+# Piped-Alpine
+
+- Patches for backend source code to make it work on Alpine
+- Simple build script and `start.sh`
+- OpenRC configs
+
+Patches may outdate, so open an issue
+if you get an error while script applies them.
+
+## How to build
+1. Install dependencies: `doas apk add git openjdk17 7zip`
+2. Install Rust: `curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh`  
+(Note that you don't need doas or sudo here)
+3. Enter to RustUp environment: `source ~/.cargo/env`
+4. Run the script: `./build.sh`  
+(`bash build.sh` if you executed previous commands from bash)
+
+## How to start Piped
+1. Edit config.properties
+2. Change `/home/piped` in start.sh to directory
+where piped JAR and config are located
+3. Run the script: `./start.sh`
+
+## OpenRC
+1. Change `/home/piped` in piped.init to directory
+where piped JAR and config are located
+2. Change `command_user="piped"` in piped.init to the Piped's user name
+3. Copy this init script: `doas cp piped.init /etc/init.d/piped`
+4. Add it to autostart: `doas rc-update add piped`
+5. Start the service: `doas service piped start`
+
+## I also need to start a proxy, right?
+Yes.
+
+This repo is dedicated only to patches for Piped's backend,
+but I've included an OpenRC config for proxy and this small explanation below.
+
+### Build
+Building proxy is quite easy:
+```bash
+git clone https://github.com/TeamPiped/piped-proxy
+cd piped-proxy
+cargo build --release
+cp target/release/piped-proxy ..
+cd ..
+```
+
+### Start
+Command: `UDS=1 ./piped-proxy`
+
+- With UDS=1, it creates a Unix socket in `./socket/actix.sock`
+instead of listening on TCP port.
+- Without UDS=1, it listens for HTTP connections on :8080 port.
+- If you want to specify other TCP port,
+use `BIND=127.0.0.1:8080` variable (replace port and host with your own),
+and do not enable UDS.
+
+Create `socket` directory before the first start if you have enabled UDS.  
+Also, check if the user from which the proxy is started has write access to the `socket/`.
+
+### OpenRC
+The same as in Piped backend.  
+Copy `proxy.init` replacing the directory and user, replacing `UDS=1` with `BIND=...` if needed.  
+I've set `nginx` as user because otherwise my reverse proxy won't have access to the socket file.
