+This repository contains general build scripts and pipelines for all languages that I incorporate in my projects. The goal is to provide an easy retrieval and update system for the project. Each script will be a shell script containing the following template:
+```bash
+    #Short description about what I do
+    #Language[Folder]
+    # #The script's code goes in here.
+    # rm -Rf out/*
+    # javac -Xlint:unchecked -cp ${PROJECT_DIR}/.. -d ${OUT_DIR} ${PROJECT_DIR}/*.java
+    # printf "\n\n\nRunning Program...\n\n"
+    # cd $OUT_DIR
+    # java ${MAIN_CLASS} "$@"
+    # ../scripts/clean.sh
+    
+```
+Each language will be in the following structure:
+```
+    -<Language>
+    --<scripts>
+    ---[script files.sh]
+```
+
+The `sig` script will display by default any scripts in the `scripts` folder, therefore when creating a project, copy over the scripts folder of the desired language into your project then the `sig` script handles the rest appropriately. If your project requires multiple languages and build setups, then you can use the `sig2` command, which has an additional parameter to specify the language when running it. When setting up a multi-language setup, you'll just copy the entire folder to include the programming language itself. So a multi-language project structure may look something like this:
+```
+    -C
+    --scripts
+    ---build.sh
+    ---clean.sh
+    ---make.sh
+    -Java
+    --scripts
+    ---build.sh
+    ---clean.sh
+    ---jar.sh
+```
