## Configuration
::: incremental
* Types of configuration:
- environment variables
- cli switches / TUI options
- config file (`~/.ghcup/config.yaml`)
* e.g.
- env: `GHCUP_INSTALL_BASE_PREFIX` (default `$HOME`)
- cli: `ghcup install ghc -u <url> <version>`
- config: `url-source` (selecting and mixing "channels")
- file/http/https URI
- `GHCupURL`
- `StackSetupURL`

# Contributing
## How to contribute
**Some live action:**
- project structure
- building the project (flags and project files)
- small code walkthrough
## The future
::: incremental
- nightlies
- revisions
- curating old releases
- beefed up `ghcup compile` interface
- TUF?
- supporting more tools (installer DSL)
:::
## Advanced topics
- bootstrap scripts
- windows and MSYS2
- security
- HLS/GHC interaction
- reproducibility
- stack integration
- bindist work (curation)
- isolated installs
- mirrors
## Cool things to contribute to
- documentation
- discussions
- deciding on defaults (metadata etc.)
- API for e.g. stack
- Dhall
- manpage (via [optparse-applicative](https://github.com/pcapriotti/optparse-applicative/issues/176)?)
- TUI (@lsmor)
- YAML schema for metadata
- integration test
- cross compiler support
- nightlies
- "health check" command
