 ### Config
 
-You can configure the repositories to use in the `config.json` file,
-located in `fdroidcl`'s config directory. This will be
-`~/.config/fdroidcl/config.json` on Linux.

-You can run `fdroidcl defaults` to create the config with the default

-### Missing features
+You can configure what repositories to use in the `config.json` file. On Linux,

- * Handle multiple Android devices
- * No need to install a client on the device
