 # SIG/AltArch Wiki
 
-@TODO - fill in :)
+This is a Wiki for the Rocky Linux Alternative Architectures SIG.  It's an information repository that records the group efforts and findings.
+
+The AltArch special interest group looks at porting Rocky Linux to diverse or non-traditional platforms.  Think small boards (Raspberry Pi and relatives), or other processor architectures like RISC-V and armhfp (32-bit ARM).
+
+
+This Wiki is browseable at **https://sig-altarch.rocky.page** .
