 # `Akantu`: Swiss-Made Open-Source Finite-Element Library
 
 `Akantu` means a little element in Kinyarwanda, a Bantu language. From now on it
 is also an open- source object-oriented library which has the ambi- tion to be
 generic and efficient.
 
 # Building `Akantu`
 
 ## Dependencies
 
 In order to compile `Akantu`  any compiler supporting fully C++14 should work.
 In addition some libraries are required:
 
  - CMake (>= 3.5.1)
  - Boost (preprocessor and Spirit)
  - zlib
  - blas/lapack
 
 For the python interface:
 
  - Python (>=3 is recommended)
  - pybind11 (if not present the build system will try to download it)
 
 To run parallel simulations:
 
  - MPI
  - Scotch
 
 To use the static or implicit dynamic solvers at least one of the following libraries is needed:
 
  - MUMPS (since this is usually compiled in static you also need MUMPS dependencies)
  - PETSc
 
 To compile the tests and examples:
 
  - Gmsh
  - google-test (if not present the build system will try to download it)
 
 ### On `.deb` based systems
 
 ``` sh
-> sudo apt install cmake libboost-dev zlib-dev liblapack-dev libblas-dev gmsh
+> sudo apt install cmake libboost-dev zlib1g-dev liblapack-dev libblas-dev gmsh
 # For parallel
 > sudo apt install mpi-default-dev libmumps-dev 
 # For sequential
 > sudo apt install libmumps-seq-dev 
 ```
 
 ## Configuring and compilation
 
 
 `Akantu` is a [CMake](https://cmake.org/) project, so to configure it, you can follow the usual way:
 
 ``` sh
   > cd akantu
   > mkdir build
   > cd build
   > ccmake ..
   [ Set the options that you need ]
   > make
   > make install
 
 ```
 
 ## Using the python interface
 
 
 You can install ``Akantu`` using pip, this will install a pre-compiled version:
 
 ``` sh
   > pip install akantu
 ```
 
 You can then import the package in a python script as:
 
 ``` python
   import akantu
 ```
 
 The python API is similar to the C++ one. If you
 encounter any problem with the python interface, you are welcome to do a merge
 request or post an issue on [GitLab](https://gitlab.com/akantu/akantu/-/issues).
   
 # Tutorials with the python interface
 
 To help getting started, multiple tutorials using the python interface are
 available as notebooks with pre-installed version of `Akantu` on Binder. The
 following tutorials are currently available:
