-# CounterQuant-CS2-Demos
+# CounterQuant CS2 Demos
 
-**Official CS2 Tier 1 match demo files.**
+Raw CS2 (Counter-Strike 2) demo files (.dem) collected from HLTV — the authoritative competitive CS2 demo repository.
 
-Raw `.dem` files extracted from HLTV demo archives.
-Organized as `data/{year}/{match_id}/{map}.dem`.
+**Curated and maintained by [Eimantas Kulbe](https://github.com/redrum88) 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.
+
+**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.
+
+## Coverage
+
+| Tier | Description | Years | Status |
+|------|-------------|-------|--------|
+| T1 | Major/S-tier events (top 20 world teams) | 2024–present | Active — daily updates |
+| T2 | A-tier events (top 50 teams) | 2024–present | Active — daily updates |
+| T3 | B-tier / regional events | 2024–present | In progress |
+| Historical | CS:GO T1/T2 (pre-2024) | 2012–2023 | Planned |
+
+## File Structure
+
+```
+data/
+  {year}/
+    tier{N}/
+      {match_id}/
+        {map_name}.dem
+```
+
+Example:
+```
+data/2024/tier1/2378549/astralis-vs-natus-vincere-mirage.dem
+data/2025/tier2/2401337/team-vitality-vs-g2-inferno.dem
+```
 
 ## Usage
-Use [demoparser2](https://github.com/LaihoE/demoparser2) or [awpy](https://github.com/pnxenopoulos/awpy) to parse.
+
+### Parse with demoparser2 (Python)
+
+```python
+from demoparser2 import DemoParser
+
+parser = DemoParser("data/2024/tier1/2378549/astralis-vs-natus-vincere.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"])
+```
+
+### Download via huggingface_hub
+
+```python
+from huggingface_hub import snapshot_download
+
+# Download all 2024 T1 demos
+path = snapshot_download(
+    repo_id="KEDevO/CounterQuant-CS2-Demos",
+    repo_type="dataset",
+    allow_patterns="data/2024/tier1/**",
+    local_dir="./demos",
+)
+```
+
+### Stream individual files
+
+```python
+from huggingface_hub import hf_hub_download
+
+dem = hf_hub_download(
+    repo_id="KEDevO/CounterQuant-CS2-Demos",
+    repo_type="dataset",
+    filename="data/2024/tier1/2378549/match.dem",
+)
+```
+
+## What You Can Do With These Demos
+
+- **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
+
+## Update Schedule
+
+New demos are added within 24–48 hours of match completion. The pipeline runs continuously across dedicated VPS infrastructure.
+
+## Data Source
+
+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.
