+
+## Overview
+There is a few parts:
+1. An implementation of homebrew dmr protocol (which is used by brandmeister and hblink). Not yet complete, but sufficient for #2 and #3.
+1. Decoding UDP proxy
+1. Basic private dmr master server
+
+### Installation
+1. Check basic requirements:
+    - Linux or Windows
+    - Python 3.13+
+1. Clone/download the repo.
+1. Execute (linux example):
+```
+$ python -m venv venv
+$ . venv/bin/activate
+$ python -m pip install --upgrade pip
+$ pip install -r requirements.txt
+```
+
+### Configuration
+Copy `localmaster_EXAMPLE.py` to `localmaster.py` and edit.
+
+### Run
+```
+$ . venv/bin/activate
+$ python localmaster.py
+```
+`Ctrl+C` to break and stop.
+
+The running server listens for `62031/udp` as DMR service (may be changed with `--port` command line argument)
+and exposes http API/dashboard on `8000/tcp` (may be changed with `--web-port` command line argument):
+- API: http://YOUR-SERVER-IP:8000/api/dashboard
+- Web dashboard: http://YOUR-SERVER-IP:8000/dashboard/index.html
+
+
+
+## Roadmap
+### What is this for (general TODO)
+- Private dmr network (own registration, admintool, dashboard, voice apps, etc)
+- Other dmr networks bridge (configurable group/unit routing rules, ID replacements, etc)
+- Bridge/proxy with packet modification (substitute IDs, add TA, etc..)
+- Voice robots interface at packet level (parrot for group and unit cals, recording/playback as prewritten packets by events)
+- Encoding and decoding of AMBE (allows to build advanced voice services, like voice time, agenda, etc)
+- Voice call history dump (ambe files or decoded)
+
+
+### Features & TODO
+- ✔️ basic apps support
+- ✔️ parrot
+- ✔️ password check
+- ✔️ fastapi api
+- ✔️ web dashboard
+- ✔️ unit call routing
+- ✔️ allow single peer id check
+- ✔️ TA support (DMRA packet)
+- 🥕 routing entity (1 timeslot == 1 routing entity)
+- 🥕 only one call per ts for peer (per routing entity)
+- 🥕 apps unit call routing (routing entity for app)
+- 🥕 configuration
+- 🥕 users configuration (allowed id and passes per id)
+- 🥕 resolve id to callsigns
+- 🥕 routing 2: group subscriptions
+- 🥕 data calls (messages)
+- 🥕 dmr internal burst structure decoding (to fix rf fields and get ambe)
+- 🥕 ambe decode/encode
+- 🥕 log voice calls as files
+- 🥕 TA support 2 (inside DMRD packets)
+- 🥕 registration
+- 🥕 update radiod list and resolve
