  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_: [download from GitHub](https://github.com/haskell/cabal/releases/tag/cabal-head) or use this GHCup command to install:
  37
  38     ```
  39     ghcup install cabal -u https://github.com/haskell/cabal/releases/download/cabal-head/cabal-head-Linux-x86_64.tar.gz head
  40     ```
  41
  42     Replace "Linux" with "Windows" or "macOS" as appropriate.
  43
  44
  45 2. Even more cutting-edge binaries built from pull requests are always available
  46    from the `Validate` worklow page on GitHub, at the very bottom of the page.
  47
  48 Ways to build `cabal-install` for everyday use
  49 --------------------------------------------
  50
  51 1. _With cabal-install_:
  52     if you have a pre-existing version of `cabal-install`, run:
  53
  54     ```
  55     cabal install cabal-install
  56     ```
  57
  58     to get the latest version of `cabal-install`. (You may want to `cabal update` first.)
  59
  60 2. _From Git_:
  61     again with a pre-existing version of `cabal-install`,
  62     you can install the latest version from the Git repository. Clone the
  63     Git repository, move to its root, and run:
  64
  65     ```
  66     cabal install --project-file=cabal.project.release cabal-install
  67     ```
  68
  69 3. _Bootstrapping_:
  70     if you don't have a pre-existing version of `cabal-install`,
  71     look into the [`bootstrap`](bootstrap) directory.
