+Platform support
+-----------------------
+
+SIL Kit provides three tiers of platform support
+
+.. list-table:: Support Tiers
+   :widths: 15 85
+
+   * - Tier 1
+     - Essential targets. Continuously tested and
+       official binary packages are provided.
+   * - Tier 2
+     - Officially supported targets. Continuously tested
+       but NO binary packages are provided
+   * - Tier 3
+     - | Targets for which we have (limited) build support but which
+       | are not continuously tested and no packages are provided
+
+A platform is hereby defined by the combination of the used operating system (OS), the CPU architecture (eg. x86 or ARM64) and the compiler/toolchain used.
+For example,  `Ubuntu 20.04 x86_64 Clang 10`.
+
+SIL Kit should compile and run on
+any POSIX platform. If you have feedback for different targets or platforms not listed here,
+please report them using GitHub Issues. Thanks!
+
+A target may be upgraded to
+`Tier 1` once we have continuous testing for it in place and we have binary
+packages available for it.
