-### Requirements
\ No newline at end of file
+### Requirements
+- Meshtastic device
+    - _RAK WISBlock_ & _Heltec V3_ will be supported on my end
+- Linux machine running Debian
+- `apt` as package manager
+- `systemd` as init system
+
+I will try to broaden the range of host os possibilities along the way
+
+## Development Setup
+
+1. Setup 64bit Linux Debian on host machine
+2. Install git:
+```bash
+sudo apt install -y git
+```
+3. Clone repository
+```bash
+git clone https://lab.c95.org/fr4nz/LoMeS.git && cd LoMeS
+```
+4. Run development environment setup
+```bash
+chmod +x lomes-setup.sh && sudo ./lomes-setup.sh
+```
+5. Start developing
+
+## What does the script do?
+
+1. checks for `sudo` or `root` privileges
+2. searches & installs missing dependencies | cmd `apt`
+3. gets some ID from your system (ip, network interface, hostname) | cmd `ip` & `hostname`
+4. lets you change hostname (optional | reboot needed) | cmd `sed`
+5. creates a certificate for `nginx` | cmd `mkdir`, `openssl`, `chmod` & `cp`
+6. edits `nginx.conf` (domain, ip, cert & key path) | cmd `sed`
+7. removes default nginx welcome page | cmd `rm`
+8. checks `nginx.conf` & reloads nginx | cmd `nginx` 
+9. reviews `log  |  /tmp/LoMeS/install_log` for errors
+10. asks to start flask | cmd `flask` **OR** reboot if `hostname` changed | cmd `reboot`
