### Fork Lean on github : https://github.com/leanprover/lean2

### Create a projects directory

    cd ~
    mkdir projects
    cd projects

### Clone your fork

    git clone https://github.com/[your-user-name]/lean2.git

### Build Lean in release mode

    cd lean2
    mkdir -p build
    cd build
    cmake -D CMAKE_BUILD_TYPE=Release ../src
    make

### Alternative ways to build
Using Ninja (to speed up build)

    cmake -DCMAKE_BUILD_TYPE=RELEASE -G Ninja ../src
    ninja

Using Boost (to speed up build)

    cmake -D CMAKE_BUILD_TYPE=Release -D BOOST=ON ../src
    make

Build in debug mode

    cmake -DCMAKE_BUILD_TYPE=DEBUG ../src
    make
 
### You need to also set up the [Emacs Mode](../../src/emacs/README.md).
