+### Build test app
+
+Please install first: g++ cmake pkg-config
+
+Build:
+``` bash
+$ ./build_simple.sh
+```
+
+Run help:
+``` bash
+$ ./wsjcpp-obj-tree --help
+
+  Usage: ./wsjcpp-obj-tree [OPTIONS]
+  Options: 
+    --help | -h         help
+  Input or source data can be (only one): 
+    --input <file> | -i <file>     input binary file with tree
+    --random N | -r N              generate random data (more than 0 and less than 1000000)
+    --example | -e                 hardcoded example
+  Output data can be (only one): 
+    --output <file> | -o <file>    output binary file for tree
+    --print | -p                   output binary file for tree
+
+  Command examples:
+    Print example of the tree: 
+        './wsjcpp-obj-tree -e -p'
+    Print random tree: 
+        './wsjcpp-obj-tree -r 20 -p'
+    Output example of the tree to file: 
+        './wsjcpp-obj-tree -e -o some.wsjcpp-obj-tree'
+    Input from file and output to file: 
+        './wsjcpp-obj-tree -i some.wsjcpp-obj-tree -o some2.wsjcpp-obj-tree'
+```
