+$ sudo apt update
+$ sudo apt install \
+    gdal-bin \
+    jq \
+    libimage-exiftool-perl \
+    libtiff-tools \
+    python3-pip \
+    python3-virtualenv
+
+$ virtualenv ~/.geotiffs
+$ source ~/.geotiffs/bin/activate
+
+$ git clone https://github.com/marklit/geotiffs ~/geotiffs
+$ python -m pip install -r ~/geotiffs/requirements.txt
+```

+    virtualenv
+
+$ virtualenv ~/.geotiffs
+$ source ~/.geotiffs/bin/activate
+
+$ git clone https://github.com/marklit/geotiffs ~/geotiffs
+$ python -m pip install -r ~/geotiffs/requirements.txt
+```
+
