Paths
-----
Locations:

* `bin`   - Compiled binaries
* `share` - Distributed read-only data
* `user`  - User-created modifiable data

Where each location is on each platform:

* Windows .zip / RUN_IN_PLACE source:
    * `bin`   = `bin`
    * `share` = `.`
    * `user`  = `.`
* Windows installed:
    * `bin`   = `C:\Program Files\Minetest\bin (Depends on the install location)`
    * `share` = `C:\Program Files\Minetest (Depends on the install location)`
    * `user`  = `%APPDATA%\Minetest` or `%MINETEST_USER_PATH%`
* Linux installed:
    * `bin`   = `/usr/bin`
    * `share` = `/usr/share/minetest`
    * `user`  = `~/.minetest` or `$MINETEST_USER_PATH`
* macOS:
    * `bin`   = `Contents/MacOS`
    * `share` = `Contents/Resources`
    * `user`  = `Contents/User` or `~/Library/Application Support/minetest` or `$MINETEST_USER_PATH`

Worlds can be found as separate folders in: `user/worlds/`

Configuration file
------------------
- Default location:
    `user/minetest.conf`
- This file is created by closing Minetest for the first time.
- A specific file can be specified on the command line:
    `--config <path-to-file>`
- A run-in-place build will look for the configuration file in
    `location_of_exe/../minetest.conf` and also `location_of_exe/../../minetest.conf`

Command-line options
--------------------
- Use `--help`

Compiling
---------

- [Compiling on GNU/Linux](doc/compiling/linux.md)
- [Compiling on Windows](doc/compiling/windows.md)
- [Compiling on MacOS](doc/compiling/macos.md)

Docker
------

- [Developing minetestserver with Docker](doc/developing/docker.md)

We provide Minetest server Docker images using the GitLab mirror registry.

Images are built on each commit and available using the following tag scheme:

* `registry.gitlab.com/minetest/minetest/server:latest` (latest build)
* `registry.gitlab.com/minetest/minetest/server:<branch/tag>` (current branch or current tag)
* `registry.gitlab.com/minetest/minetest/server:<commit-id>` (current commit id)

If you want to test it on a Docker server you can easily run:

	sudo docker run registry.gitlab.com/minetest/minetest/server:<docker tag>

If you want to use it in a production environment you should use volumes bound to the Docker host
to persist data and modify the configuration:

	sudo docker create -v /home/minetest/data/:/var/lib/minetest/ -v /home/minetest/conf/:/etc/minetest/ registry.gitlab.com/minetest/minetest/server:master

Data will be written to `/home/minetest/data` on the host, and configuration will be read from `/home/minetest/conf/minetest.conf`.

**Note:** If you don't understand the previous commands please read the official Docker documentation before use.

You can also host your Minetest server inside a Kubernetes cluster. See our example implementation in [`misc/kubernetes.yml`](misc/kubernetes.yml).


Version scheme
--------------
We use `major.minor.patch` since 5.0.0-dev. Prior to that we used `0.major.minor`.

- Major is incremented when the release contains breaking changes, all other
numbers are set to 0.
- Minor is incremented when the release contains new non-breaking features,
patch is set to 0.
- Patch is incremented when the release only contains bugfixes and very
minor/trivial features considered necessary.

Since 5.0.0-dev and 0.4.17-dev, the dev notation refers to the next release,
i.e.: 5.0.0-dev is the development version leading to 5.0.0.
Prior to that we used `previous_version-dev`.
