-### Inputs
+See [action.yml](action.yml).

-```yaml
- uses: julia-actions/setup-julia@v1
-  with:
-    # The Julia version that will be installed and added as `julia` to the PATH.
-    # See "Julia Versions" below for a list of valid values.
-    #
-    # Warning: It is strongly recommended to wrap this value in quotes.
-    #          Otherwise, the YAML parser used by GitHub Actions parses certain
-    #          versions as numbers which causes the wrong version to be selected.
-    #          For example, `1.0` may be parsed as `1`.
-    #
-    # Default: '1'
-    version: ''
-
-    # The architecture of the Julia binaries.
-    #
-    # Supported values: x64 | x86
-    #
-    # Default: x64
-    arch: ''
-
-    # If true, display the output of InteractiveUtils.versioninfo() after installing.
-    # See "versioninfo" below for example usage.
-    #
-    # Default: false
-    show-versioninfo: ''
-```
-
-### Outputs
-
-```yaml
-outputs:
-  # The installed Julia version.
-  # May vary from the version input if a version range was given as input.
-  #
-  # Example output: '1.5.3'
-
-  julia-version: ''
-  # Path to the directory containing the Julia executable.
-  # Equivalent to JULIA_BINDIR: https://docs.julialang.org/en/v1/manual/environment-variables/#JULIA_BINDIR

 You can either specify specific Julia versions or version ranges. If you specify a version range, the **highest** available Julia version that matches the range will be selected.

 - `^1.3.0-0` is a **caret** version range that includes _all_ pre-releases. It matches all versions `≥ 1.3.0-` and `< 2.0.0`.
 - `~1.3.0-0` is a **tilde** version range that includes _all_ pre-releases. It matches all versions `≥ 1.3.0-` and `< 1.4.0`.
 - `nightly` will install the latest nightly build.
- `1.6-nightly` will install the latest nightly build for the upcoming 1.6 release. This version will only be available during certain phases of the Julia release cycle.

 Internally the action uses node's semver package to resolve version ranges. Its [documentation](https://github.com/npm/node-semver#advanced-range-syntax) contains more details on the version range syntax. You can test what version will be selected for a given input in this JavaScript [REPL](https://repl.it/@SaschaMann/setup-julia-version-logic).

-The available Julia versions are pulled from [`versions.json`](https://julialang-s3.julialang.org/bin/versions.json). This file is automatically updated once a day. Therefore it may take up to 24 hours until a newly released Julia version is available in the action.
+#### WARNING: Version ranges are experimental and potentially out of date
+
+Currently the list of available versions is hardcoded. You have to use the latest version of the action to be able to install the latest Julia versions. Once available we will use a list of versions provided on julialang.org.

-By default, only a brief version identifier is printed in the run log. You can display the full `versioninfo` by adding `show-versioninfo`.
