-- `^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 `< 2.0.0`.

 - `nightly` will install the latest nightly build.
+- `1.7-nightly` will install the latest nightly build for the upcoming 1.7 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).
 
+#### Prereleases
+
+There are two methods of including pre-releases in version matching:
+
+1. Including the pre-release tag in the version itself, e.g. `^1.3.0-rc1`.
+2. Setting the input `include-all-prereleases` to `true`.
+
+These behave slightly differently.
+
+1. If the version `a.b.c` contains pre-release tag, all pre-releases of version `a.b.c` will be included in the version matching.
+For example, `^1.3.0-rc1` would match `1.3.0-rc2` but would **not** match `1.4.0-rc1` once released.
+2. If `include-preleases` is set to true, **all** pre-releases of all versions will be included in the version matching. In this case, `^1.3.0-rc1` would match `1.4.0-rc1` once released.
+
+**Example:** Without `include-all-prereleases: true`, the version `^1.3.0-rc1` would match `1.3.0-rc1`, `1.3.0-rc2`, `1.3.0`, `1.4.0` once they are released.
+With `include-all-prereleases: true`, it would match `1.3.0-rc1`, `1.3.0-rc2`, `1.3.0`, `1.4.0-rc1`, `1.4.0`.
+
+If you want to run tests against the latest tagged version, no matter what version that is, you can use
+
+```yaml
+- uses: julia-actions/setup-julia@v1
+  with:
+    version: '1'
+    include-all-prereleases: true
+```
+
+#### Recently released versions
+
 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.

 ### versioninfo
 
-By default, only a brief version identifier is printed in the run log. You can display the full `versioninfo` by adding `show-versioninfo`.
-Here's an example that prints this information just for `nightly`:
+By default, only the output of `julia --version` is printed as verification that Julia has been installed for stable versions of Julia.
+`InteractiveUtils.versioninfo()` is run by default for nightly builds.
 
-```yaml
-    - uses: julia-actions/setup-julia@v1
-      with:
-        version: ${{ matrix.version }}
-        arch: ${{ matrix.arch }}
-        show-versioninfo: ${{ matrix.version == 'nightly' }}
- ```
- 
-You use `'true'` if you want it printed for all Julia versions.
+Starting Julia and printing the full versioninfo takes a significant amount of time (1s or ~10% of the total build time in testing), so you may not want to run it in every build, in particular on paid runners as this cost will add up quickly.
+However, `julia --version` does not provide sufficient information to know which commit a nightly binary was built from, therefore it is useful to show the full versioninfo on nightly builds regardless.
+
+You can override this behaviour by changing the input to `never` if you never want to run `InteractiveUtils.versioninfo()` or to `true` if you always want to run `InteractiveUtils.versioninfo()`, even on stable Julia builds.
