+# ALBase
+
+This is an experimental Linux distro with a focus on simplicity and efficiency.
+The goals of the project are as follows:
+
+* No dynamically linked executables in the base
+* Link against musl instead of glibc
+* No systemd or any of it's components
+* No DBus or any of it's components
+* As little GNU code as possible
+
+## Building
+
+    # Optional: build the musl-based cross compiler and use that for the build
+    ./bootstrap.sh
+    make stage1
