-feature.*::
-	The config settings that start with `feature.` modify the defaults of
-	a group of other config settings. These groups are created by the Git
-	developer community as recommended defaults and are subject to change.
-	In particular, new config options may be added with different defaults.
-
-feature.experimental::
-	Enable config options that are new to Git, and are being considered for
-	future defaults. Config settings included here may be added or removed
-	with each release, including minor version updates. These settings may
-	have unintended interactions since they are so new. Please enable this
-	setting if you are interested in providing feedback on experimental
-	features. The new default values are:
-+
-* `pack.useSparse=true` uses a new algorithm when constructing a pack-file
-which can improve `git push` performance in repos with many files.
-+
-* `fetch.negotiationAlgorithm=skipping` may improve fetch negotiation times by
-skipping more commits at a time, reducing the number of round trips.
-+
-* `fetch.writeCommitGraph=true` writes a commit-graph after every `git fetch`
-command that downloads a pack-file from a remote. Using the `--split` option,
-most executions will create a very small commit-graph file on top of the
-existing commit-graph file(s). Occasionally, these files will merge and the
-write may take longer. Having an updated commit-graph file helps performance
-of many Git commands, including `git merge-base`, `git push -f`, and
-`git log --graph`.
-
-feature.manyFiles::
-	Enable config options that optimize for repos with many files in the
-	working directory. With many files, commands such as `git status` and
-	`git checkout` may be slow and these new defaults improve performance:
-+
-* `index.version=4` enables path-prefix compression in the index.
-+
-* `core.untrackedCache=true` enables the untracked cache. This setting assumes
-that mtime is working on your machine.
