+The Drop Desktop Client is the companion app for [Drop](https://github.com/Drop-OSS/drop). It is the official & intended way to download and play games on your Drop server.
+
+## Internals
+
+It uses a Tauri base with Nuxt 3 + TailwindCSS on top of it, so we can re-use components from the web UI.
 
 ## Development
+Before setting up a development environemnt, be sure that you have a server set up. The instructions for this can be found on the [Drop Docs](https://docs.droposs.org/docs/guides/quickstart).
 
-Install dependencies with `yarn`
+Then, install dependencies with `yarn`. This'll install the custom builder's dependencies. Then, check everything works properly with `yarn tauri build`. 
 
-Run the app in development with `yarn tauri dev`. NVIDIA users on Linux, use shell script `./nvidia-prop-dev.sh`
+Run the app in development with `yarn tauri dev`. NVIDIA users on Linux, use shell script `./nvidia-prop-dev.sh`
 
 To manually specify the logging level, add the environment variable `RUST_LOG=[debug, info, warn, error]` to `yarn tauri dev`:
 
-e.g. `RUST_LOG=debug yarn taudi dev`

+
+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.
