+# CGround Platform Support
+
+This document details platforms that the CGround interpreter intends to support. 
+
+## Tier 1 - Actively tested
+
+These platforms are where CGround is actively tested and developed. These should have the best support and stability (as far as stability with CGround goes).
+
+* Linux x86_64, gcc, gnulibc
+* Linux x86_64, clang, gnulibc
+
+## Tier 2 - Sometimes tested
+
+These platforms are where CGround is sometimes tested. These should work most of the time, but some features may break.
+
+* Linux arm64, clang, gnulibc
+* MacOS x86_64, clang, included libc
+* MacOS arm64, clang, included libc
+* OpenBSD, built in cc, included libc
+* Haiku, gcc, included libc
+
+## Tier 3 - should work, untested
+
+These platforms, in theory, should be compatible with the CGround codebase. However, there has been zero testing, and there are no guarantees about whether stuff works.
+
+* Any modern UNIX-like OS/subsystem
+
+## Tier 4 - unlikely to work
+
+These platforms will not work with CGround unless modifications are made to either CGround or the platform it is running on.
+
+* Windows
