-requirements
-============
-
-to be able to generate the outputs you need following software:
-- rake: the central script taking care of generating the output files (Makefile is too cumbersome to parse files)
-- [QEDA](http://qeda.org/): to generate footprints for the parts
-- [Lepton EDA](https://github.com/lepton-eda/lepton-eda): for the schematic capture
-- [pcb-rnd](http://repo.hu/projects/pcb-rnd/): for the board layout
-the output generation is automatized.
-
-schematic
-=========
-
-library
--------
-
-almost all of the symbols and footprints used in the schematic and board layout are defined in the [QEDA](http://qeda.org/) format and generated for the CAD software.
-the `library` folder contains the QEDA parts definitions.
-
-to install QEDA using NPM from the official repository:
-~~~
-sudo npm install -g qeda
-~~~
-
-to install QEDA from the sources:
-~~~
-git clone https://github.com/qeda/qeda
-cd qeda
-npm install
-sudo npm install --global
-~~~
-
-to generate the parts:
-~~~
-rake library
-~~~
-
-this will use the parts definition (.yaml files) in the `library` to generate [gEDA gschem](http://wiki.geda-project.org/geda:gaf)/[Lepton EDA](https://github.com/lepton-eda/lepton-eda) symbols (.sym files) in the `geda/symbols` folder, and [coralEDA pcb-rnd](http://repo.hu/projects/pcb-rnd/) footprints (.lht files) in the `coraleda/subc` folder.
-
-only the QEDA parts in subfolders within `library` come from the [QEDA library](https://doc.qeda.org/library/), but the files are included in this project for simplicity and archiving purposes.
-all other parts are custom and written for this project.
-
-schematic
----------
-
-the `.sch` file is the schematic source file.
-it has been drawn using [Lepton EDA](https://github.com/lepton-eda/lepton-eda).
-
-it uses standard symbols, and the ones in the `geda/symbols/` folder.
-most symbols are generated by QEDA as described above.
-
-to export the netlist (in tEDAx format):
-~~~
-rake netlist
-~~~
-
-to export as pdf:
-~~~
-rake print
-~~~
-
-BOM
----
-
-to export the bill of material (as CSV):
-~~~
-rake bom
-~~~
-
-board
-=====
-
-the `.lht` file is the board layout source file.
-it has been drawn using  [coralEDA pcb-rnd](http://repo.hu/projects/pcb-rnd/).
-
-it uses the symbols from the `coraleda/subc/` folder.
-most symbols are generated by QEDA as described above.
-`oshw_logo.lht` is just the Open Source Hardware Logo.
-it been generated from https://oshwlogo.cuvoodoo.info/.
-
-to export gerber files for PCB manufacturer (and photo preview + overview document):
-~~~
-rake fabrication
-~~~
+the JSON files are the source schematic and board layout made using [EasyEDA](https://easyeda.com/).
