-# ALF Tutorial
-This is a tutorial for using ALF intended to get you started from zero up to your own first 
-projects.
-
-## Installation.
-**ALF** is pretty self-contained, you only need a LAPACK and a BLAS implementation
-as external libraries. For compiling the source code you need make and a
-Fortran 2003 compatible Compiler.
-
-**pyALF**, the Python interface for ALF, also demands only Python, Jupiter and a few basic Python packages: SciPy, NumPy and matplotlib.
-
-Python and its packages can be easily installed on a variety of platforms using the Anaconda distribution -- check its [installation instructions](https://docs.anaconda.com/anaconda/install/) for your system. Then, from Anaconda, all that is needed is to issue the command
-```bash
-conda install -c anaconda  ipython jupyterlab scipy numpy matplotlib
-```
-Anaconda is recommended due to its convenience, but the system's package management (e.g., apt-get) or Python's own package management, pip3, can be used instead if preferred.
-
-### Linux
-In the following we give hints on how to install relevant ALF packages.
-
-- **Debian/Ubuntu/Linux Mint**:  `sudo apt-get install gfortran liblapack-dev make`
-- **Red Hat/Fedora/CentOS**:  `sudo yum install gcc-gfortran make liblapack-devel`
-- **OpenSuSE/SLES**:  `sudo zypper install gcc-gfortran make lapack-devel`
-- **Arch Linux**:  `pacman -S make gcc-fortran lapack`
-
-### Other Unixes
-gfortran and the lapack implementation from netlib.org should be available for
-your system. Consult the documentation of your system on how to install the
-relevant packages. The package names from linux should give good starting points
-for your search.
-
-### MacOS
-gfortran for MacOS can be found at https://gcc.gnu.org/wiki/GFortranBinaries#MacOS.
-Detailed information on how to install the package  can be found at: https://gcc.gnu.org/wiki/GFortranBinariesMacOS.
-You will need to have Xcode as well as the  Apple developer tools installed. 
-
-### Windows
-The easiest way to compile Fortran code in Windows is trough Cygwin, which 
-provides a Unix-like environment for Windows. The installer also works as a 
-package manager, providing an extensive collection of software from the Unix 
-ecosystem. For convenience, we provide a zip archive containing the Cywin
-installer and a local repository with all the additional software needed for 
-ALF. 
-
-Steps for installing Cygwin:
-- Download zip from https://www.dropbox.com/s/ap8vl85gn9nfbo7/cygwin_ALF.zip?dl=0
-and unzip
-- Execute "setup-x86_64.exe". If administrator rights are missing, execute it 
-from the command line as "setup-x86.exe --no-admin".
-- In the setup choose "Install from local directory" instead of "Install from Internet".
-- Choose root directory, where cygwin will be installed. You should memorize this diretory.
-- Choose the diretory "cygwin\_ALF" (The one which also contains "setup-x86_64.exe") 
-as local package Directory.
-- At the "Select Packages" screen, in "Categories" view, at the line marked 
-"All", click on the word "default" so that it changes to "install".
-- Finish installation
-- Optional: To add, remove or update installed packages, rerun the installer 
-setup and chose "Install from Internet".
-- You can now use the installed Cygwin packages by starting the Cygwin terminal.
-It is a UNIX terminal which, by default, starts in the home diretory 
-"/home/<username>" of the UNIX-system emulated by Cygwin, where "/" is the root 
-directory of Cygwin. For example, if you have installed Cygwin in 
-"C:\cygwin64\", then the home Directory of Cygwin ca be found at 
-"C:\cygwin64\home\<username>", in the Windows system.
-
-## Building
-After you have obtained the source code and have set up the build environment
-you need to build the source files. Executing make in the root directory of ALF
-does the Job.
-
-## Editors
-For the coding parts of the exercises we recommend to use a text editor. 
-Linux usually have one installed like kwrite, kate or gedit(emacs and VI work
-great, too). For the windows users we recommend Notepad++.
