Instead of cd ../../, specify the path from the folder created from "git clone "
If get code by command "https://github.com/facebookexperimental/S1APTester.git" S1APTester is folder created. You can specify path from S1APTester

When we compile S1ap tester code within magma_test VM, generated library libtfw.so is copied to path "/home/vagrant/s1ap-tester/bin".
Even I didn't locate libtfw.so file in path /usr/lib/
So in what context libtfw.so is copied to /usr/lib/?

In case of using S1APTester with normal magma setup, the steps of copying the libtfw.so file to /home/vagrant/s1ap-tester/bin/ is part of VM provisioning and the python scripts are importing directly from this path.

As of now, the stub binary "testCntrlr" is trying to search the libtfw.so file in default lib folders as the path is not specified with the binary. This is why we need to copy the .so file in /usr/lib/ folder.

On successful compilation, the “libtfw.so” library gets generated under
TestCntlrApp/lib folder.
TestCntlrApp/lib folder which is copied to ``/usr/lib``.

which is copied to => which needs to be / should be copied to
The copying of .so file does not happen automatically as part of compilation and needs to be done separately as shown in steps.

@VinashakAnkitAman Referring line number 56, libtfw.so is getting copied to /usr/lib
So sentence in line number 60 looks to be fine

This statement is not needed here in the steps: cd ../bin/

```
Upon successful compilation, an executable binary ``testCntrlr`` is created in the ``bin`` directory.


## Configure eNodeB Parameters
Example eNodeB configuration file can be found in ``TestCntlrApp/cfg/nbAppCfg.txt``,

In this file you will need to put in the parameters for your EPC, such as Cell ID, TAC, MCC/MNC, IP Addresses, etc.

## Configure UE Parameters
Example UE parameter file can be found in ``TestCntlrApp/cfg/ueCfg.txt``,

In this file you will need to put in the crypto parameters for your HSS, such as OP key and K Keys.

Each IMSI you want to test will need to be defined in ``TestCntlrApp/cfg/imsi.txt``

## Running S1AP Test
After configuring your eNodeB & UE parameters, you can run the ``TestCntlrStub`` with one of the example test cases,
```
$ cd TestCntlrStub/bin
$ sudo ./testCntrlr -f testCaseList_1.txt
```

Log messages will be shown on screen and in the text file ``log`` created in the same directory.
