 Drop app is the companion app for [Drop](https://github.com/Drop-OSS/drop). It uses a Tauri base with Nuxt 3 + TailwindCSS on top of it, so we can re-use components from the web UI.
 
+## Running

+- Signin (with custom server)
+- Database registering & recovery
+- Dynamic library fetching from server
+- Installing & uninstalling games
+- Download progress monitoring
+- Launching / playing games

+
+Welcome to the download manager, the most overengineered, glorious piece of bullshit.
+
+The download manager takes a queue of ids and their associated
+DownloadAgents, and then, one-by-one, executes them. It provides an interface
+to interact with the currently downloading agent, and manage the queue.
+
+When the DownloadManager is initialised, it is designed to provide a reference
+which can be used to provide some instructions (the DownloadManagerInterface),
+but other than that, it runs without any sort of interruptions.
+
+It does this by opening up two data structures. Primarily is the command_receiver,
+and mpsc (multi-channel-single-producer) which allows commands to be sent from
+the Interface, and queued up for the Manager to process.
+
+These have been mapped in the DownloadManagerSignal docs.
+
+The other way to interact with the DownloadManager is via the donwload_queue,
+which is just a collection of ids which may be rearranged to suit
+whichever download queue order is required.
+
++----------------------------------------------------------------------------+
+| DO NOT ATTEMPT TO ADD OR REMOVE FROM THE QUEUE WITHOUT USING SIGNALS!!     |
+| THIS WILL CAUSE A DESYNC BETWEEN THE DOWNLOAD AGENT REGISTRY AND THE QUEUE |
+| WHICH HAS NOT BEEN ACCOUNTED FOR                                           |
++----------------------------------------------------------------------------+
+
+This download queue does not actually own any of the DownloadAgents. It is
+simply an id-based reference system. The actual Agents are stored in the
+download_agent_registry HashMap, as ordering is no issue here. This is why
+appending or removing from the download_queue must be done via signals.

-Welcome to the download manager, the most overengineered, glorious piece of bullshit.
-
-The download manager takes a queue of game_ids and their associated
-GameDownloadAgents, and then, one-by-one, executes them. It provides an interface
-to interact with the currently downloading agent, and manage the queue.
-
-When the DownloadManager is initialised, it is designed to provide a reference
-which can be used to provide some instructions (the DownloadManagerInterface),
-but other than that, it runs without any sort of interruptions.
-
-It does this by opening up two data structures. Primarily is the command_receiver,
-and mpsc (multi-channel-single-producer) which allows commands to be sent from
-the Interface, and queued up for the Manager to process.
-
-These have been mapped in the DownloadManagerSignal docs.
-
-The other way to interact with the DownloadManager is via the donwload_queue,
-which is just a collection of ids which may be rearranged to suit
-whichever download queue order is required.
-
-+----------------------------------------------------------------------------+
-| DO NOT ATTEMPT TO ADD OR REMOVE FROM THE QUEUE WITHOUT USING SIGNALS!!     |
-| THIS WILL CAUSE A DESYNC BETWEEN THE DOWNLOAD AGENT REGISTRY AND THE QUEUE |
-| WHICH HAS NOT BEEN ACCOUNTED FOR                                           |
-+----------------------------------------------------------------------------+
-
-This download queue does not actually own any of the GameDownloadAgents. It is
-simply a id-based reference system. The actual Agents are stored in the
-download_agent_registry HashMap, as ordering is no issue here. This is why
-appending or removing from the download_queue must be done via signals.
