-
-There are basically two ways to contribute code to this project: Either via GitLab or via e‑mail. The first one is probably easier for most people. However
-it requires a account at GitLab.com. For people who don’t want to create an account—or have any other reason to not use GitLab—e‑mail is an alternative option.
-
-h2. Contributing via GitLab
-
-Create an account on GitLab.com or use your already existing account. Fork this repository inside GitLab, add changes to your fork and finally create a Merge Request to contribute your changes back to this repository.
-
-h2. Contributing via E‑mail
-
-To contribute via e‑mail, first clone this repository to your local harddrive. After adding changes to your local copy you have two options to send them back to this repository: as patch or as Pull Request
-
-h3. E‑mail Patch
-
-To send a patch with your changes, use git’s @send-email@ option as explained in "Public Project over Email":https://git-scm.com/book/en/v2/Distributed-Git-Contributing-to-a-Project#_project_over_email of section "5.2 Distributed Git - Contributing to a Project":https://git-scm.com/book/en/v2/Distributed-Git-Contributing-to-a-Project of the "Git Pro Book":https://git-scm.com/book/en/v2/.

-h2. Building
-
-Build the application with _setuptools_:
-
-bc. $ python3 setup.py build
-
-
-h2. Running/Testing
-
-For testing the application and running it without (system-wide) installation, donwload/clone the code, build it as described above and then use _setuptools_ to install it for the current user:
-
-bc. $ python3 setup.py develop --user
-
-After that you can run it with
-
-bc. $ ~/.local/bin/mcg
-
-or if _~/.local/bin/_ is on your PATH
-
-bc. $ mcg
-
-
-h2. Installing
-
-Install the application system-wide with _setuptools_:
-
-bc. # python3 setup.py install
-
-Note: _On Linux using the distribution’s package manager is the preferred way of installing applications system-wide._
-
-
-h2. Packaging
-
-Create a distribution package with _setuptools_:
-
-bc. $ python3 setup.py sdist
-
-
-h2. Cover/image configuration
-
-Since MPD itself does not provide the cover/image/album art binaries, yet, _mcg_ has to look for them itself. In order to find the images a base folder has to be configured on the Connection tab as “Image Directory”. This value can either be a local (absolute) folder (e. g. /home/user/music/) or an http URL (e. g. http://localhost/music/). _mcg_ then adds the (relative) folder of the audio file to this paths and tries different names for the actual file:
-
-# the album name
-# “cover”
-# “folder”
-
-The following file extensions are used:
-
-# png
-# jpg
-
-The first combination that results in an existing file is used as cover image. If no matching file exists, _mcg_ will try to traverse the directory for any image file as fallback—this is done for local paths only though, not for http URLs.
