Thanks for the delivery, @feliam. I am going through the instructions in the readme, and I keep running into this error below. Any idea what I might be missing?

Hi @semuelle,

The issue with th build is likely due to a problem with how Rust is resolving the contract-transcode crate included in the drink crate. Please try building with the locked flag:

cargo build --release --locked

Also, please make sure you are working on the milestone-1 branch, as the develop branch is currently under active development and may not be in a stable state.

Let us know if this resolves the problem or if you have any other questions

[semuelle]

Thanks for the clarification, @feliam. I hadn't noticed the milestone-1 branch. Everything is compiling and running now, thanks. Your milestone is hereby accepted. You can find my evaluation notes here.
