-Runon is a frontend to podman allowing to run seamlessly any application in
-any linux based operating system, including graphical applications, while
-keeping the host user environment.
-
-the v1 legacy runon branch was based on docker. Current versions are now

-### Podman Install
+### Docker Install
 
-If not already installed, just run as root the suitable command for your system:
+    sudo apt install docker
+    sudo systemctl enable --now docker
 
-    apt install podman
-    dnf install podman
+Check that your are member of `docker` group:

-
-it's likely that your user account has been create a while ago on a legacy
-distribution release and has no support for `subuid` and `subgid`. You can
-fix it easily with these commands:
-
-    sudo usermod --add-subgids 10000-75535 $USER
-    sudo usermod --add-subuids 10000-75535 $USER
-    podman system migrate
-    podman pull
-
-If you're running on a Debian system, there is a good explanation of the above problem in `/usr/share/doc/podman/README.Debian`.
+If needed, you need to logout and login again for the new group to
+become active.
 
 ### Python Dependencies
 
-There is no specific dependency, you just need to insure to have:
-
-* a Python release 3.6 or better
-* the python `venv` module
-* the python `pip` module
-
+    sudo apt install python3-docker python3-dockerpty python3-xdg

-  default
+    cd <runon>
+    sudo ./install system
 
+each user can have its own configuration in `~/.config/runon/runon.conf`
+if needed.
 
 ### uninstall
 
-To uninstall, just run:
-
-    ./uninstall
+simply pass `-u` to install command you have used, eg.:
 
+    ./install local -u
+    ./install local -u <dir>
+    sudo ./install system -u
 
 ### some convenient links
 
 you can create soft links to `runos` to simplify calls:
 
-    runos -l centos7
+    runos centos7 -l
 
 now calling `centos7 ...` is equivalent to call `runos centos7 ...`:
