 ## Open database
 
-    #include <sqlitelib.h>
-    using namespace sqlitelib;
-    auto db = Sqlite("./test.db");
+```cpp
+#include <sqlitelib.h>
+using namespace sqlitelib;
+auto db = Sqlite("./test.db");
+```
 
 ## Create table
 
-    db.execute(R"(
-      CREATE TABLE IF NOT EXISTS people (
-        id INTEGER PRIMARY KEY AUTOINCREMENT,
-        name TEXT,
-        age INTEGER,
-        data BLOB
-      )
-    )");
+```cpp
+db.execute(R"(
+  CREATE TABLE IF NOT EXISTS people (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    name TEXT,
+    age INTEGER,
+    data BLOB
+  )
+)");
+```
 
 ## Drop table
 
-    db.execute("DROP TABLE IF EXISTS people");
+```cpp
+db.execute("DROP TABLE IF EXISTS people");
+```
 
 ## Insert records
 
-    auto stmt = db.prepare("INSERT INTO people (name, age, data) VALUES (?, ?, ?)");
-    stmt.execute("john", 10, vector<char>({ 'A', 'B', 'C', 'D' }));
-    stmt.execute("paul", 20, vector<char>({ 'E', 'B', 'G', 'H' }));
-    stmt.execute("mark", 15, vector<char>({ 'I', 'J', 'K', 'L' }));
-    stmt.execute("luke", 25, vector<char>({ 'M', 'N', 'O', 'P' }));
+```cpp
+auto stmt = db.prepare("INSERT INTO people (name, age, data) VALUES (?, ?, ?)");
+stmt.execute("john", 10, vector<char>({ 'A', 'B', 'C', 'D' }));
+stmt.execute("paul", 20, vector<char>({ 'E', 'B', 'G', 'H' }));
+stmt.execute("mark", 15, vector<char>({ 'I', 'J', 'K', 'L' }));
+stmt.execute("luke", 25, vector<char>({ 'M', 'N', 'O', 'P' }));
+```
 
 ## Select a record (single colum)
 
-    auto val = db.execute_value<int>("SELECT age FROM people WHERE name='john'");
-    val; // 10
+```cpp
+auto val = db.execute_value<int>("SELECT age FROM people WHERE name='john'");
+val; // 10
+```
 
 ## Select records (multiple columns)
 
-    auto rows = db.execute<int, std::string>("SELECT age, name FROM people");
-    rows.size(); // 4
+```cpp
+auto rows = db.execute<int, std::string>("SELECT age, name FROM people");
+rows.size(); // 4
 
-    auto [age, name] = rows[3]; // age: 25, name: luke
+auto [age, name] = rows[3]; // age: 25, name: luke
+```
 
 ## Bind #1
 
-    auto stmt = db.prepare<std::string>("SELECT name FROM people WHERE age > ?");
+```cpp
+auto stmt = db.prepare<std::string>("SELECT name FROM people WHERE age > ?");
 
-    auto rows = stmt.execute(10);
-    rows.size(); // 3
-    rows[0];     // paul
+auto rows = stmt.execute(10);
+rows.size(); // 3
+rows[0];     // paul
 
-    auto rows = stmt.bind(10).execute();
-    rows.size(); // 3
-    rows[0];     // paul
+auto rows = stmt.bind(10).execute();
+rows.size(); // 3
+rows[0];     // paul
+```
 
 ## Bind #2
 
-    auto val = db.execute_value<int>("SELECT id FROM people WHERE name=? AND age=?", "john", 10);
-    val; // 1
+```cpp
+auto val = db.execute_value<int>("SELECT id FROM people WHERE name=? AND age=?", "john", 10);
+val; // 1
+```
 
 ## Cursor (multiple columns)
 
-    auto stmt = db.prepare<std::string, int>("SELECT name, age FROM people");
+```cpp
+auto stmt = db.prepare<std::string, int>("SELECT name, age FROM people");
 
-    auto cursor = stmt.execute_cursor();
-    for (auto it = cursor.begin(); it != cursor.end(); ++it) {
-      get<0>(*it);
-      get<1>(*it);
-      ++it;
-    }
+auto cursor = stmt.execute_cursor();
+for (auto it = cursor.begin(); it != cursor.end(); ++it) {
+  get<0>(*it);
+  get<1>(*it);
+  ++it;
+}
 
-    // With C++17 structured binding
-    for (const auto& [name, age] : stmt.execute_cursor()) {
-      ;
-    }
+// With C++17 structured binding
+for (const auto& [name, age] : stmt.execute_cursor()) {
+  ;
+}
+```
 
 ## Cursor (single column)
 
-    auto stmt = db.prepare<std::string>("SELECT name FROM people");
+```cpp
+auto stmt = db.prepare<std::string>("SELECT name FROM people");
 
-    for (const auto& x: stmt.execute_cursor()) {
-      ;
-    }
+for (const auto& x: stmt.execute_cursor()) {
+  ;
+}
+```
 
 ## Count
 
-    auto val = db.execute_value<int>("SELECT COUNT(*) FROM people");
-    val; // 4
+```cpp
+auto val = db.execute_value<int>("SELECT COUNT(*) FROM people");
+val; // 4
+```
 
 ## Flat API
 
-    for (const auto& [name, age] :
-         db.execute_cursor<string, int>("SELECT name, age FROM people")) {
-      ;
-    }
+```cpp
+for (const auto& [name, age] :
+     db.execute_cursor<string, int>("SELECT name, age FROM people")) {
+  ;
+}
 
-    for (const auto& x: db.execute_cursor<std::string>("SELECT name FROM people")) {
-      ;
-    }
+for (const auto& x: db.execute_cursor<std::string>("SELECT name FROM people")) {
+  ;
+}
+```
