+# Docker
+Docker is a project that helps develop, update and publish Docker images for Foliant.
+
+## Overview
+There are four Docker images to build different versions of Foliant. 
+This repo contains Dockerfiles to build each Docker image. 
+Also,
+each Dockerfile has its own build-and-publish script
+to publish images to [Docker Hub](https://hub.docker.com/r/foliant/foliant/tags).
+
+## header
+
+* `foliant/foliant:slim` — minimal image of Foliant core with no extensions.
+  * [Dockerfile-slim](https://github.com/foliant-docs/docker/blob/master/Dockerfile-slim)
+  * [build_slim.sh](https://github.com/foliant-docs/docker/blob/master/build_slim.sh)
+
+* `foliant/foliant` — the default image with Foliant core and the foliantcontrib.init extension
+  * [Dockerfile](https://github.com/foliant-docs/docker/blob/master/Dockerfile)
+  * [build_latest.sh](https://github.com/foliant-docs/docker/blob/master/build_latest.sh)
+* `foliant/foliant:pandoc` — the image with foliantcontrib.pandoc and its dependencies:
+TexLive and Pandoc for building PDF and DOCX
+  * [Dockerfile-pandoc](https://github.com/foliant-docs/docker/blob/master/Dockerfile-pandoc)
+  * [build_pandoc.sh](https://github.com/foliant-docs/docker/blob/master/build_pandoc.sh)
+* `foliant/foliant:full` — the full image with all official Foliant extensions and third-party tools required for them to work
+  * [Dockerfile-full](https://github.com/foliant-docs/docker/blob/master/Dockerfile-full)
+  * [build_full.sh](https://github.com/foliant-docs/docker/blob/master/build_full.sh)
+
+* [Makefile](https://github.com/foliant-docs/docker/blob/master/Makefile) needed to build Docker images on local computer
+
+## Docker images dependencies
+
+Docker images build with Dockerfiles based on a previous light version in the following order:
+> Dockerfile-slim → Dockerfile → Dockerfile-pandoc → Dockerfile-full
+
+It means that if you update `foliant/foliant:slim`, you should update all its dependants after:
+`foliant/foliant` then `foliant/foliant:pandoc` then `foliant/foliant:full`. If you want to update `foliant/foliant`,
+you should update `foliant/foliant:pandoc` then `foliant/foliant:full` etc.
+
+### Which image to update?
+
+* When [Foliant-core](https://github.com/foliant-docs/foliant) updates: 
+   > update `foliant/foliant:slim` → `foliant/foliant` → `foliant/foliant:pandoc` → `foliant/foliant:full`
+
+* When [foliantcontrib.init](https://github.com/foliant-docs/foliantcontrib.init) updates:
+   > update `foliant/foliant` → `foliant/foliant:pandoc` → `foliant/foliant:full`
+
+* When [foliantcontrib.pandoc](https://github.com/foliant-docs/foliantcontrib.pandoc) updates: 
+   > update `foliant/foliant:pandoc` → `foliant/foliant:full`
+
+* When any other Foliant extension updates: 
+   > update `foliant/foliant:full` and [requirements.txt](https://github.com/foliant-docs/docker/blob/master/dependency_files/python_packages/requirements.txt) 
+   > from `dependency_files/python_packages/requirements.txt`
+
+## Update procedure
+To update Docker-image on Docker Hub, you should:
+1. Clone, pull or download this repo on your computer.
+2. Update dependencies if needed.
+3. Push changes to this repo.
+4. Run a script which related to Docker-image you needed:
+
+```bash
+# In the project directory
+
+./build_slim.sh    # for foliant/foliant:slim
+./build_latest.sh  # for foliant/foliant
+./build_pandoc.sh  # for foliant/foliant:pandoc
+./build_full.sh    # for foliant/foliant:full
+```
+
+#### How to tag image (optional)
+Scripts set tag for published image automatically. But you can tag the image manually as a script parameter:
+```bash
+./build_full.sh 1.0.13
+```
+
+#### Docker Hub authorization
+To push images to the [Foliant project on Docker Hub](https://hub.docker.com/r/foliant/foliant/),
+you need an account on Docker Hub with appropriate rights.
