-### Socket
+### Installation

-This daemon creates a UNIX socket at `/tmp/itd/socket`. It allows you to directly control the daemon and, by extension, the connected watch.
+Since ITD 0.0.7, packages are built and uploaded whenever a new release is created.

-The socket accepts JSON requests. For example, sending a notification looks like this:
+#### Arch Linux

-```json
-{"type": 5, "data": {"title": "title1", "body": "body1"}}
-```
+Use the `itd-bin` or `itd-git` AUR packages.

-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.
+#### Debian/Ubuntu

-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.
+- Go to the [latest release](https://gitea.elara.ws/Elara6331/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

-### Transliteration
+- Go to the [latest release](https://gitea.elara.ws/Elara6331/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`

-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:
+#### Alpine (and postmarketOS)

- eASCII
- Scandinavian
- German
- Hebrew
- Greek
- Russian
- Ukranian
- Arabic
- Farsi
- Polish
- Lithuanian
- Estonian
- Icelandic
- Czech
- French
- Armenian
- Korean
- Chinese
- Romanian
- Emoji
+- Go to the [latest release](https://gitea.elara.ws/Elara6331/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`

-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"
-    ]
-```
+Note: `--allow-untrusted` is required because ITD isn't part of a repository, and therefore is not signed.

 ### `itgui`

-In `cmd/itgui`, there is a gui frontend to the socket of `itd`. It uses the [fyne library](https://fyne.io/) for Go. It can be compiled by running:
+In `cmd/itgui`, there is a gui frontend to the socket of `itd`. It uses the [Fyne library](https://fyne.io/) for Go.
+
+#### Easy Installation
+
+The easiest way to install `itgui` is to use my other project, [LURE](https://gitea.elara.ws/Elara6331/lure). LURE will only work if your package manager is `apt`, `dnf`, `yum`, `zypper`, `pacman`, or `apk`.
+
+Instructions:
+
+1. Install LURE. This can be done with the following command: `curl https://www.elara.ws/lure.sh | bash`.
+2. Check to make sure LURE is properly installed by running `lure ref`.
+3. Run `lure in itgui`. This process may take a while as it will compile `itgui` from source and package it for your distro.
+4. Once the process is complete, you should be able to open and use `itgui` like any other app.
+
+#### 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
 ```

+#### 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.

-#### Interactive mode
+### Socket

-Running `itctl` by itself will open interactive mode. It's essentially a shell where you can enter commands. For example:
+This daemon creates a UNIX socket at `/tmp/itd/socket`. It allows you to directly control the daemon and, by extension, the connected watch.

-```
-$ 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
-```
+The socket uses the [DRPC](https://github.com/storj/drpc) library for requests. The code generated by this framework is located in [`internal/rpc`](internal/rpc)

---
-
-### Installation
-
-To install, install the go compiler and make. Usually, go is provided by a package either named `go` or `golang`, and make is usually provided by `make`. The go compiler must be version 1.16 or newer for the `io/fs` module.
-
-To install, run
-```shell
-make && sudo make install
-```
+The API description is located in the [`internal/rpc/itd.proto`](internal/rpc/itd.proto) file.
