-StackEdit uses [RequireJS][2] for asynchronous module definition ([AMD][3]). 
-
-### core
-
-The `core` module is responsible for:
-
-- creating the layout (using [UI Layout][4])
-- creating the editor (using [PageDown][5])
-- Loading/saving the settings
-- detecting the offline status
-
-### fileMgr
-
-The `fileMgr` module is responsible for:
-
-- creating/deleting local files
-- switching from one file to another
-- setting/removing file's sync/publish location
-
-### synchronizer
-
-The `synchronizer` module is responsible for:
-
-- creating a new local file from a sync location (import)
-- creating a new sync location from a local file (export)
-- running 2 ways synchronization (upload and download) for all sync locations
-
-### publisher
-
-The `publisher` module is responsible for:
-
-- creating new publish locations
-- updating existing publish locations
-
-#### publisher's providers
-
-A `provider` module can be associated with the `publisher` module if it implements the following functions:
-
-- `newPublishAttributes()`: returns a new [`publishAttributes`][6] object in order to create a new publish location
-- `publish()`: performs publishing of one publish location
-
-#### publishAttributes
-
-A `publishAttributes` object is an object that describes a publish location. Attributes list differs from one provider to another except for the following attributes:
-
-- `publishIndex`: the unique index of the publish location
-- `provider`: the `provider` module that handles the publish location
-- `format`: the publishing format for the publish location. It can be:
-	- `markdown` for Markdown format
-	- `html` for HTML format
-	- `template` for template format
