-To export table data to a CSV file, use the sequence of SQLite commands below:
-Ex: exporting Table nlbse_tool_competition_data_by_issue to a CSV file.
-```
-sqlite3 skillscope_data.db 
-.headers on
-.mode csv
-.output output.csv
-SELECT * FROM nlbse_tool_competition_data_by_issue;
-.quit
-```
-Important: CSV file will have zero bytes until you use the ```.quit``` statement !
 
+# NLBSE 2026 Skill Competition Dataset
 
-Alternatively, you can simply call sqlite3 and check the available tables.
-The statement ```.table``` will list the available tables.
 
-```
-sqlite3
-.tables
-.open skillscope_data.db
-```
+Refer to [the NLBSE 2026 Competition Announcement](https://nlbse2026.github.io/tools/#:~:text=the%20workshop%20proceedings.-,Skill%20Classification%20Competition,-Competition%20Overview) for more information about the NLBSE 2026 Skill Competition and this included dataset.

+> Note, the previous version of this dataset contained a CSV file, which was simply an export of the `nlbse_tool_competition_data_by_issue` table of the SQLite file.
+> However, it was reported that there were errors in the CSV file as several cells from the table contained newlines, quotes, and other special characters.
+> Therefore, the CSV file was removed. It is now recommended to use SQLite queries against the SQLite file directly.
