# Serenity

Graphical Unix-like operating system for x86 computers.

![Travis CI status](https://api.travis-ci.com/SerenityOS/serenity.svg?branch=master)

## About

*I always wondered what it would be like to write my own operating system, but I never took it seriously. Until now.*

Serenity is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s \*nix. This is a system by me, for me, based on the things I like.

If you like some of the same things, you are welcome to join the project. It would be great to one day change the above to say "this is a system by us, for us, based on the things we like." :^)

I regularly post raw hacking sessions and demos on [my YouTube channel](https://www.youtube.com/c/AndreasKling/).

Sometimes I write about about the system on [my github.io blog](https://awesomekling.github.io/).

There's also a [Patreon](https://www.patreon.com/serenityos) if you would like to show some support that way.

## How do I build and run this?

Make sure you have all the dependencies installed:

```
sudo apt install libmpfr-dev libmpc-dev libgmp-dev e2fsprogs qemu-system-i386 qemu-utils
```

Go into the `Toolchain/` directory and run the **BuildIt.sh** script. Then ***source*** the **UseIt.sh** script to put the `i686-pc-serenity` toolchain in your `$PATH`.

Once you've done both of those, go into the `Kernel/` directory, then run
**./makeall.sh**, and if nothing breaks too much, take it for a spin by using
**./run**.

Later on, when you `git pull` to get the latest changes, there's no need to rebuild the toolchain. You can simply rerun **./makeall.sh** in the `Kernel/` directory and you'll be good to **./run** again.
