+snapz - Snaps STL files to zero Z coordinate
+============================================
+
+STL files sliced with Skeinforge are not snapped to zero Z coordinate automatically.
+This could lead to various errors while printing and you have to be sure to snap the STL object to Z = 0.
+While there are GUI tools that can do that, snapz aims for command line utility.
+
+Compile
+-------
+
+To compile snapz, you'll need the [admesh library](https://github.com/hroncok/admesh), gcc and make. Then just type `make` to compile it.
+
+Install
+-------
+
+You don't need to install snapz, you can invoke it from where it is with `./snapz`. However, to make things easier, it is recommended to put it somewhere in your `$PATH` (e.g. `/usr/local/bin`).
+
+Run
+---
+
+To snap an STL file to Z = 0, run:
+
+    snapz file.stl
+
+If you want to keep the input and save the snapped STL to a different file, you can do it this way:
+
+    snapz input.stl output.stl
+
+If `output.stl` exists, it will be overwritten without questions, cause you know, what are you doing, right?
+
+License
+-------
+
+This app and it's docs are released under the terms of WTFPL. That means you just do what the fuck you want to.
