 # Symbolic Observation Graph-Based Generation of Test Paths
 
-`sog-test-paths` generates the observable paths from a Petri net model. It also
+`sogMBT` generates the observable paths from a Petri net model. It also
 generates the abstract paths.
 
 ## Requirements
 
-- A C++ compiler (`gcc >= 9.3.0`).
+- `gcc >= 9.3.0`.
+- `cmake`
 
-## Compilation
+## Build
 
-The tool can be compiled as follow:
+The tool can be compiled as follows:
 
-- First, run the `make` command inside the directory `buddy22` in order to build
-  the library used to manipulate Binary Decision Diagrams (BDD).
-
-- Second, run `make` in the `parser` directory in order to build the library
-  used to parse Petri net models from `net` files.
-
-- Third, run the `make` command in the root directory to generate the executable
-  file `sog-test-paths`.
+```bash
+mkdir build && cd build
+cmake ..
+make

-
-The following commands are available:
-
-- To generate the reachability graph: use the option `-r <filename.net>`.
-- To generate test paths covering the given observable transitions `t1,t2,...,tn`, use the option `-o <filename.net> <output_file>`.
-- To generate test paths using structural analysis, use the option `-a <filename.net>`
-- To generate the complete SOG corresponding to observable transitions, use the option `-c <filename.net>`
