+This is directory which stores Go modules with pinned buildable package that is used within this repository, managed by https://github.com/bwplotka/bingo.
+
+* Run `bingo get` to install all tools having each own module file in this directory.
+* Run `bingo get <tool>` to install <tool> that have own module file in this directory.
+* For Makefile: Make sure to put `include .bingo/Variables.mk` in your Makefile, then use $(<upper case tool name>) variable where <tool> is the .bingo/<tool>.mod.
+* For shell: Run `source .bingo/variables.env` to source all environment variable for each tool.
+* For go: Import `.bingo/variables.go` to for variable names.
+* See https://github.com/bwplotka/bingo or -h on how to add, remove or change binaries dependencies.

+## Requirements
