@ -32,17 +32,17 @@ Slic3r is able to:
* read binary and ASCII STL files;
* generate multiple perimeters (skins);
* generate rectilinear feed (100% solid for external surfaces or with customizable less density for inner surfaces);
* generate rectilinear fill (100% solid for external surfaces or with customizable less density for inner surfaces);
* use relative or absolute extrusion commands;
* center print around bed center point;
* use different speed for bottom layer;
* output relevant GCODE.
Roadmap include the following goals:
Roadmap includes the following goals:
* set up a command line interface and hide debug messages;
* output some statistics;
* allow the user to customize initial and final GCODE commands;
* retraction;
* option for filling multiple solid layers near external surfaces;
* support material for internal perimeters;
* ability to infill in the direction of bridges;

## Is it usable already?
Not yet, as I need to finish the command line interface.
Yes. I need to write a script to install dependencies.
## Can I help?
