+### How to add crates
+
+Create a file "addons/sourcemod/configs/respawn-unlocker.txt" with the following structure:
+
+```
+"Crates"
+{
+    "dod_gan_games" // Map name
+    {
+        "1" // Crate's number
+        {
+            "position_x"    "320"  // Position of the center
+            "position_y"    "-128" // Position of the center
+            "position_z"    "64"   // Position of the bottom
+        }
+
+        "2"
+        {
+            "position_x"    "320"
+            "position_y"    "-108"
+            "position_z"    "104"
+        }
+
+        "3"
+        {
+            "position_x"    "2300"
+            "position_y"    "-128"
+            "position_z"    "64"
+        }
+
+        "4"
+        {
+            "position_x"    "2300"
+            "position_y"    "-108"
+            "position_z"    "104"
+        }
+    }
+}
+```
+
+This is how crates "3" and "4" will look like in the game:
