## Basics
### Setup
We use [Cabal](https://cabal.readthedocs.io/) to build the project.
We use the [`cabal`](https://cabal.readthedocs.io/) command line tool to build
the project. The best way to install it is via
[ghcup](https://www.haskell.org/ghcup/). The `ghcup tui` terminal user interface
is a convenient way of installing and selecting versions of `cabal`, `hls` and
`ghc`.
The best way to install it is via [ghcup](https://www.haskell.org/ghcup/).
In [cabal.project](cabal.project) we're explicitly saying what compiler version
to build Wasp with.
Check [cabal.project](cabal.project) for exact version of GHC that we use to build Wasp.
Then, ensure via `ghcup` that you use that version of GHC and that you are using corresponding versions of `cabal` and `hls`.
```cabal
with-compiler: ghc-x.y.z
```
Ensure that you have this [ghc
version](https://downloads.haskell.org/ghc/latest/docs/html/users_guide/intro.html#ghc-version-numbering-policy)
installed.
