Translation update

Syncthing should not try to start a browser when invoked by systemd.
Furthermore we do not need any timestamps in the journal as systemd
already handles this for us.

 ## Contributing Code
 
 Every contribution is welcome. If you want to contribute but are unsure
-where to start, any open issues are fair game! See the [Contribution
-Guidelines](http://docs.syncthing.net/dev/contributing.html) for the full
-story on committing code.
+where to start, any open issues are fair game! Be prepared for a
+[certain amount of review](https://github.com/syncthing/syncthing/wiki/FAQ#why-are-you-being-so-hard-on-my-pull-request);
+it's all in the name of quality. :) Following the points below will make this
+a smoother process.
 
-## Contributing Documentation
+Individuals making significant and valuable contributions are given
+commit-access to the project. If you make a significant contribution and
+are not considered for commit-access, please contact any of the
+Syncthing core team members.
 
-Updates to the [documentation site](http://docs.syncthing.net/) can be
-made as pull requests on the [documentation
-repository](https://github.com/syncthing/docs).
+All nontrivial contributions should go through the pull request
+mechanism for internal review. Determining what is "nontrivial" is left
+at the discretion of the contributor.
+
+### Authorship
+
+All code authors are listed in the AUTHORS file. Commits must be made
+with the same name and email as listed in the AUTHORS file. To
+accomplish this, ensure that your git configuration is set correctly
+prior to making your first commit;
+
+    $ git config --global user.name "Jane Doe"
+    $ git config --global user.email janedoe@example.com
+
+You must be reachable on the given email address. If you do not wish to
+use your real name for whatever reason, using a nickname or pseudonym is
+perfectly acceptable.
+
+### Core Team
+
+The Syncthing core team currently consists of the following members;
+
+ - Jakob Borg (@calmh)
+ - Audrius Butkevicius (@AudriusButkevicius)
+
+## Coding Style
+
+- Follow the conventions laid out in [Effective Go](https://golang.org/doc/effective_go.html)
+  as much as makes sense.
+
+- All text files use Unix line endings.
+
+- Each commit should be `go fmt` clean.
+
+- The commit message subject should be a single short sentence
+  describing the change, starting with a capital letter.
+
+- Commits that resolve an existing issue must include the issue number
+  as `(fixes #123)` at the end of the commit message subject.
+
+- Imports are grouped per `goimports` standard; that is, standard
+  library first, then third party libraries after a blank line.
+
+- A contribution solving a single issue or introducing a single new
+  feature should probably be a single commit based on the current
+  `master` branch. You may be asked to "rebase" or "squash" your pull
+  request to make sure this is the case, especially if there have been
+  amendments during review.
 
 ## Licensing

+## Building
+
+[See the documentation](https://github.com/syncthing/syncthing/wiki/Building)
+on how to get started with a build environment.
+
+## Branches
+
+ - `master` is the main branch containing good code that will end up in
+   the next release. You should base your work on it. It won't ever be
+   rebased or force-pushed to.
+
+ - `vx.y` branches exist to make patch releases on otherwise obsolete
+   minor releases. Should only contain fixes cherry picked from master.
+   Don't base any work on them.
+
+ - Other branches are probably topic branches and may be subject to
+   rebasing. Don't base any work on them unless you specifically know
+   otherwise.
+
+## Tags
+
+All releases are tagged semver style as `vx.y.z`. Release tags are
+signed by GPG key BCE524C7.
+
+## Tests
+
+Yes please!

-==========
-
-![travis build status](https://travis-ci.org/rcrowley/go-metrics.svg?branch=master)
-
-Go port of Coda Hale's Metrics library: <https://github.com/dropwizard/metrics>.
-
-Documentation: <http://godoc.org/github.com/rcrowley/go-metrics>.
-
-Usage
------
-
-Create and update metrics:
-
-```go
-c := metrics.NewCounter()
-metrics.Register("foo", c)
-c.Inc(47)
-
-g := metrics.NewGauge()
-metrics.Register("bar", g)
-g.Update(47)
-
-s := metrics.NewExpDecaySample(1028, 0.015) // or metrics.NewUniformSample(1028)
-h := metrics.NewHistogram(s)
-metrics.Register("baz", h)
-h.Update(47)
-
-m := metrics.NewMeter()
-metrics.Register("quux", m)
-m.Mark(47)
-
-t := metrics.NewTimer()
-metrics.Register("bang", t)
-t.Time(func() {})
-t.Update(47)
-```
-
-Periodically log every metric in human-readable form to standard error:
-
-```go
-go metrics.Log(metrics.DefaultRegistry, 60e9, log.New(os.Stderr, "metrics: ", log.Lmicroseconds))
-```
-
-Periodically log every metric in slightly-more-parseable form to syslog:
-
-```go
-w, _ := syslog.Dial("unixgram", "/dev/log", syslog.LOG_INFO, "metrics")
-go metrics.Syslog(metrics.DefaultRegistry, 60e9, w)
-```
-
-Periodically emit every metric to Graphite using the [Graphite client](https://github.com/cyberdelia/go-metrics-graphite):
-
-```go
-
-import "github.com/cyberdelia/go-metrics-graphite"
-
-addr, _ := net.ResolveTCPAddr("tcp", "127.0.0.1:2003")
-go graphite.Graphite(metrics.DefaultRegistry, 10e9, "metrics", addr)
-```
-
-Periodically emit every metric into InfluxDB:
-
-**NOTE:** this has been pulled out of the library due to constant fluctuations
-in the InfluxDB API. In fact, all client libraries are on their way out. see
-issues [#121](https://github.com/rcrowley/go-metrics/issues/121) and
-[#124](https://github.com/rcrowley/go-metrics/issues/124) for progress and details.
-
-```go
-import "github.com/rcrowley/go-metrics/influxdb"
-
-go influxdb.Influxdb(metrics.DefaultRegistry, 10e9, &influxdb.Config{

-
-Periodically upload every metric to Librato using the [Librato client](https://github.com/mihasya/go-metrics-librato):
-
-**Note**: the client included with this repository under the `librato` package
-has been deprecated and moved to the repository linked above.
-
-```go
-import "github.com/mihasya/go-metrics-librato"
-
-go librato.Librato(metrics.DefaultRegistry,
-    10e9,                  // interval
-    "example@example.com", // account owner email address
-    "token",               // Librato API token
-    "hostname",            // source
-    []float64{0.95},       // percentiles to send
-    time.Millisecond,      // time unit
-)
-```
-
-Periodically emit every metric to StatHat:
-
-```go
-import "github.com/rcrowley/go-metrics/stathat"
-
-go stathat.Stathat(metrics.DefaultRegistry, 10e9, "example@example.com")
-```
-
-Installation
-------------
-
-```sh
-go get github.com/rcrowley/go-metrics
-```
-
-StatHat support additionally requires their Go client:
-
-```sh
-go get github.com/stathat/go
-```
-
