## Environment
# This string is used to determine how we should tag the npm release.
# Environment can be one of three choices:
# "development" - this means we tag with the PR number, allowing
# a developer to install this version with `yarn add code-server@<pr-number>`
# "staging" - this means we tag with `beta`, allowing
# a developer to install this version with `yarn add code-server@beta`
# "production" - this means we tag with `latest` (default), allowing
# a developer to install this version with `yarn add code-server@latest`

## Publishing Information
# All the variables below are used to determine how we should publish
# the npm package. We also use this information for bumping the version.
# This is because npm won't publish your package unless it's a new version.
# i.e. for development, we bump the version to <current version>-<pr number>-<commit sha>
# example: "version": "4.0.1-4769-ad7b23cfe6ffd72914e34781ef7721b129a23040"
# We need the current package.json VERSION

# We need TAG to know what to publish under on npm
# Options are "latest", "beta", or "<pr number >"
