+
+## Instruction 📖
+
+### 1. Add to your `README.md` file two lines that indicate where to put the commit picture:
+
+    <!-- LATESTCOMMIT:START -->
+    <!-- LATESTCOMMIT:END -->
+    > (Anything between those two lines will be deleted and replaced with the commit picture)
+
+### 2. Create a workflow file
+
+In your repository create the following file:
+`.github/workflows/last-commit.yml`
+
+```yaml
+name: Latest commit message made by user
+on:
+schedule:
+# Runs every hour
+- cron: '0 * * * *'
+
+workflow_dispatch:
+
+jobs:
+
+update-readme-with-last-commit:
+
+name: Update this repo's README with latest commit made
+
+runs-on: ubuntu-latest
+
+steps:
+
+- uses: actions/checkout@v2
+
+- uses: estarossa0/readme-last-commit@master
+```
+
+The action above runs every hours, you can change it as you like by changing `- cron` using [cron syntax](https://jasonet.co/posts/scheduled-actions/#the-cron-syntax).
+
+> 💡 The action only check for your public commits, no private commits will be displayed.
