 # UrlsWorker
 
-The Worker's Application, requests assignments from the [Controller](https://code-repo.d4science.org/lsmyrnaios/UrlsController) and processes them, downloading the available full-texts.<br>
+The Worker's Application, requests assignments from the [Controller](https://code-repo.d4science.org/lsmyrnaios/UrlsController) and processes them with the help of the [__PublicationsRetriever__](https://github.com/LSmyrnaios/PublicationsRetriever) software and downloads the available full-texts.<br>
 Then, it posts the results to the Controller, which in turn, requests from the Worker, the full-texts which are not already found by other workers, in batches.<br>
 The Worker responds by compressing and sending the requested files, in each batch.<br>
 <br>
 We use Facebook's [**Zstandard**](https://facebook.github.io/zstd/) compression algorithm, which brings very big benefits in compression rate and speed.  
 <br>
-To install and run the application:
-- Run ```git clone``` and then ```cd UrlsWorker```.
-- [Optional] Create the file ```inputData.txt``` , which contains just one line with the ___workerId___, the ___maxAssignmentsLimitPerBatch___, the ___maxAssignmentsBatchesToHandleBeforeRestart___, the ___controller's base api-url___ and the ___shutdownOrCancelCode___, all seperated by a _comma_ "```,```" .<br>
-    For example: ```worker_1,1000,0,http://IP:PORT/api/,stopOrCancelCode```.<br>
-    The ___shutdownOrCancelCode___ is kind of an "auth-code", when receiving "__shutdown__" and "__cancel-shutdown__" requests.
-- Execute the ```installAndRun.sh``` script.<br>
-    In case the above file (_inputData.txt_) does not exist, the script will request the required data from the user, and then it will create the _inputData.txt_ file.<br>
 <br>
 
-Notes:
-- If the "maxAssignmentsBatchesToHandleBeforeRestart" is zero or negative, then an infinite number of assignments-batches will be handled.<br>
-- The above script, installs the [PublicationsRetriever](https://github.com/LSmyrnaios/PublicationsRetriever), as a library and then compiles and runs the whole Application.<br>
-- If you want to just run the app, then run the script with the argument "1": ```./installAndRun.sh 1```.<br>
+**To install and run the application**:
+- Run ```git clone``` and then ```cd UrlsWorker```.
+- Set the preferable values inside the [__application.properties__](https://code-repo.d4science.org/lsmyrnaios/UrlsWorker/src/branch/master/src/main/resources/application.properties) file.
+- Execute the ```installAndRun.sh``` script.<br>
+<br>
+
+**Notes**:
+- The above script, installs the [PublicationsRetriever](https://github.com/LSmyrnaios/PublicationsRetriever) software, as a library and then compiles and runs the whole Application.<br>
+- If you want to just run the app, then run the script with the argument "1": ```./installAndRun.sh 1```. In this scenario, apart from the SpringBoot-app not re-building,
+the [PublicationsRetriever](https://github.com/LSmyrnaios/PublicationsRetriever) software, will not be re-installed as well.<br>
+- If you want to avoid re-installing the [PublicationsRetriever](https://github.com/LSmyrnaios/PublicationsRetriever) software, i.e. when using a development (non-published) version
+or when nothing has changed and wanting to avoid the time-overhead, run the script with the argument "0", followed by the argument "1": ```./installAndRun.sh 0 1```.<br>
