+# Telepathy for Delta Chat
+
+## What
+
+[Delta Chat](https://delta.chat) is IM over email. [Telepathy](https://telepathy.freedesktop.org)
+is a framework for abstracting over multiple IM protocols. This project glues
+the two together, making the Deltachat 
+
+## Why
+
+Mobile IM, mostly. Desktop IM, also. It's ideal for my pinephone, and lighter
+than the electron desktop client.
+
+## How
+
+This project is written in Rust, just like the main Delta library, so you'll
+need a rust compiler to build it.
+
+It makes use of the `dbus-codegen-rust` crate to convert the
+[telepathy interface specs](https://github.com/TelepathyIM/telepathy-spec) into
+the executable code in `src/telepathy`. This is checked in, but can be
+regenerated like so:
+
+```bash
+$ git submodule init telepathy-spec
+$ git submodule update telepathy-spec
+$ cargo install dbus-codegen-rust
+$ ./scripts/dbus-codegen
+```
+
+`dbus-codegen-rust` doesn't seem to handle namespaced attributes properly, so
+we modify the XML files in `telepathy-spec`... with `sed`. The `tp:type`
+attribute is renamed to `tp:typehint`.
