+## Supported platforms
+
+This list of supported platforms is current as of the branch / release to
+which it is attached.
+
+### Input
+
+Node.js relies on V8 and libuv. Therefore, we adopt a subset of their
+supported platforms.
+
+### Strategy
+
+Support is divided into three tiers:
+
+* **Tier 1**: Full test coverage and maintenance by the Node.js core team and
+  the broader community.
+* **Tier 2**: Full test coverage but more limited maintenance,
+  often provided by the vendor of the platform.
+* **Experimental**: Known to compile but not necessarily reliably or with
+  a full passing test suite. These are often working to be promoted to Tier
+  2 but are not quite ready. There is at least one individual actively
+  providing maintenance and the team is striving to broaden quality and
+  reliability of support.
+

+note1 - The gcc4.8-libs package needs to be installed, because node
+  binaries have been built with GCC 4.8, for which runtime libraries are not
+  installed by default. For these node versions, the recommended binaries
+  are the ones available in pkgsrc, not the one available from nodejs.org.
+  Note that the binaries downloaded from the pkgsrc repositories are not
+  officially supported by the Node.js project, and instead are supported
+  by Joyent. SmartOS images >= 16.4 are not supported because
+  GCC 4.8 runtime libraries are not available in their pkgsrc repository
