what a coincidence!! this big achievement is the 800th commit!!

 `tools/debug.sh` will run Luna in QEMU with a port open for GDB to connect to. (run `tools/build-debug.sh`, `tools/gdb.sh`, and then `tools/debug.sh` in a separate terminal for an optimal debugging experience)
 
-Beware that running without hardware virtualization/with optimizations disabled may cause the kernel to behave differently, which is why I don't use it that often.
+Beware that running with optimizations disabled may cause the kernel to behave differently, which is why I don't use it that often.
 
 Essentially, since `run.sh` builds the toolchain if it hasn't been built, builds Luna if it hasn't been built, and runs it, you could just checkout this repo, run `run.sh`, and you're done. No need for the other scripts. Those are included for more fine-grained control/building step-by-step.

 ## Is there third-party software I can use on Luna?
 
 Yes, actually! Check out the [ports](ports/) directory.
-Right now, there are very few ports, because our C Library is quite primitive and doesn't support complex projects. 
+Right now, there are very few ports, because our C Library is a bit primitive and doesn't support complex projects.
-I'm in the process of trying to port the [GNU binutils](https://www.gnu.org/software/binutils/), though.

+You should also keep in mind that it is not possible to compile software written in any language other than C/C++ (and C++ was added recently, its standard library doesn't work very well) for Luna right now.
 
 But feel free to try to port some program yourself and add it to the ports directory!
