+
+## About The Project
+
+The main purpose of this project is a curiosity in system programming. I was using such shell giants as zsh and fish
+with abnormal amount of features. So I decided to deep dive on this topic. As the result Kara was born, minimalistic
+usable Linux shell.
+
+### Implemented Features
+
+- execution of different programs
+- two builtin commands: <code>cd</code>, <code>exit</code>
+- redirecting keyboard signals such as <code>^C</code> to current execution processes instead of shell
+- I/O redirecting via <code><</code>, <code>></code> and <code>2></code> for programs
+- piping via <code>|</code> symbol
+- expansion <code>~</code> to home directory path
+- reading environment variables with <code>$</code> symbol (<code>echo $USER</code> will print current user instead of
+  $USER)
+- commands history and input processing with emacs bindings are implemented with GNU readline library
+
+## Getting Started
+
+Kara is Linux shell, and I didn't try to run in on macOS or FreeBSD, but you free to do it and leave messages in the
+issues section.
+
+### Dependencies
+
+Kara depends on the GNU readline library. I suspect that any version is fine. Also, you'll need git, gcc and make,
+which are preinstalled on most Linux distributions.
+
+**Ubuntu:**
+
+``` shell
+sudo apt install libreadline-dev
+```
+
+**Fedora:**
+
+``` shell
+sudo dnf install readline readline-devel
+```
+
+**Arch:**
+
+``` shell
+sudo pacman -S readline
+```
+
+### Installing
+
+``` shell
+git clone https://github.com/amaom1/karashi.git
+cd karashi
+make && sudo make install
+```
+
+### Uninstalling
+
+In karashi directory enter that command:
+
+``` shell
+sudo make uninstall
+```
+
+Now Kara is not installed in your $PATH and you free to delete repository too.
+
+### Tests
+
+Kara provides some kind of overview of what it is capable of. To run it just enter that command after building project:
+
+``` shell
+make test
+```
+
+### Documentation
+
+Kara provides auto-generated documentation via Doxygen. If you are interested in the project structure but don't want
+to view the source code, you can check out the documentation on the [GitHub pages](https://amateomi.github.io/karashi/html/index.html).
