 See [action.yml](action.yml).
 
-Take a look at [github.com/exercism/julia](https://github.com/exercism/julia/pull/153) for an example, non-package Julia project making use of this action.
+You can find a list of example workflows making use of this action here: [julia-actions/example-workflows](https://github.com/julia-actions/example-workflows).
 
-### Basic:
+### Basic
 
 ```yaml
 steps:
 - uses: actions/checkout@v1.0.0
-- uses: julia-actions/setup-julia@v0.1.0
+- uses: julia-actions/setup-julia@v1
   with:
     version: 1.0.4
 - run: julia -e 'println("Hello, World!")'
 ```
 
-### Matrix Testing:
+### Julia Versions
+
+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.
+
+**Warning:** It is strongly recommended to wrap versions 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` is parsed as `1`.
+
+#### Examples
+
+- `1.2.0` is a valid semver version. The action will try to download exactly this version. If it's not available, the build step will fail.
+- `1.0` is a version range that will match the highest available Julia version that starts with `1.0`, e.g. `1.0.5`.
+- `^1.3.0-rc1` is a caret version range that includes pre-releases starting at `rc1`. It matches all versions `≥ 1.3.0-rc1` and `< 1.4.0`.
+- `^1.3-0` is a caret 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.
+
+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).
+
+#### WARNING: Version ranges are experimental and potentially out of date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.
+
+### Matrix Testing
+
+`bash` is chosen as shell to enforce consistent behaviour across operating systems. [Other shells](https://help.github.com/en/actions/reference/workflow-syntax-for-github-actions#using-a-specific-shell) are available but you may have to escape quotation marks or otherwise adjust the syntax.

-### `setup-julia`:
-* Check if a cached version of Julia is available instead of installing it everytime CI runs.
-* Add version shortcuts like `1.x`, `1.1.x`, `latest` and `lts`.
-* Add support for nightly Julia builds.
-* Support 32-bit Julia on 64-bit windows.
-* Write some unit tests for the action.
-* Figure out the best way to handle versioning.
-* Hash and signature checks.
+Alternatively, you can include specific version and OS combinations that will use 32-bit Julia:
 
-### Other Julia-related actions:
+```yaml
+jobs:
+  test:
+    runs-on: ${{ matrix.os }}
+    strategy:
+      matrix:
+        julia-version: ['1.0', '1.2.0', '^1.3.0-rc1']

+          - os: windows-latest
+            julia-version: ['1.0.4']
+            julia-arch: x86

+          version: ${{ matrix.julia-version }}
+      - run: julia -e 'println("Hello, World!")'
+        shell: bash
+```
 
-These would be nice to have but I make no promises of ever creating them myself.
+## Versioning
 
-* Default build script for packages, similar to how Travis CI works if you don't specify a script.
-* Find out if it's possible to cache packages using [`@actions/tool-cache`](https://github.com/actions/toolkit/tree/master/packages/tool-cache).
-* Actions for standard tools like Documenter, Coverage reporting and so on
-* Actions for registering and tagging package releases instead of relying on external apps.
+This action follows [GitHub's advice](https://help.github.com/en/articles/about-actions#versioning-your-action) on versioning actions, with an additional `latest` tag.
 
-## Words of caution
+If you don't want to deal with updating the version of the action, similiarly to how Travis CI handles it, use `latest` or major version branches. [Dependabot](https://dependabot.com/) can also be used to automatically create Pull Requests to update actions used in your workflows.
 
-This action will likely be updated quite frequently in the near future. I'm sharing it now so that others who want to try out Julia on GitHub actions can do so without relying on Docker.
+It's unlikely, but not impossible, that there will be breaking changes post-v1.0.0 unless a new major version of Julia is introduced.
 
-**DO NOT USE THIS AS YOUR ONLY FORM OF CI** (yet).
+You can specify commits, branches or tags in your workflows as follows:
 
-Unfortunately, because non-container actions must use JavaScript/TypeScript as scripting language, `npm` is involved. The dependencies are vendored but this action relies 100% on GitHub to audit the dependencies they add to their action toolkit.
+```yaml
+steps:
+  - uses: julia-actions/setup-julia@6ae948d # commit SHA
+  - uses: julia-actions/setup-julia@master  # branch
+  - uses: julia-actions/setup-julia@latest  # latest version tag (may break existing workflows)
+  - uses: julia-actions/setup-julia@v1      # major version tag
+  - uses: julia-actions/setup-julia@v0.1.0  # specific version tag
+```

+## Privacy Info
+
+Julia version 1.5 and later collects telemetry information during certain `Pkg` operations.
+Please refer to <https://julialang.org/legal/data/> for information on what data is collected.
+This action does not alter the Julia installation in any way, therefore telemetry on your CI runs will be collected by the Julia Pkg server unless you opt out.
+In a later release of the action, an action input to opt out of telemetry will be provided but for now you need to add a step to your workflows that edits `telemetry.toml` in the CI environment as described in the [Opting Out](https://julialang.org/legal/data/#opting_out) section of the above document.
+
+**This action itself does not collect any kind of personal data or telemetry information.**
