 Description   

This is very obscure. Please reword to make it readable and understandable:

Changed in version 3.2: With WiredTiger, MongoDB utilizes both the filesystem cache and WiredTiger cache. By default, starting in MongoDB 3.2, the WiredTiger cache will use 60% of RAM minus 1 GB or it will use 1 GB, whichever is larger. For systems with up to 10 GB of RAM, this is less than or equal to the 3.0 setting. For systems with more than 10 GB of RAM, the configuration is greater than the 3.0 setting.
 
In MongoDB 3.0, the WiredTiger cache, by default, uses either 1 GB or half of the installed physical RAM, whichever is larger.
