+# SQL Murder Mystery
 
+There's been a Murder in SQL City! The SQL Murder Mystery is designed to be both a self-directed lesson to learn SQL concepts and commands and a fun game for experienced SQL users to solve an intriguing crime.
+
+## Getting Started
+* **For experienced SQL users**: read the prompt_experienced file, then download the sql-murder-mystery.db file and use a SQL environment of your choice to solve the mystery. You can use the cheatsheet to refresh your memory on SQL. Try to complete the activity all within your SQL environment (without writing down notes)!
+
+* **For SQL beginners**: start with the cheatsheet to learn the basics of SQL, read the prompt_beginner file, then download the sql-murder-mystery.db file and load it in a SQL environment of your choice (we recommend the [SQLiteStudio](https://sqlitestudio.pl/index.rvt "SQLiteStudio")). If you get stuck at any point, feel free to refer back to the cheatsheet.
+
+## Checking the Solution
+Write the following queries in your SQL environment to check whether you've found the right murderer:
+
+`INSERT INTO solution VALUES (1, "Insert the name of the person you found here");`
+
+`SELECT value FROM solution;`
