-From here, you will be put in a shell suited for development. If your editor has LSP support with clangd (e.g. neovim, emacs, VSCode, Zed), you will get proper goto-declarations and warnings. You can quickly rebuild the kernel library from here with `cmake -B build && (cd build; make)`, with all build dependencies handled by the shell. You can also build and run a unikernel from the shell with this oneliner: `(cd ./example && cmake -B build && (cd build && make) && boot ./build/hello_includeos.elf.bin)` after building IncludeOS. It might be convenient to use one terminal (or tab) for your editor, a second for building IncludeOS, and a third for building a unikernel.

 In summary:
 ```bash

-[nix-shell:~/repos/IncludeOS]$ cmake -B build && (cd build; make) # rebuilds IncludeOS
-[nix-shell:~/repos/IncludeOS]$ cd example
-[nix-shell:~/repos/IncludeOS/example]$ cmake -B build && (cd build; make) # rebuilds a bootable unikernel
-[nix-shell:~/repos/IncludeOS/example]$ boot ./build/hello_includeos.elf.bin # runs the unikernel image with qemu through vmrunner
+[nix-shell:~/repos/IncludeOS]$ cmake -B build && cmake --build build # rebuilds IncludeOS

+[nix-shell:~/repos/IncludeOS]$ boot ./result/hello_includeos.elf.bin # runs the unikernel image with qemu through vmrunner
 ```
 
 Alternatively, you may want to use `nix-shell` by itself (or nested inside the development shell), which handles both building the unikernel found under `./example/` and puts you in a convenient shell for testing out a unikernel.
 
 ```bash
-~/repos/IncludeOS $ nix-shell --run 'boot hello_includeos.elf.bin'
+# both these require vmrunner's booth on path
+~/repos/IncludeOS $ nix-shell unikernel.nix --run 'boot hello_includeos.elf.bin'
 # or
-~/repos/IncludeOS $ nix-shell  # updating IncludeOS after entering this shell won't rebuild the os library automatically!
-[nix-shell:~/repos/IncludeOS]$ boot hello_includeos.elf.bin
+~/repos/IncludeOS $ nix-shell unikernel.nix
+[nix-shell:~/repos/IncludeOS/result]$ boot hello_includeos.elf.bin
 ```
 
 If you want to build a different unikernel than the example, this can be specified with the `--argstr unikernel [path]` parameter. This is primarily used for integration tests. For example, to build and run the stacktrace-test:
 
 ```bash
-$ nix-shell --argstr unikernel ./test/kernel/integration/stacktrace

-You can run all the integration tests using the script `./test.sh`. The tests will run locally in the nix environment. We recommend manually verifying that all the tests pass locally before submitting a new PR to IncludeOS to save review time.
