  21 Ways to get the `cabal-install` binary
  22 --------------------------------
  23
  24 1. _GHCup (**preferred**)_: get GHCup using [the directions on its website](https://www.haskell.org/ghcup/) and run:
  25
  26     ```
  27     ghcup install --set cabal latest
  28     ```
  29
  30 2. _[Download from official website](https://www.haskell.org/cabal/download.html)_:
  31     the `cabal-install` binary download for your platform should contain the `cabal` executable.
  32
  33 _Getting unreleased versions of `cabal-install`_: gives you a chance to try out yet-unreleased features.
  34 Currently, we only provide binaries for `x86_64` platforms.
  35
  36 1. _[GitHub preview release built from the tip of the `master` branch](https://github.com/haskell/cabal/releases/tag/cabal-head)_:
  37
  38 2. Even more cutting-edge binaries built from pull requests are always available
  39    from the `Validate` worklow page on GitHub, at the very bottom of the page.

  41 Ways to build `cabal-install` for everyday use
  42 --------------------------------------------
  43
  44 1. _With cabal-install_:
  45     if you have a pre-existing version of `cabal-install`, run:
  46
  47     ```
  48     cabal install cabal-install
  49     ```
  50
  51     to get the latest version of `cabal-install`. (You may want to `cabal update` first.)
  52
  53 2. _From Git_:
  54     again with a pre-existing version of `cabal-install`,
  55     you can install the latest version from the Git repository. Clone the
  56     Git repository, move to its root, and run:
  57
  58     ```
  59     cabal install --project-file=cabal.project.release cabal-install
  60     ```
  61
  62 3. _Bootstrapping_:
  63     if you don't have a pre-existing version of `cabal-install`,
  64     look into the [`bootstrap`](bootstrap) directory.
  65
  66 Build for hacking and contributing to cabal
