+
+## installation
+
+Firstly [download](https://gitlab.constantvzw.org/osp/tools.cobbled-paths/-/archive/master/tools.cobbled-paths-master.zip) this repository, or clone it: `git clone git@gitlab.constantvzw.org:osp/tools.cobbled-paths.git`
+
+### Python
+
+The interface uses python and require python 3, find information on how to [install python here](https://www.python.org/downloads/)

+
+Then `cargo install svgbob_cli`
+
+### vpype
+
+Installation of vpype is optional. It is used to convert the SVG files to HPGL.
+
+Please follow the [installation instructions](https://github.com/abey79/vpype#installation)

 ## font database
 
 * figlet offical ftp at <ftp://ftp.figlet.org>
-  * `ours` the original default font made by the developper and given with the program, in early 1993
+  * `ours` the original default font made by the developer and given with the program, in early 1993
   * `contributed` fonts made by figlet amateur and submitted to the official figlet ftp, from before 1993 to 2005
     * `c64` are fonts that are only made of the `#` character, the most black ascii char, is if it was a pixel
     * `bdffont` are fonts automatically made using bdf2figlet, converting [Glyph Bitmap Distribution Format](https://en.wikipedia.org/wiki/Glyph_Bitmap_Distribution_Format), often from adobe to `c64` like font.
