+# `ppppcg`
+
+A [PrePostPrint](https://prepostprint.org) inspired political compass generator with SVG output.
+
+Why? You may find some answers on [here](http://blog.osp.kitchen) or [there](https://pad.vvvvvvaria.org/PPP-local-meetup).
+
+<p align="center">
+  <img src="./ppppcg.png" />
+</p>
+
+## Install
+
+### Linux
+
+```
+curl https://git.coopcloud.tech/decentral1se/ppppcg/raw/branch/main/dist/ppppcg_linux_amd64_v1/ppppcg -o ppppcg
+chmod +x ppppcg
+```
+
+### MacOS
+
+```
+curl https://git.coopcloud.tech/decentral1se/ppppcg/raw/branch/main/dist/ppppcg_darwin_amd64_v1/ppppcg -o ppppcg
+chmod +x ppppcg
+```
+
+## Usage
+
+Wire up a config file (`ppppcg.yml`).
+
+```yaml
+width: 500
+height: 500
+
+axis:
+  top: W3C
+  right: Industry
+  bottom: Custom hacks
+  left: Punk
+
+points:
+  - {name: "???", x: 50, y: 450}
+```
+
+And generate the SVG like so.
+
+```
+./ppppcg
+```
+
+You can pipe it to a graphical program or save it to file.
+
+```
+./ppppcg | display # X11 viewer
+./ppppcg > pc.svg  # to file
+```
