+#### Using MinGW+MSYS to create DLL
+
+DLL can be created using MinGW+MSYS with the "make liblz4" command.
+This command creates "liblz4.dll" and the import library "liblz4.dll.a".
+To compile a project the import library has to be added to linking options.
+It means that if a project that uses LZ4 consists of a single test-dll.c 
+file it should be compiled with "liblz4.dll.a". For example:
+```
+    gcc $CFLAGS test-dll.c -o test-dll liblz4.dll.a
+```
