When running `cabal build`, I ran into this issue:
```
Warning: The package list for 'hackage.haskell.org' does not exist. Run 'cabal
update' to download it.RemoteRepo {remoteRepoName = RepoName

Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] trying: byron-spec-chain-0.1.0.0 (user goal)
[__1] unknown package: microlens-th (dependency of byron-spec-chain)
[__1] fail (backjumping, conflict set: byron-spec-chain, microlens-th)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: byron-spec-chain, microlens-th
```
As described, I needed to run `cabal update` first. It could be helpful to have it in the README to help some people get started

- Build the [English Auction ](code/week01 ) contract with `cabal build` (you may need to run `cabal update` first).
2021-04-08 12:15:17 +02:00
- Clone the [The Plutus repository ](https://github.com/input-output-hk/plutus ), check out the correct commit
as specified in [cabal.project ](code/week01/cabal.project ).

- Set-up IOHK binary caches [How to set up the IOHK binary caches ](https://github.com/input-output-hk/plutus#iohk-binary-cache ). "If you do not do this, you will end up building GHC, which takes several hours. If you find yourself building GHC, STOP and fix the cache."

- Enter a `nix-shell` .
- Go to the `plutus-playground-client` folder.
- Start the Playground server with `plutus-playground-server` .
- Start the Playground client (in another `nix-shell` ) with `npm run start` .
- Copy-paste the auction contract into the Playground editor - don't forget to remove the module header!
- Compile.
- Simulate various auction scenarios.

## Some Plutus Modules
- [`PlutusTx.Data` ](https://github.com/input-output-hk/plutus/blob/master/plutus-tx/src/PlutusTx/Data.hs ), contains the definition of the `Data` type.
2021-04-12 22:59:51 +02:00
- [`PlutusTx.IsData.Class` ](https://github.com/input-output-hk/plutus/blob/master/plutus-tx/src/PlutusTx/IsData/Class.hs ), defines the `IsData` class.
