+## Getting Started
 
+### 1. Install nRF Connect SDK
+
+1. Download and install [nRF Connect for Desktop](https://www.nordicsemi.com/Products/Development-tools/nRF-Connect-for-Desktop)
+2. Open the **Toolchain Manager** inside it
+3. Install **nRF Connect SDK v2.3.0**
+
+### 2. Set up your terminal
+
+Run this every time you open a new terminal:
+
+```bash
+source scripts/env.sh
+```
+
+### 3. Build
+
+```bash
+west build -b nrf9160dk_nrf9160_ns
+```
+
+### 4. Flash
+
+Plug in your nRF9160-DK via USB, then:
+
+```bash
+west flash
+```
+
+### Troubleshooting
+
+Build fails with a cmake cache error - do a clean build:
+```bash
+west build -b nrf9160dk_nrf9160_ns --pristine
+```
+
+`west: command not found` - you forgot to source the env:
+```bash
+source scripts/env.sh
+```
+
+### Editor setup (Neovim + clangd)
+
+Run this once after cloning to generate `compile_commands.json` for LSP support:
+
+```bash
+source scripts/env.sh
+west build -b nrf9160dk_nrf9160_ns -- -DCMAKE_EXPORT_COMPILE_COMMANDS=ON
+```
+
+The `.clangd` config is already in the repo, clangd picks it up from there.
 
 ## MQTT Data format
 When sending data over mqtt the following format is used to send a comma separated string to save as much data as possible.
