+# License
+Test programs of this directory are provided under BSD license (see associated
+LICENSE file).
+
+# Compilation
+After installation, you can use pkg-config to compile these tests.
+For example, to compile random-test-server run:
+
+gcc random-test-server.c -o random-test-server `pkg-config --libs --cflags libmodbus`
+
+- `random-test-server` is necessary to launch a server before running
+random-test-client. By default, it receives and replies to Modbus query on the
+localhost and port 1502.
+
+- `random-test-client` sends many different queries to a large range of
+addresses and values to test the communication between the client and the
+server.
+
+- `unit-test-server` and `unit-test-client` run a full unit test suite. These
+programs are essential to test the Modbus protocol implementation and libmodbus
+behavior.
+
+- `bandwidth-server-one`, `bandwidth-server-many-up` and `bandwidth-client`
+ return very useful information about the performance of transfer rate between
+ the server and the client. `bandwidth-server-one` can only handles one
+ connection at once with a client whereas `bandwidth-server-many-up` opens a
+ connection for each new clients (with a limit).
