+# Coder Judge
+
+## About project
+Coder Judge is an open-source platfrom written in Java and Python to compile and run code submissions against test-cases. It uses RabbitMQ to fetch pending jobs, compiles them and then runs agains test cases.
+After judging, one of these verdics are possible for the code.
+- `COMPILE-ERROR`
+- `ACCEPT`
+- `WRONG-ANSWER`
+- `RUNTIME-ERROR`
+- `TIME-LIMIT`
+- `MEMORY-LIMIT`
+
+Currently, we support `C++` and `Python` as the submission languages. You can add other languages by simply adding compiler in `app/other/compile.py` and modifying the runner script in `app/other/run.py`.
+
+## Project Setup
+
+You need `java` and `gradle` on your system to run this project.
+### Environment file pattern
+The `.env` file must be placed in the root directory following the pattern described below.
+```
+DB_URL=                                # database host address (including port)
+DB_USER=                             # database username
+DB_PASSWD=                       # database password
+
+QUEUE_HOST=                     # queue host address (including port)
+QUEUE_USER=                      # queue username 
+QUEUE_PASSWD=                # queue password
+SUBMISSION_QUEUE_NAME=     # queue name for submissions
+RESULT_QUEUE_NAME=               # queue name for results
+
+FILE_PATH=                           # root filesystem path
+```
+
+### Setup envirounment variables
+You need to set-up every variable on your `.env` file to your current envirounment. This can simply done with Docker, or on `bash` with:
+```
+$ export $(grep -v '^#' .env | xargs)
+```
+### Run the project
+```
+./gradlew run
+```
