+# Podterminal
+
+This project is a small go reverse proxy that spins up a container for each session, allowing multiple simultaneous
+Users to use Webtop in their own, separate session. A good illustration is this:
+![Webtop Inception](doc/podterminal_inception.png)
+
+## Building
+To build the project, you can just use "make"
+
+## Running
+To run the built binary, just execute it as root. You will have to have Podman installed and its socket enabled.
+Currently you have to set the Image, port etc. directly in the Source Code, however that should be eventually moved into
+a config file.
