+The normal way of installing is to run ./RPi_Cam_Web_Interface_Installer.sh
+This remains the case.
+
+There are now some experimental scripts, which have not been fully proven and are still being developed,
+but you are welcome to try out.
+The main install seems to work for me on Jessie. Not tried on Wheezy yet but in principle it should work.
+
+The scripts are a re-factoring of the install scripts to simplify the process.
+
+5 scripts are used instead of combining all together.
+This avoids the overhead of a separate selection and makes it easier to run a particular function automatically.
+So start and stop can just be run as separate activities.
+
+The scripts are
+install.sh main installation
+upgrade.sh check for updates and then run main installation
+start.sh starts the software
+stop.sh stops the software
+remove.sh removes the software
+
+The main installation always does the same thing to simplify its logic.
+It gathers all user parameters first in one combined dialog and then always
+applies the parameters as it goes through the process.
+A q (quiet) parameter may be used to skip this and give an automatic install based on config.txt
+All parameters are always in the config.txt file, a default version is created if one
+doesn't exist and is then changed just once after the initial user dialog.
+The installation always tries to upgrade the main software components and then functionally goes through
+the configuration steps for each area like apache, motion start up.
+
+Debug is turned on for th emoment so it logs its activity to a file called install.txt
