Installing Cabal (by downloading the binary)
--------------------------------------------

Prebuilt binary releases can be obtained from https://www.haskell.org/cabal/download.html.
The `cabal-install` binary download for your platform should contain the `cabal` executable.

Installing Cabal (with cabal)
-----------------------------

Assuming that you have a pre-existing, older version of `cabal-install`,
run:

~~~~
cabal install cabal-install
~~~~

To get the latest version of `cabal-install`. (You may want to `cabal
update` first.)

To install the latest version from the Git repository, clone the
Git repository and then run:

~~~~
(cd Cabal; cabal install)
(cd cabal-install; cabal install)
~~~~

Installing Cabal (without cabal)
--------------------------------

Assuming you don't have a pre-existing copy of `cabal-install`, run:

~~~~
cabal-install $ ./bootstrap.sh # running ./bootstrap.sh from within in cabal-install folder.
~~~~

For more details, and non-unix like systems, see the [README.md in cabal-install](cabal-install/README.md) and [Contributing Guidelines](CONTRIBUTING.md).
