Get a copy of the project and go to its root directory such that its `shard.lock` file is in the current directory. Executable projects should usually commit the `shard.lock` file, but sometimes that's not the case, which means you need to generate it yourself. With an existing `shard.lock` file, `crystal2nix` can be run. ```bash $ git clone https://github.com/mint-lang/mint $ cd mint $ git checkout 0.5.0 +$ if [ ! -f shard.lock ]; then nix-shell -p shards --run "shards lock"; fi $ nix-shell -p crystal2nix --run crystal2nix ``` |
