+## Software
+
+oasis uses smaller and simpler implementations of libraries and
+tools whenever possible:
+
+- musl instead of glibc
+- sbase instead of coreutils
+- ubase instead of util-linux
+- pigz instead of gzip
+- mandoc instead of man-db
+- bearssl instead of openssl
+- oksh instead of bash
+- sdhcp instead of dhclient or dhcpcd
+- vis instead of vim or emacs
+- bc-gh instead of GNU bc
+- byacc instead of bison
+- perp and sinit instead of sysvinit or systemd
+- netsurf instead of chromium or firefox
+
+These packages are grouped into logical [sets], and the full list
+is available in the [pkg] directory.
+
+If your favorite software is missing, keep in mind that you can
+still install it via pkgsrc or nix.
