-### Testing Hermit apps using `cargo run`
-
-As mentioned above, the Uhyve repository ships some binaries that can be used for testing purposes.
-
-```sh
-cargo run -- data/x86_64/rusty_demo
-cargo run -- data/x86_64/hello_world
-cargo run -- data/x86_64/hello_c
-```
-
-### Debugging Hermit apps
-
-Basic support of (single-core) applications is already integrated into Uhyve.
-
-By specifying variable `HERMIT_GDB_PORT=port`, Uhyve is working as gdbserver and is waiting on port `port` for a connection to a gdb.
-For instance, with the following command Uhyve is waiting on port `6677` for a connection.
-
-```bash
-HERMIT_GDB_PORT=6677 uhyve /path_to_the_unikernel/hello_world
-```
-
-In principle, every gdb-capable IDE should be able to debug Hermit applications. (Eclipse, VSCode, ...)
-
-#### Visual Studio Code / VSCodium
-
-The repository [hermit-rs](https://github.com/hermit-os/hermit-rs) provides [example configuration files](https://github.com/hermit-os/hermit-rs/tree/master/.vscode) to debug a Hermit application with [Visual Studio Code](https://code.visualstudio.com/), [VSCodium](https://vscodium.com/) or derivatives of [Eclipse Theia](https://theia-ide.org/).
