+# Git: extract-version-from-tag
+
+## Behavior
+
+Extract version number from semver tag. 
+WARNING: Must be run on tag reference.
+
+## Usage
+
+```yaml
+jobs:
+  extract-version:
+    runs-on: ubuntu-latest
+    steps:
+      - name: "Checkout Code"
+        uses: "actions/checkout@v3"
+
+      - name: "extract version"
+        uses: "meero-com/github-actions-shared-workflows/actions/git/extract-version-from-tag@main"
+        with:
+          PREFIX: "DEV-v"
+```
+
+Will outputs
+
+```yaml
+version_number: 1.2.3 # if ran on tag DEV-v1.2.3
+```
+
+Beware of using a `@ref` (`@main` in the example above) which suits your stability requirements in your workflow:
+
+* Use `@main` if you always want to use the latest version of the workflow.
+* Use `@<tag>` if you wan to use a specific frozen version of the workflow.
