guaranteed to work". The Rust project
  53 builds official binary releases for each tier 1 target, and automated testing

  55 the full requirements, see [Tier 1 target
  56 policy](target-tier-policy.md#tier-1-target-policy) in the Target Tier Policy.
  57
  58 At this time, all Tier 1 targets are [Tier 1 with Host
  59 Tools](#tier-1-with-host-tools).
  60
  61 ## Tier 2 with Host Tools
  62
  63 Tier 2 targets can be thought of as "guaranteed to build". The Rust project
  64 builds official binary releases for each tier 2 target, and automated builds
  65 ensure that each tier 2 target builds after each change. Automated tests are
  66 not always run so it's not guaranteed to produce a working build, but tier 2
  67 targets often work to quite a good degree and patches are always welcome!
  68
  69 Tier 2 targets with host tools additionally support running tools like `rustc`
  70 and `cargo` natively on the target, and automated builds ensure that the host
  71 tools build as well. This allows the target to be used as a development
  72 platform, not just a compilation target. For the full requirements, see [Tier 2
  73 with Host Tools](target-tier-policy.md#tier-2-with-host-tools) in the Target
  74 Tier Policy.
  75
  76 All tier 2 targets with host tools support the full standard library.
  77
  78 **NOTE:** The `rust-docs` component is not usually built for tier 2 targets,
  79 so Rustup may install the documentation for a similar tier 1 target instead.

 196 Official builds are not available. For the full requirements, see [Tier 3

 206 [`no_std`]: https://rust-embedded.github.io/book/intro/no-std.html
 207
 208 The `host` column indicates whether the codebase includes support for building
