+# GDS-Render
+
+This software is a rendering programm for GDS2 layout files.
+The GDS2 format is mainly used in integrated circuit development.
+This program allows the conversion of a GDS file to a vector graphics file.
+
+## Output Formats
+* Export GDS Layout to LaTeX (using TikZ).
+* Export to PDF (Cairographics).
+
+# Features
+Note: Due to various size limitations of both TikZ and the PDF export, the layout might not render correctly. In this case adjust the scale value. A higher scale value scales down your design.
+
+* Configurable layer stack-up.
+* Layer colors configurable as ARGB color values.
+* Command line interface.
+* ~~Awesome~~ Somehow usable GUI.
+
+# License and Other Stuff
+* Free software (GPLv2 _only_)
+* Coded in plain C using GTK+3.0, Glib2, and Cairographics
