 Database logging is disabled by default. You can enable it in ```config.json``` by setting ```logToDatabase``` to true.
 This requires sqlite3 drivers to be installed.
 
+#### What's being changed?
+For the changelog, check out the [CHANGELOG](CHANGELOG.md) file.

 #### How do I get added?
 At the moment, the main "minetrack.me" site is only accepting networks that average roughly 1,000 players at peak for **PC** servers, and 100 players at peak for **PE** servers. This is due to limited capacity and it's functionality. If you fit this description, you're welcome to open a Pull Request adding the network to ```config.json```.
