 Convert RSS feeds into multiple formats
 
-## Features
-
-* [x] Multiple feed sources with flexible TOML config options
-    * [x] Limit channel items
-    * [x] Format time
-    * [x] Multiple export format definition
-* [x] Custom templates
-* [x] Single export or daemon mode with update time
-* [x] Export formats:
-    * [x] HTML
-    * [x] [Gemtext](https://geminiprotocol.net/docs/gemtext.gmi)
-
-## Install
-
-``` bash
-cargo install rssto
-```
-
-## Launch
-
-``` bash
-rssto -c config/example.toml
-```
-> [!TIP]
-> * prepend `RUST_LOG=DEBUG` to print worker details (supported [levels](https://docs.rs/tracing-subscriber/latest/tracing_subscriber/filter/struct.LevelFilter.html))
-> * append `-u TIME` to run as the daemon with `TIME` interval update
-> * see `rssto --help` to print all available options
-
-### Systemd
-
-1. Install `rssto` by copy the binary compiled into the native system apps destination:
-    * Linux: `sudo install /home/user/.cargo/bin/rssto /usr/local/bin/rssto`
-2. Create `systemd` configuration file at `/etc/systemd/system/rssto.service`:
-
-``` rssto.service
-[Unit]
-After=network-online.target
-Wants=network-online.target
-
-[Service]
-Type=simple
-
-User=rssto
-Group=rssto
-
-# Uncomment for debug
-# Environment="RUST_LOG=DEBUG"
-# Environment="NO_COLOR=1"
-
-ExecStart=/usr/local/bin/rssto -c /path/to/config.toml
-
-StandardOutput=file:///home/rssto/debug.log
-StandardError=file:///home/rssto/error.log
-
-[Install]
-WantedBy=multi-user.target
-```
-* example above requires new system user (`useradd -m rssto`)
-
-3. Run in priority:
-
-  * `systemctl daemon-reload` - reload systemd configuration
-  * `systemctl enable rssto` - enable new service
-  * `systemctl start rssto` - start the process
-  * `systemctl status rssto` - check process launched
+> [!NOTE]
+> Branch in development!
