 * Create a directory where cargohold will store the uploaded files
 * Set the directory's owner to the user you want uwsgi to run the application under
 * Edit `backend/config.py` to match your setup
 * Edit `configs/nginx.config` to match your setup
 	* Note that the `client_max_body_size` directive will limit the maximum size of a single uploaded file
-* Install `configs/nginx.config` to `/etc/nginx/sites-enabled`
+* Install `configs/nginx.config` to `/etc/nginx/sites-enabled/`
 * Edit `configs/uwsgi.ini` to match your setup

+The database stores the the following data for each alias
+
+* *Alias*: The identifier to be appended to the base URL
+* *User*: The user the identifier belongs to, for administrative and storage accounting purposes
+* *Real path*: The on-disk directory name where, when prepended with both the `fileroot` and optionally, the `userdir`, the data is stored. Multiple aliases may point to the same real path.
+* *Access level*: The access level this alias permits to the real path. A string consisting of any of the characters *c* (*C*reate / Upload), *r* (*R*etrieve / Read), *u* (*U*pdate), *d* (*D*elete) in any order.
+* *Storage limit*: Per-alias storage limit (applied when uploading)
+* *Display mode*: Parameter 
+
+The storage limit for each alias (applied when uploading files) is calculated as the minimum of the following parameters
+
+* Global disk size limit
+* `global_limit` in `backend/config.py`
+* The per-user limit
+* The per-alias limit
