 ## How can I have different groups of tasks for different hosts with different configurations?
 
+### Simple setup
+
 See [here](https://github.com/anishathalye/dotbot/pull/11#issuecomment-73082152) for information on using machine-specific configs.
 
+### More advanced setup
+
+If you want to install programs independently from a general configuration file, the following setup might be for you.
+
+#### Configurations
+Write a configuration file for each program and put them together in a directory:
+```
+meta/configs/
+├── bash.yaml
+├── git.yaml
+├── i3.yaml
+└── ...
+```
+Then add a basic configuration file (i.e. for cleaning up) at `meta/base.yaml`.
+
+#### Profiles
+Then summarize these configurations in profiles:
+```
+meta/profiles/
+├── server
+├── workstation
+└── ...
+```
+In a profile you specify the configurations you want to install (one per line, without `.yaml`).
+
+#### New `install` scripts
+Then replace the `install` script with the following ones:
+
+##### `install-profile`
+```bash
+#!/usr/bin/env bash
+
+set -e
+
+BASE_CONFIG="base"
+CONFIG_SUFFIX=".yaml"
+
+META_DIR="meta"
+CONFIG_DIR="configs"
+PROFILES_DIR="profiles"
+
+DOTBOT_DIR="dotbot"
+DOTBOT_BIN="bin/dotbot"
+
+BASE_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
+
+
+cd "${BASE_DIR}"
+git submodule update --init --recursive "${DOTBOT_DIR}"
+
+
+while IFS= read -r config; do
+    CONFIGS+=" ${config}"
+done < "${META_DIR}/${PROFILES_DIR}/$1"
+
+shift
+
+
+"${BASE_DIR}/${META_DIR}/${DOTBOT_DIR}/${DOTBOT_BIN}" -d "${BASE_DIR}" -c "${META_DIR}/${BASE_CONFIG}${CONFIG_SUFFIX}"
+
+for config in ${CONFIGS} ${@}; do
+    echo -e "\nConfigure $config"
+    "${BASE_DIR}/${META_DIR}/${DOTBOT_DIR}/${DOTBOT_BIN}" -d "${BASE_DIR}" -c "${META_DIR}/${CONFIG_DIR}/${config}${CONFIG_SUFFIX}"
+done
+```
+
+##### `install-standalone`
+```bash
+#!/usr/bin/env bash
+
+set -e
+
+BASE_CONFIG="base"
+CONFIG_SUFFIX=".yaml"
+
+META_DIR="meta"
+CONFIG_DIR="configs"
+PROFILES_DIR="profiles"
+
+DOTBOT_DIR="dotbot"
+DOTBOT_BIN="bin/dotbot"
+
+BASE_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
+
+
+cd "${BASE_DIR}"
+git submodule update --init --recursive "${DOTBOT_DIR}"
+
+
+"${BASE_DIR}/${META_DIR}/${DOTBOT_DIR}/${DOTBOT_BIN}" -d "${BASE_DIR}" -c "${META_DIR}/${BASE_CONFIG}${CONFIG_SUFFIX}"
+
+for config in ${@}; do
+    "${BASE_DIR}/${META_DIR}/${DOTBOT_DIR}/${DOTBOT_BIN}" -d "${BASE_DIR}" -c "${META_DIR}/${CONFIG_DIR}/${config}${CONFIG_SUFFIX}"
+done
+```
+
+Now you should be able to install a profile with
+```
+./install-profile <profile> [<configs...>]
+```
+and single configurations with
+```
+./install-standalone <configs...>
+```
+
+If you have any open questions or something is unclear, you can try to take a look at a dotfile repository that uses this setup:
+* [vbrandl/dotfiles](https://github.com/vbrandl/dotfiles)
+* [vsund/dotfiles](https://github.com/vsund/dotfiles)
