 Documentation resources for upcoming [dat](https://github.com/maxogden/dat) 1.0 release and the surrounding ecosystem.
 
+## Hosting
+
+By default, dat looks to host on port 3282, and if taken, will choose a random open port.
+
+## Hidden folder
+
+Dat stores its data in a hidden folder that is stored by default in the user's home directory.
+
+```
+~/.dat
+```
+
+Because of this, data is only ever downloaded once. That is, if you have multiple projects that use the same data (perhaps at different versions) on the same machine, dat will first check the global `.dat` folder.
+
+The global `.dat` folder has inside:
+
+```
+$ ls ~/.dat
+db
+config.json
+```
