 # Dotfiles
 
 In this repo I store my config files.
-- `Brewfile` for macOS (I'm about to drop it).
-- `configuration.nix` for NixOS (a new linux distro for me, that I'm exploring as a replacement for macOS).
-It helps me to install quickly all software I need for work and fun.
+It helps me to install quickly all software I need for work and fun.  
 Feel free to check & alter the list of software to be installed in these files.
 
-## Installation
+I use NixOS. It stores all of it's configuration in `configuration.nix`.
+That's where you can start exploration and modification.
 
-### macOS/Brew
-1. Install Brew from here: https://brew.sh/
-2. Copy Brewfile to your computer and run `brew bundle` from the same folder where you copied the file.
-3. Run `chmod +x ./cron-adjust-microphone-gain-to-100.sh` and `./cron-adjust-microphone-gain-to-100.sh` [to change microphone gain to 100% on macOS](https://apple.stackexchange.com/questions/97810/mac-osx-microphone-input-volume-level-auto-adjusts-can-it-be-disabled).
+## Install
 
-Note: Brew will ask you for the root password and other apps inside Brewfile might ask you for your password as well.  
-Usually installation takes 10-20 min, so make sure to brew a cup of tea or coffee :)
-
-### NixOS
-1. `chmod +x ./build-nix.sh`
+1. Clone this repo.
+2. Give build script permission to execute: `chmod +x ./build-nix.sh`.
 2. [Optionally] SSH Config `cp ./ssh-config.nix.example ./ssh-config.nix` and fill with your values.
-3. [First run] `./build-nix.sh` or [then] just `make`
\ No newline at end of file
+3. Apply configuration with `make`.
+
+## Usage
+
+1. Change configuration files to desired state.
+2. Apply configuration with `make`.
