+Architecture
+------------
+
+![Architecture diagram][1]
+
+
+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
