+### 3. Exporting Shareable Images (`.png`)
+
+In addition to viewing the dashboards in a browser, the project includes a powerful script to programmatically save the 'image views' as static `.png` files. This is ideal for automation, scheduled tasks (cron jobs), or sharing the results on social media platforms like your `r/rstat` subreddit.
+
+#### One-Time Setup
+
+The image exporter uses the Playwright library to control a headless browser. Before using it for the first time, you must install the necessary browser runtimes with this command:
+
+```bash
+playwright install
+```
+
+#### Usage Workflow
+
+The exporter works by taking a high-quality screenshot of the live web page. Therefore, the process requires two steps running in two separate terminals.
+
+**Step 1: Start the Web Dashboard**
+
+The web server must be running for the exporter to have a page to screenshot. Open a terminal and run:
+
+```bash
+rstat-dashboard
+```
+Leave this terminal running.
+
+**Step 2: Run the Export Script**
+
+Open a **second terminal** in the same project directory. You can now run the `export_image.py` script with the desired arguments.
+
+**Examples:**
+
+*   To export the **daily** summary image for `r/wallstreetbets`:
+    ```bash
+    python export_image.py wallstreetbets
+    ```
+
+*   To export the **weekly** summary image for `r/wallstreetbets`:
+    ```bash
+    python export_image.py wallstreetbets --weekly
+    ```
+
+*   To export the **overall** summary image (across all subreddits):
+    ```bash
+    python export_image.py --overall
+    ```
+
+#### Output
+
+After running a command, a new `.png` file (e.g., `wallstreetbets_daily_1690000000.png`) will be saved in the images-directory in the root directory of the project.
+
+
+
+## 4. Full Automation: Posting to Reddit via Cron Job
+
+The final piece of the project is a script that automates the entire process: scraping data, generating an image, and posting it to a target subreddit like `r/rstat`. This is designed to be run via a scheduled task or cron job.
+
+### Prerequisites for Posting
+
+The posting script needs to log in to your Reddit account. You must add your Reddit username and password to your `.env` file.
+
+**Add these two lines to your `.env` file:**
+```
+REDDIT_USERNAME=YourRedditUsername
+REDDIT_PASSWORD=YourRedditPassword
+```
+*(For security, it's recommended to use a dedicated bot account for this, not your personal account.)*
+
+### The `post_to_reddit.py` Script
+
+This is a standalone script located in the project's root directory that finds the most recently generated image and posts it to Reddit.
+
+**Manual Usage:**
+
+You can run this script manually from your terminal. This is great for testing or one-off posts.
+
+*   **Post the latest OVERALL summary image to `r/rstat`:**
+    ```bash
+    python post_to_reddit.py
+    ```
+
+*   **Post the latest DAILY image for a specific subreddit:**
+    ```bash
+    python post_to_reddit.py --subreddit wallstreetbets
+    ```
+
+*   **Post the latest WEEKLY image for a specific subreddit:**
+    ```bash
+    python post_to_reddit.py --subreddit wallstreetbets --weekly
+    ```
+
+*   **Post to a different target subreddit (e.g., a test subreddit):**
+    ```bash
+    python post_to_reddit.py --target-subreddit MyTestSub
+    ```
+
+### Setting Up the Cron Job for Full Automation
+
+To run the entire pipeline automatically every day, you can use a simple shell script controlled by `cron`.
+
+**Step 1: Create a Job Script**
+
+Create a file named `run_daily_job.sh` in the root of your project directory. This script will run all the necessary commands in the correct order.
+
+**`run_daily_job.sh`:**
+```bash
+#!/bin/bash
+
+# CRITICAL: Navigate to the project directory using an absolute path.
+# Replace '/path/to/your/project/reddit_stock_analyzer' with your actual path.
+cd /path/to/your/project/reddit_stock_analyzer
+
+# CRITICAL: Activate the virtual environment using an absolute path.
+source /path/to/your/project/reddit_stock_analyzer/.venv/bin/activate
+
+echo "--- Starting RSTAT Daily Job on $(date) ---"
+
+# 1. Scrape data from the last 24 hours for all subreddits in the config.
+echo "Step 1: Scraping new data..."
+rstat --config subreddits.json --days 1
+
+# 2. Start the dashboard in the background so the exporter can access it.
+echo "Step 2: Starting dashboard in background..."
+rstat-dashboard &
+DASHBOARD_PID=$!
+
+# Give the server a moment to start up.
+sleep 10
+
+# 3. Export the overall summary image.
+echo "Step 3: Exporting overall summary image..."
+python export_image.py --overall
+
+# 4. Post the newly created overall summary image to r/rstat.
+echo "Step 4: Posting image to Reddit..."
+python post_to_reddit.py --target-subreddit rstat
+
+# 5. Clean up by stopping the background dashboard server.
+echo "Step 5: Stopping dashboard server..."
+kill $DASHBOARD_PID
+
+echo "--- RSTAT Daily Job Complete ---"
+```**Before proceeding, you must edit the two absolute paths at the top of this script to match your system.**
+
+**Step 2: Make the Script Executable**
+
+In your terminal, run the following command:
+```bash
+chmod +x run_daily_job.sh
+```
+
+**Step 3: Schedule the Cron Job**
+
+1.  Open your crontab editor by running `crontab -e`.
+2.  Add a new line to the file to schedule the job. For example, to run the script **every day at 10:00 PM**, add the following line:
+
+    ```
+    0 22 * * * /path/to/your/project/reddit_stock_analyzer/run_daily_job.sh >> /path/to/your/project/reddit_stock_analyzer/cron.log 2>&1
+    ```
+    *   `0 22 * * *` means at minute 0 of hour 22, every day, every month, every day of the week.
+    *   `>> /path/to/your/.../cron.log 2>&1` is highly recommended. It redirects all output (both standard and error) from the script into a log file, so you can check if the job ran successfully.
+
+Your project is now fully automated to scrape, analyze, visualize, and post data every day.
