+steam-runtime-tools — Steam Runtime integration for the Steam client
+====================================================================
+
+The steam-runtime-tools library provides low-level Unix-specific tools
+and functionality for the Steam client.
+
+To support multiple architectures (currently only `i386` and `x86_64`
+are supported), you will need to build it once for each architecture and
+install at least the helper tools in `/usr/libexec/steam-runtime-tools-0`
+(the `libsteam-runtime-tools-0-helpers` package) for every architecture
+in parallel.
+
+The helper tools are located relative to the shared library, so it's OK
+to bundle steam-runtime-tools alongside some other stack in this layout:
+
+    anything/
+        lib/
+            x86_64-linux-gnu/
+                libsteam-runtime-tools-0.so.0
+        libexec/
+            steam-runtime-tools-0/
+                i386-linux-gnu-*
+                x86_64-linux-gnu-*
+
+as long as the program that is linked to `libsteam-runtime-tools-0.so.0`
+can find it (via a `RPATH` or `RUNPATH` or by setting the `LD_LIBRARY_PATH`
+environment variable).
