-The document has been moved [here](https://docs.victoriametrics.com/contributing/).
+If you like VictoriaMetrics and want to contribute, then we need the following:
+
+- Filing issues and feature requests [here](https://github.com/VictoriaMetrics/VictoriaMetrics/issues).
+- Spreading a word about VictoriaMetrics: conference talks, articles, comments, experience sharing with colleagues.
+- Updating documentation.
+
+We are open to third-party pull requests provided they follow [KISS design principle](https://en.wikipedia.org/wiki/KISS_principle):
+
+- Prefer simple code and architecture.
+- Avoid complex abstractions.
+- Avoid magic code and fancy algorithms.
+- Avoid [big external dependencies](https://medium.com/@valyala/stripping-dependency-bloat-in-victoriametrics-docker-image-983fb5912b0d).
+- Minimize the number of moving parts in the distributed system.
+- Avoid automated decisions, which may hurt cluster availability, consistency or performance.
+
+Adhering `KISS` principle simplifies the resulting code and architecture, so it can be reviewed, understood and verified by many people.

-# vlogsgenerator
-
-Logs generator for [VictoriaLogs](https://docs.victoriametrics.com/victorialogs/).
-
-## How to build vlogsgenerator?
-
-Run `make vlogsgenerator` from the repository root. This builds `bin/vlogsgenerator` binary.
-
-## How run vlogsgenerator?
-
-`vlogsgenerator` generates logs in [JSON line format](https://jsonlines.org/) suitable for the ingestion
-via [`/insert/jsonline` endpoint at VictoriaLogs](https://docs.victoriametrics.com/victorialogs/data-ingestion/#json-stream-api).
-
-By default it writes the generated logs into `stdout`. For example, the following command writes generated logs to `stdout`:
-
-```
-bin/vlogsgenerator
-```
-
-It is possible to redirect the generated logs to file. For example, the following command writes the generated logs to `logs.json` file:
-
-```
-bin/vlogsgenerator > logs.json
-```
-
-The generated logs at `logs.json` file can be inspected with the following command:
-
-```
-head logs.json | jq .
-```
-
-Below is an example output:
-
-```json

-
-The `run_id` field uniquely identifies every `vlogsgenerator` invocation.
-
-### How to write logs to VictoriaLogs?
-
-The generated logs can be written directly to VictoriaLogs by passing the address of [`/insert/jsonline` endpoint](https://docs.victoriametrics.com/victorialogs/data-ingestion/#json-stream-api)
-to `-addr` command-line flag. For example, the following command writes the generated logs to VictoriaLogs running at `localhost`:
-
-```
-bin/vlogsgenerator -addr=http://localhost:9428/insert/jsonline
-```
-
-### Configuration
-
-`vlogsgenerator` accepts various command-line flags, which can be used for configuring the number and the shape of the generated logs.
-These flags can be inspected by running `vlogsgenerator -help`. Below are the most interesting flags:
-
-* `-start` - starting timestamp for generating logs. Logs are evenly generated on the [`-start` ... `-end`] interval.
-* `-end` - ending timestamp for generating logs. Logs are evenly generated on the [`-start` ... `-end`] interval.
-* `-activeStreams` - the number of active [log streams](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields) to generate.
-* `-logsPerStream` - the number of log entries to generate per each log stream. Log entries are evenly distributed on the [`-start` ... `-end`] interval.
-
-The total number of generated logs can be calculated as `-activeStreams` * `-logsPerStream`.
-
-For example, the following command generates `1_000_000` log entries on the time range `[2024-01-01 - 2024-02-01]` across `100`
-[log streams](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields), where every logs stream contains `10_000` log entries,
-and writes them to `http://localhost:9428/insert/jsonline`:
-
-```
-bin/vlogsgenerator \
-  -start=2024-01-01 -end=2024-02-01 \
-  -activeStreams=100 \
-  -logsPerStream=10_000 \
-  -addr=http://localhost:9428/insert/jsonline
-```
-
-### Churn rate
-
-It is possible to generate churn rate for active [log streams](https://docs.victoriametrics.com/victorialogs/keyconcepts/#stream-fields)
-by specifying `-totalStreams` command-line flag bigger than `-activeStreams`. For example, the following command generates
-logs for `1000` total streams, while the number of active streams equals to `100`. This means that at every time there are logs for `100` streams,
-but these streams change over the given [`-start` ... `-end`] time range, so the total number of streams on the given time range becomes `1000`:
-
-```
-bin/vlogsgenerator \
-  -start=2024-01-01 -end=2024-02-01 \
-  -activeStreams=100 \
-  -totalStreams=1_000 \
-  -logsPerStream=10_000 \
-  -addr=http://localhost:9428/insert/jsonline
-```
-
-In this case the total number of generated logs equals to `-totalStreams` * `-logsPerStream` = `10_000_000`.
-
-### Benchmark tuning
-
-By default `vlogsgenerator` generates and writes logs by a single worker. This may limit the maximum data ingestion rate during benchmarks.
-The number of workers can be changed via `-workers` command-line flag. For example, the following command generates and writes logs with `16` workers:
-
-```
-bin/vlogsgenerator \
-  -start=2024-01-01 -end=2024-02-01 \
-  -activeStreams=100 \
-  -logsPerStream=10_000 \
-  -addr=http://localhost:9428/insert/jsonline \
-  -workers=16
-```
-
-### Output statistics
-
-Every 10 seconds `vlogsgenerator` writes statistics about the generated logs into `stderr`. The frequency of the generated statistics can be adjusted via `-statInterval` command-line flag.
-For example, the following command writes statistics every 2 seconds:
-
-```
-bin/vlogsgenerator \
-  -start=2024-01-01 -end=2024-02-01 \
-  -activeStreams=100 \
-  -logsPerStream=10_000 \
-  -addr=http://localhost:9428/insert/jsonline \
-  -statInterval=2s
-```
