 [configuration](configuration.md).
 
+### Where to store custom data
+
+Freqtrade allows the creation of a user-data directory using `freqtrade create-userdir --userdir someDirectory`.
+This directory will look as follows:
+
+user_data/
+├── backtest_results
+├── data
+├── hyperopts
+├── plot
+└── strategies
+
+You can add the entry "user_data_dir" to your configuration, to always point your bot to this folder.
+Alternatively, pass in `--userdir` to every command.
+
+This directory should contain your custom strategies, custom hyperopts, backtest data (downloaded using either backtesting or the download script) and plot outputs.
+
+It is reccomendet to use version control to keep track of changes to your strategies.
