 ### Dataset Summary
 
-VoxDIY RusNews is a dataset for crowdsourced text aggregation collected via VoxDIY pipeline. RusNews dataset was used as a source for the speech generation step.
+VoxDIY RusNews is the first publicly available large-scale dataset of crowdsourced audio transcriptions in Russian language.
+The dataset was constructed by annotating audio recordings of Russian sentences from news domain on [Toloka crowdsourcing platform](https://toloka.ai).
+VoxDIY RusNews consists of 3091 instances having around 21K annotations obtained from crowd workers.
+
+### Supported Tasks and Leaderboards
+Aggregation of crowd transcriptions.
+
+### Languages
+Russian
+
+## Dataset Structure
+
+### Data Instances
+
+A data instance contains a url to the audio recording, a list of transcriptions along with the corresponding performers identifiers and 
+ground truth. For each data instance, seven crowdsourced transcriptions are provided.
+
+```

+
+### Data Fields
+
+* task: a string containing a url of the audio recording
+* transcriptions: a list of the crowdsourced transcriptions separated by '|'
+* performers: the corresponding performers' identifiers.
+* gt: ground truth transcription
+
+## Dataset Creation
+
+### Source Data
+
+The audio recordings were obtained using a [speech synthesis tool](https://cloud.yandex.com/en-ru/services/speechkit).
+The source sentences come from the Russian test set of the machine translation shared task executed as a part of the 
+Eights and Ninth Workshops on Statistical Machine Translation ([WMT 2013](https://www.statmt.org/wmt13/) and [WMT 2014](https://www.statmt.org/wmt14/)).
+
+### Annotations
+
+Annotation was done on [Toloka crowdsourcing platform](https://toloka.ai) with overlap of 7 (that is, each task was performed by 7 annotators).
+
+Only annotators who self-reported the knowledge of Russian had access to the annotation task.
+Additionally, annotators had to pass *Entrance Exam*. For this, we ask all incoming eligible workers to annotate ten audio
+recordings. We then compute our target metric — Word Error Rate (WER) — on these recordings and accept to the main task all workers 
+who achieve WER of 40% or less (the smaller the value of the metric, the higher the quality of annotation).
+
+The Toloka crowdsourcing platform associates workers with unique identifiers and returns these identifiers to the requester. 
+To further protect the data, we additionally encode each identifier with an integer that is eventually reported in our released datasets.
