-shell-ci-build [![Build Status](https://travis-ci.org/caarlos0/shell-ci-build.svg?branch=master)](https://travis-ci.org/caarlos0/shell-ci-build)
-==================
-
-A submodule to lint your shell projects with shellcheck in travis.ci builds.
-
-## Build
-
-- The `install.sh` script will install shellckeck.
-- The `build.sh` will lint all executable files with shellcheck, avoiding
-Ruby, compdef and the like files. It will also ignore all files inside `.git`
-directory and files of your `gitmodules`, if any.
-
-## Usage
-
-```sh
-git submodule add https://github.com/caarlos0/shell-ci-build.git build
-cp build/travis.yml.example .travis.yml
-```
-
-We also support Shippable:
-
-```
-cp build/shippable.yml.example .shippable.yml
-```
-
-Or tweak your `.travis.yml` to be like this:
-
-```yml
-language: bash
-install:
-  - ./build/install.sh
-script:
-  - ./build/build.sh
-```
-
-## Customizing
-
-You might want to lint other files, to do that, you need your own
-`build.sh` and a slight change in `.travis.yml` file.
-
-Example (from  my [dotfiles](https://github.com/caarlos0/dotfiles)):
-
-```sh
-#!/usr/bin/env bash
-set -eo pipefail
-source ./build/build.sh
-check "./zsh/zshrc.symlink"
-```
-
-```yml
-language: bash
-install:
-  - ./build/install.sh
-script:
-  - ./build.sh
-notifications:
-  email: false
-```
-
-This will make travis ran the `build.sh` from this project first,
-then, lint your custom files.
-
-You can also override the `find_cmd` function, which returns a string
-containing the `find` command to `eval`. Check the source or open an
-issue if you have any problems.
-
-## Updating
-
-Update your projects is easy. Just run this:
-
-```sh
-git submodule update --remote --merge && \
-  git commit -am 'updated shell-ci-build version' && \
-  git push
-```
