-### Example
-
-An example config can be found by running:
-
-```sh
-navi info config-example
-```
-
-You can also read it online by clicking [here](./config_file_example.yaml).
-
-### Location
-
-Run the following command to check where the config file is/should be located:
+## Config file path
 
+The default config file path is set by the `$NAVI_CONFIG`environment variable. If it is not set, it fallbacks to `~/.config/navi/config.yaml`. The command
 ```sh
 navi info config-path
 ```
-
-### Creating the file
-
-Run the following command to generate a config file with the default parameters:
+prints which config file path is being used. You can get an config file example by running
+```sh
+navi info config-example
+```
+or by clicking [here](./config_file_example.yaml). To this this example your config file, run
 
 ```sh
 navi info config-example > "$(navi info config-path)"
 ```
+## Cheat sheet paths
+
+The default `.cheat` files paths are defined in the `$NAVI_PATH` environment variable in a colon-separated list, e.g.,
+```
+export NAVI_PATH='/path/to/a/dir:/path/to/another/dir:/yet/another/dir'
+```
+If this environment variable is unset or if all directories do not exist, `navi` uses that paths defined in its config files. Finally, if there is no config file or if there is no `.cheat` file paths settings there, the default `.cheat` file path fallbacks to `~/.local/share/navi/cheats/`. The command
+```sh
+navi info cheats-path
+```
+prints to you all paths used to search for `.cheat` files. 
+
+You can also add other paths at runtime by running `navi` with the `--path` option and a colon-separed paths list, e.g.,
+```sh
+navi --path '/some/dir:/other/dir'
+```
+It's irrelevant the directory structure within each path. They can even be all in a single file if you wish, as long as you split them accordingly with lines starting with `%`.
