+#### **Debian/Ubuntu and Docker**
+
+In many cases I2P will be running as the Debian system user ```i2psvc```. This
+is the case for all installs where Debian's Advanced Packaging Tool(apt) was
+used to peform the task. If you used ```apt-get install``` this command will
+work for you. In that case, just copy-and-paste:
+
+        docker run -itd \
+            --name reseed \
+            --user $(id -u i2psvc) \
+            --group-add $(id -g i2psvc) \
