+### Supported Targets
-Freestanding means that you do not directly interact with the OS
-or you are writing your own OS.
+#### Tier 1 Support
-Note that if you use libc or other libraries to interact with the OS,
-that counts as "freestanding" for the purposes of this table.
+ * Not only can Zig generate machine code for these targets, but the standard
+ library cross-platform abstractions have implementations for these targets.
+ Thus it is practical to write a pure Zig application with no dependency on
+ libc.
+ * The CI server automatically tests these targets on every commit to master
+ branch, and updates ziglang.org/download with links to pre-built binaries.
+ * These targets have debug info capabilities and therefore produce stack
+ traces on failed assertions.

+#### Tier 2 Support
+
+ * There may be some standard library implementations, but many abstractions
+ will give an "Unsupported OS" compile error. One can link with libc or other
+ libraries to fill in the gaps in the standard library.
+ * These targets are known to work, but are not automatically tested, so there
+ are occasional regressions.
+ * Some tests may be disabled for these targets as we work toward Tier 1
+ support.
+
+#### Tier 3 Support
+
+ * The standard library has little to no knowledge of the existence of this
+ target.
+ * Because Zig is based on LLVM, it has the capability to build for these
+ targets, and LLVM has the target enabled by default.
+ * These targets are not frequently tested; one will likely need to contribute
+ to Zig in order to build for these targets.
+ * The Zig compiler might need to be updated with a few things such as
+ - what sizes are the C integer types
+ - C ABI calling convention for this target
+ - bootstrap code and default panic handler
+
+#### Tier 4 Support
+
+ * Support for these targets is entirely experimental.
+ * LLVM may have the target as an experimental target, which means that you
+ need to use Zig-provided binaries for the target to be available, or
+ build LLVM from source with special configure flags.
