+# Notes for test users of HUB TimeSeriesViewer (TSV)
+
+1. Ensure that git is installed on your system.
+
+    C:\Windows\system32>git
+
+
+should produce a meaningful output.
+
+If not existing, download git from:
+
+    [git download](https://git-scm.com/download)
+
+
+2. Create your personal "QGIS_Plugin" folder.
+
+3. Clone the repository into the QGIS_Plugin folder and checkout the qgis_api branch by:
+
+        git clone https://bitbucket.org/jakimowb/hub-timeseriesviewer.git
+        cd hub-timeseriesviewer
+        git fetch && git checkout qgis_api
+
+   The source code of the qgis_api branch should now appear in QGIS_Plugin/hub-timeseriesviewer.
+
+4. Tell QGIS where to find this folder by adding QGIS_Plugin to the QGIS_PLUGINPATH variable.
+Create it variable in case it does not exist.

+
+        git pull
+
+to get updates from the remote branch. Then restart QGIS.
