+# fish : Fabulously Irrespectuous SHell
+
+fish is a student project, aiming to be a basic interactive shell for linux.
+
+
+## Warnings
+
+fish is really an IRRESPECTUOUS shell. Now that you're warned...
+
+
+## Features
+
+fish reads from standard input and send you the result of every command on standard output ( unless you redirect I/O ). Aside of that, fish also implements various features :
+
+* **Internal commands** : change of directory, exiting, help.
+* **External commands** : fish will execute any command you ask, provided he can find those in his PATH variable.
+* **Insults** : fish will yell at you whenever you make a mistake to make sure you never fail again.
+* **Configuration file** : .fishrc file for easy configuration ( path, prompt.. ).
+* **Globbing** : fish implements a globbing feature, handling characters such as \*, ? and ( soon ) ~.
+* **Operators** : fish comes with some operators support : **&&** and **||**. 
+* **I/O redirections** : coming soon ( TM )
+
+
+everything without a single memory leak ! ( if you find one tell us )
+
+
+## License
+
+fish is licensed under the GPLv3 license.
+
+
+## About us
+
+We're 3 students in CS, and this was one of our project.
+
+* Klmp200/Sli : Works for google in another dimension.
+* Aethor/Bro : Not even a saint in the church of Emacs.
+* Ame : The silent game master.
