+
+### Installation
+
+Since ITD 0.0.7, packages are built and uploaded whenever a new release is created.
+
+#### Arch Linux
+
+Use the `itd-bin` or `itd-git` AUR packages.
+
+#### Debian/Ubuntu
+
+- Go to the [latest release](https://gitea.arsenm.dev/Arsen6331/itd/releases/latest) and download the `.deb` package for your CPU architecture. You can find your architecture by running `uname -m` in the terminal.
+- Run `sudo apt install <package>`, replacing `<package>` with the path to the downloaded file. Note: relative paths must begin with `./`.
+- Example: `sudo apt install ~/Downloads/itd-0.0.7-linux-aarch64.deb`
+
+#### Fedora
+
+- Go to the [latest release](https://gitea.arsenm.dev/Arsen6331/itd/releases/latest) and download the `.rpm` package for your CPU architecture. You can find your architecture by running `uname -m` in the terminal.
+- Run `sudo dnf install <package>`, replacing `<package>` with the path to the downloaded file.
+- Example: `sudo dnf install ~/Downloads/itd-0.0.7-linux-aarch64.rpm`
+
+#### Alpine (and postmarketOS)
+
+- Go to the [latest release](https://gitea.arsenm.dev/Arsen6331/itd/releases/latest) and download the `.apk` package for your CPU architecture. You can find your architecture by running `uname -m` in the terminal.
+- Run `sudo apk add --allow-untrusted <package>`, replacing `<package>` with the path to the downloaded file.
+- Example: `sudo apk add --allow-untrusted ~/Downloads/itd-0.0.7-linux-aarch64.apk`
+
+Note: `--allow-untrusted` is required because ITD isn't part of a repository, and therefore is not signed.

 This daemon creates a UNIX socket at `/tmp/itd/socket`. It allows you to directly control the daemon and, by extension, the connected watch.
 
-The socket accepts JSON requests. For example, sending a notification looks like this:
+The socket uses my [lrpc](https://gitea.arsenm.dev/Arsen6331/lrpc) library for requests. This library accepts requests in msgpack, with the following format:
 
 ```json
-{"type": "notify", "data": {"title": "title1", "body": "body1"}}
+{"Receiver": "ITD", "Method": "Notify", "Arg": {"title": "title1", "body": "body1"}, "ID": "some-id-here"}
 ```
 
-It will return a JSON response. A response can have 3 fields: `error`, `msg`, and `value`. Error is a boolean that signals whether an error was returned. If error is true, the msg field will contain the error. Value can contain any data and depends on what the request was.
+It will return a msgpack response, the format of which can be found [here](https://gitea.arsenm.dev/Arsen6331/lrpc/src/branch/master/internal/types/types.go#L30). The response will have the same ID as was sent in the request in order to allow the client to keep track of which request the response belongs to.
 
-The various request types and their data requirements can be seen in `internal/types`. I can make separate docs for it if I get enough requests.
+---
+
+### Transliteration
+
+Since the PineTime does not have enough space to store all unicode glyphs, it only stores the ASCII space and Cyrillic. Therefore, this daemon can transliterate unsupported characters into supported ones. Since some languages have different transliterations, the transliterators to be used must be specified in the config. Here are the available transliterators:
+
+- eASCII
+- Scandinavian
+- German
+- Hebrew
+- Greek
+- Russian
+- Ukranian
+- Arabic
+- Farsi
+- Polish
+- Lithuanian
+- Estonian
+- Icelandic
+- Czech
+- French
+- Armenian
+- Korean
+- Chinese
+- Romanian
+- Emoji
+
+Place the desired map names in an array as `notifs.translit.use`. They will be evaluated in order. You can also put custom transliterations in `notifs.translit.custom`. These take priority over any other maps. The `notifs.translit` config section should look like this:
+
+```toml
+[notifs.translit]
+    use = ["eASCII", "Russian", "Emoji"]
+    custom = [
+        "test", "replaced"
+    ]

-#### Interactive mode
+---
 
-Running `itctl` by itself will open interactive mode. It's essentially a shell where you can enter commands. For example:
+### `itgui`
 
+In `cmd/itgui`, there is a gui frontend to the socket of `itd`. It uses the [Fyne library](https://fyne.io/) for Go.
+
+#### Compilation
+
+Before compiling, certain prerequisites must be installed. These are listed on the following page: https://developer.fyne.io/started/#prerequisites
+
+It can be compiled by running:
+
+```shell
+go build ./cmd/itgui
 ```
-$ itctl                        
-itctl> fw ver
-1.3.0
-itctl> get batt
-81%
-itctl> get heart
-92 BPM
-itctl> set time 2021-08-22T00:06:18-07:00
-itctl> set time now
-itctl> exit
-```
+
+#### Cross-compilation
+
+Due to the use of OpenGL, cross-compilation of `itgui` isn't as simple as that of `itd` and `itctl`. The following guide from the Fyne website should work for `itgui`: https://developer.fyne.io/started/cross-compiling.
