- * perchdir=[resume/new/ask/#]: When Slax is started from a writable media,
-   all changes are saved to subdirectories of /slax/changes/ to make them
-   persistent. This parameter allows you to choose what session to resume.
-   Use perchdir=resume to auto resume the session used on previous boot.
+ * perchdir=[resume|new|ask|device]: All changes you make to Slax can be

  * perchsize=[size_MB]: When stored on non-linux filesystem such as FAT32,
    sessions are limited to maximum size of 16GB. You can increase the limit
-   with this parameter, use for example perchsize=32000 for 32GB.
+   with this parameter, use just once. For example perchsize=32GB
 
- * from=[file/path/device] is used to set a directory or even device from
-   which is Slax started. For example, from=/slax, from=/dev/sr1/slaxdata

  * noload=[regex] is used to specify what modules will not be loaded. Use
