 ### Without map persistence

-```
-docker run -d \
-  -v [PATH]:/opt/factorio/saves \
-  -p [PORT]:34197/udp \

 This will generate a new random map with default settings and save it onto the volume.
 Replace [PATH] with a path to a folder on the host where the map will be saved.

 ### With existing map
 
+It's the same as above, it takes the last modified file which contains the word save in the filename as current save when booting the server. This allows when upgrading the container to take the last save, you don't have to rename the last autosave as save.zip

 ### Autosave interval
 
 You can set the autosave interval. By default it is set at 2 minutes bud you can change it by launching the container with the `FACTORIO_AUTOSAVE_INTERVAL` variable to whatever suits you best.
+
 ```
 docker run -d \
   --env FACTORIO_AUTOSAVE_INTERVAL=[NUMBER] \
   -p [PORT]:34197/udp  \
   dtandersen/factorio
 ```
+
 Where [NUMBER] is the number of minutes between autosaves. 
 
 ### Autosave slots
 
 You can set the number of autosave slots. By default it is set at 3 slots bud you can change it by launching the container with the `FACTORIO_AUTOSAVE_SLOTS` variable to whatever suits you best.
+
 ```
 docker run -d \
   --env FACTORIO_AUTOSAVE_SLOTS=[NUMBER] \
   -p [PORT]:34197/udp  \
   dtandersen/factorio
 ```
+
 Where [NUMBER] is the number of autosave slots.  
 
 ### Mounting mod volume
 
 As everybody knows about factorio is you can add mods to it. Now you can also do it in this docker image by mounting a volume.
+
 ```
 docker run -d \
   -v [PATH]:/opt/factorio/mods \
   -p [PORT]:34197/udp \
   dtandersen/factorio
 ```
+
 Where [PATH] is the path to the folder with your mods.
 
 ### Allowing in-game commands
 
 I've always disabled in-game commands because I think it is like cheating, however, you can enable them by setting the the `FACTORIO_DISSALOW_COMMANDS` variable to "false".
