 - `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.
