+# Reddit Mastodon Crossposter
+
+## Usage
+
+1. Install conda env with `conda env create -f environment.yml`.
+
+2. Initialize PRAW with e.g. `reddit.py` (please refer to the [PRAW docs](https://praw.readthedocs.io)).
+
+3. Initialize Mastodon.py with e.g. `masto.py` (please refer to the [Mastodon.py docs](https://mastodonpy.readthedocs.io)).
+
+4. Set all `.env` variables if there are any remaining.
+
+5. Create an `post_toots.sh` and make it executable:
+
+    ```sh
+    #!/bin/bash
+
+    conda activate reddit
+    python "/absolute/path/to/script.py"
+    conda deactivate
+    ```
+
+6. Open the a (user) cronjob editor with `crontab -e` and add the line `0 * * * * /absolute/path/to/post_toots.sh > /dev/null 2>&1`. This cronjob runs hourly and the command outputs are not mailed to the user. Alternatively, `2>&1` can be ommited for debugging purposes if the error outputs should be mailed to the user.
