 - **Community interests** and shifts in developer focus over 12 years
 - **Viral repository dynamics** and sustained popularity patterns
 
+**Key Statistics:**
+- 📊 **423,098** trending repository entries
+- 🗂️ **14,500** unique repositories
+- 📅 **128 months** of coverage (2013-08 to 2025-11)

 ## 🔧 Dataset Configurations
 
 This dataset has **two configurations** defined in the YAML header:
@@ -100,10 +107,278 @@ This rewards both **consistency** (frequent appearances) and **position** (highe
 **Snapshots:** 17,127 successfully scraped from 19,064 available
 **Retry Logic:** Up to 15 retries with exponential backoff
 
+## ⚠️ Known Limitations
+
+### 1. **Missing Star/Fork Data (Pre-2020)**
+- **100% of 2013-2019 entries** lack star/fork counts
+- Only **67.8% of dataset** has popularity metrics
+- **Impact:** Cannot compare absolute popularity for historical projects
+
+### 2. **Uneven Temporal Distribution**
+- Snapshot frequency: **1 to 31 per month** (31x variance)
+- 2019-2020 heavily over-represented
+- **Impact:** Monthly scores favor periods with more snapshots
+
+### 3. **Star Count Timing Inconsistency**
+- Star counts are "maximum ever recorded" across all snapshots
+- A 2015 project's stars might be from 2025 scraping
+- **Impact:** Can't fairly compare popularity across eras

+## 📈 Data Quality by Era
+
+| Era | Quality | Star Data | Snapshot Density | Grade |
+|-----|---------|-----------|------------------|-------|
+| **2013-2019** | Limited | ❌ 0% | Low-Medium | **C+** |

+
+## 💡 Usage Examples
+
+### Load with Hugging Face Datasets (Recommended)
+
+```python
+from datasets import load_dataset
+
+# Load complete daily dataset (423,098 entries)
+ds_full = load_dataset('ronantakizawa/github-top-projects', 'full')
+df_full = ds_full['train'].to_pandas()
+
+# Load monthly top 25 dataset (3,200 entries)
+ds_monthly = load_dataset('ronantakizawa/github-top-projects', 'monthly')
+df_monthly = ds_monthly['train'].to_pandas()
+
+# Filter to 2020+ (with star data)
+df_recent = df_full[df_full['date'] >= '2020-01-01']
+
+# Get November 2025 top 10
+nov_2025 = df_monthly[df_monthly['month'] == '2025-11'].head(10)
+print(nov_2025[['rank', 'repository', 'star_count', 'ranking_appearances']])
+```
+
+### Time Series Analysis
+
+```python
+import pandas as pd
+import matplotlib.pyplot as plt
+from datasets import load_dataset
+
+ds = load_dataset('ronantakizawa/github-top-projects', 'full')
+df = ds['train'].to_pandas()
+df['date'] = pd.to_datetime(df['date'])
+
+# Analyze a specific project over time
+project = 'microsoft/vscode'
+project_df = df[(df['repo_owner'] == 'microsoft') & (df['name'] == 'vscode')]
+
+# Plot trending frequency over time
+monthly_counts = project_df.groupby(project_df['date'].dt.to_period('M')).size()
+monthly_counts.plot(title=f'{project} Trending Frequency')
+plt.ylabel('Days in Trending')
