+# Budget
+Budget helps you control your Mastodon's server bills and donations and share current financial status with your users by posting them via this Budget bot.
+
+### Dependencies
+
+-   **Python 3**
+-   Postgresql server
+-   Mastodon's bot account
+
+### Usage:
+
+Within Python Virtual Environment:
+
+1. Run `pip install -r requirements.txt` to install needed Python libraries.
+
+2. Run `python db-setup.py` to setup and create new Postgresql database and needed tables in it.  
+
+3. Run `python setup.py` to get your Mastodon's bot account tokens and to be able to post your server's financial status.
+
+4. Run `python addincome.py` to add your donations.  
+
+5. Run `python addbill.py` to add your server or domain bills.  
+
+6. Use your favourite scheduling method to set `python budget.py` to run regularly. It will post your finances to your fediverse server.
