+Platform support
+----------------------------------------
+
+SIL Kit provides two tiers of platform support
+
+.. list-table:: Support Tiers
+
+   * - Tier 1
+     - Officially build, continuously tested targets for which we provide binary
+       packages
+   * - Tier 2
+     - | Targets for which we have (limited) build support but which
+       | are not continuously tested and no packages are provided from us
+
+A platform
+hereby is defined by a combination of the used operating system (OS), the CPU
+Architecture (eg. x86 or ARM64) and the compiler/toolchain used. An example
+would be `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
+please report via the 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.
+
+
