+# eu.ad5001.LogarithmPlotter
+
+Flahub repository for [LogarithmPlotter](https://apps.ad5001.eu/logarithmplotter).
+
+## Build
+
+You can build the latest version of LogarithmPlotter flatpak using `flatpak-builder`:    
+```bash
+flatpak-builder AppDir eu.ad5001.LogarithmPlotter.json
+```
+
+After it finishes building (note that this step can take a while as it compiles Qt), you can run it using:
+```bash
+flatpak-builder --run AppDir/ eu.ad5001.LogarithmPlotter.json logarithmplotter --no-check-for-updates
+```
