You can use it as a Github Action like this:

.github/main.workflow

workflow "Main" {
  on = "push"
  resolves = ["Psalm"]
}

action "Psalm" {
  uses = "docker://mickaelandrieu/psalm-ga"
  secrets = ["GITHUB_TOKEN"]
}

to add specific arguments:

workflow "Main" {
  on = "push"
  resolves = ["Psalm"]
}

action "Psalm" {
  uses = "docker://mickaelandrieu/psalm-ga"
  secrets = ["GITHUB_TOKEN"]
+  args = "--find-dead-code --threads=8 --diff --diff-methods"
}

You can copy/paste the .github folder (under examples/) to your project and thats all!
