+
+Remember that a discord message may be transformed to multiple matrix messages.
+
+A database will be used to store the discord id to matrix event id mapping. Table columns:
+- discord id
+- matrix id
+- the "type" of the matrix id, used to update things properly next time. for example, whether it is the message text or an attachment
+
+There needs to be a way to easily manually trigger something later. For example, it should be easy to manually retry sending a message, or check all members for changes, etc.
+
+## Transforming content
+
+1. Upload attachments to mxc if they are small enough.
+2. Convert discord message text and embeds to matrix event.
+	1. Convert discord mentions, names, channel links, message links, and emojis to intermediate formats.

+5. Send attachments.
+6. Store in database.
+

+
+(but I should be able to manually call this function at any time to run the same code on any given channel)
+
+1. Compare current channel against cached version in database.
+2. If channel does not yet exist in database:
