+# What is hasher?
+
+hasher is a tool for building packages in a safe and reproducible manner. All packages in [Sisyphus](https://en.altlinux.org/Sisyphus) repository are built using hasher.
+
+hasher is similar to earlier ApplianceWare/ALT Linux [sandman](http://old.linux.kiev.ua/~mike/docs/livecd/sandman_mini-howto.html), Debian [sbuild](http://packages.debian.org/sid/sbuild)/[pbuilder](http://www.netfort.gr.jp/~dancer/software/pbuilder-doc/pbuilder-doc.html) and also later Fedora [mock](http://fedoraproject.org/wiki/Projects/Mock), but unlike the mentioned tools it is designed and implemented with security in mind. hasher prevents interaction between package being built and host system and also between packages being built.
+
+It's included into [builder starterkit](https://en.altlinux.org/Starterkits/builder) ready-to-use.
+
