 # CounterQuant CS2 Demos
 
-Raw CS2 (Counter-Strike 2) demo files (.dem) collected from HLTV — the authoritative competitive CS2 demo repository.
+**Raw professional CS2 (Counter-Strike 2) demo files (.dem)** collected from HLTV.org — the largest open collection of competitive CS2 demos.
+
+**Curated and maintained by Eimantas Kulbe (KEDevO)** as part of the [CounterQuant](https://cs2quant.kedevo.com) esports analytics project.

 ## Dataset Goal
 
-Provide the CS2 research community with the largest open-access collection of raw professional demo files, covering all competitive tiers from CS:GO's origin through CS2's present day.
+Provide the research and analytics community with **the most complete open-access archive** of professional CS2 demo files.
 
-**The philosophy:** squeeze every available demo into one place so anyone can preprocess, parse, or derive features in any way they want — no gatekeeping, no preprocessing lock-in.
+**Philosophy**: No gatekeeping. Raw demos only — parse and derive features however you want.

-## Usage
+---
 
-### Parse with demoparser2 (Python)
+## File Structure
 
-```python
-from demoparser2 import DemoParser
+```bash
+data/
+├── 2024/
+│   ├── tier1/
+│   │   └── {match_id}/
+│   │       └── {map_name}.dem
+│   └── tier2/
+├── 2025/
+│   ├── tier1/
+│   └── tier2/
+└── ...
+```
 
-parser = DemoParser("data/2024/tier1/2378549/astralis-vs-natus-vincere.dem")
+**Example**:
+- `data/2025/tier1/2401337/vitality-vs-g2-inferno.dem`
 
-# Player kill events
-kills = parser.parse_event("player_death", player=["name", "team_name"])
+---
 
-# Round-by-round economy
-rounds = parser.parse_ticks(["total_rounds_played", "cash_spent_t", "cash_spent_ct"])
-```
+## Quick Usage
 
-### Download via huggingface_hub
+### 1. Download specific tiers/years (Recommended)
 
 ```python
 from huggingface_hub import snapshot_download
 
-# Download all 2024 T1 demos
+# Download only 2025 Tier 1 demos
 path = snapshot_download(
     repo_id="KEDevO/CounterQuant-CS2-Demos",
     repo_type="dataset",
-    allow_patterns="data/2024/tier1/**",
-    local_dir="./demos",
+    allow_patterns="data/2025/tier1/**",
+    local_dir="./cs2_demos",
+    # resume_download=True
 )
 ```
 
-### Stream individual files
+### 2. Parse demos with demoparser2
+
+```python
+from demoparser2 import DemoParser
+
+parser = DemoParser("data/2025/tier1/2401337/vitality-vs-g2-inferno.dem")
+
+kills = parser.parse_event("player_death")
+rounds = parser.parse_ticks(["total_rounds_played", "cash_spent_t", "cash_spent_ct"])
+```
+
+### 3. Download single file
 
 ```python
 from huggingface_hub import hf_hub_download
 
-dem = hf_hub_download(
+hf_hub_download(
     repo_id="KEDevO/CounterQuant-CS2-Demos",
-    repo_type="dataset",
-    filename="data/2024/tier1/2378549/match.dem",
+    filename="data/2025/tier1/2401337/vitality-vs-g2-inferno.dem",
+    repo_type="dataset"
 )
 ```
 
-## What You Can Do With These Demos
+---
+
+## What You Can Build With This Dataset
 
-- **Feature engineering**: extract round economy, positioning, utility, player rating
-- **Model training**: win-probability, player rating, team strength models
-- **Research**: CS2 game theory, tactical analysis, team dynamics
-- **Statistics**: compute your own KDA, HLTV Rating 2.0, ADR, Impact
-- **No restrictions**: raw bytes, parse however you like
+- Advanced player/team feature engineering
+- Win-probability & clutch models
+- Chemistry / synergy metrics
+- Utility usage & positioning analysis
+- Custom rating systems (better than HLTV Rating 2.0)
+- Tactical & game-theory research
 
-## Update Schedule
+---
 
-New demos are added within 24–48 hours of match completion. The pipeline runs continuously across dedicated VPS infrastructure.
+## Update Policy
 
-## Data Source
+New demos are added **within 24–48 hours** after match completion. The ingestion pipeline runs 24/7.
 
-Demos sourced from [HLTV.org](https://www.hltv.org) — the official repository for professional CS2 match data. HLTV is the authoritative source for all competitive CS2/CS:GO results and replays.
