+# To push back to a repo in a github action
+
+I wanted to have a GitHub Action step push back to the repo it is running in. 
+
+For that you need the `write`  permission. which can be added like so:
+
+```yaml
+permissions:
+  contents: write
+```
+
+from: [git - Push to origin from GitHub action - Stack Overflow](https://stackoverflow.com/a/58393457)
+
+eg in: [add write permission · jamesmstone/chess@d0a3250 · GitHub](https://github.com/jamesmstone/chess/commit/d0a3250e8cdafa56fa549a7d5513cd0b170a83c8)
+
+
+```yaml
+name: Push commit
+on: push
+permissions:
+  contents: write
+jobs:
+  report:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v3
+      - name: Create report file
+        run: date +%s > report.txt
+      - name: Commit report
+        run: |
+          git config --global user.name 'Your Name'
+          git config --global user.email '[email protected]'
+          git commit -am "Automated report"
+          git push
+```
