+# Tui-Website
+
+This is my terminal based website. It is served as a tui application via ssh and as a simple html page via https.
+
+It contains information about me and my projects as well as blog entries about something I feel like writing something about.
+
+## Open tasks
+
+- [ ] BUG: when served via `wish-serve` the corresponding outputs are not pushed through the ssh connection
+ - they are instead showed locally, which might cause issues with the docker container running in the background
+ - very likely it is `tui-website` which causes this issue
+ - not entirely as inputs are not passed through correctly to the below running application (i.e. `diffnav` via `serve git diff`)
+- [ ] Improve navigation
+- [ ] Have clickable/navigatable links inside of the tui application
+- [ ] Launch simple http server alongside tui application
