+## How to install `CLI-compdev`
+
+Download CLI-compdev release from [here](), unzip the getted archive and follow the guide for your OS.
+
+### On `MacOS`
+
+Before starting, you can delete `windows` and `config/win_makefile` folders.
+
+#### 1. Setting up `config` folder 
+Move `config` folder wherever you want on you MacOS. 
+
+I suggest you to create a new directory, e.g. `~/Documents/compdev`, where you can easily put the `config` folder. 
+
+Be sure you remember where you put this directory because you are going to use its path.
+
+#### 2. Setting up `compdev.sh` file
+Open `unix` folder and edit `compdev.sh` file. You have to replace `config_path` constant at the beginning of the file with the path to `config` folder.
+
+```sh
+#!/bin/bash
+
+program=compdev
+current_dir=.
+
+# path to program config folder
+config_path=path/to/config/folder   # Edit this, e.g.
+                                    # config_path=~/Documents/compdev/config
+
+[...]
+```
+
+#### 3. Move `compdev.sh` to the correct location
+Open Terminal application, navigate to the folder where you have `compdev.sh` and move the file into `/usr/local/bin` system directory with the command below.
+
+```bash
+sudo mv ./compdev.sh /usr/local/bin/COMPDEV
+```
+
+As `/usr/local/bin` directory is owned by user root, you must be an admin and use `sudo` to move files there.
+
+#### 4. Set owner and permissions
+The script should be owned by and writable for root, but readable and executable for everyone. The two commands below ensure this:
+
+```bash
+sudo chown root: /usr/local/bin/COMPDEV
+sudo chmod 755 /usr/local/bin/COMPDEV
+```
+
+### On `Windows`
+
+Be sure you have [`WSL`]() installed on your PC before starting install `compdev`.
+
+Before starting, you can delete `unix` folder and `config/Makefile` file.
+
+#### 1. Setting up `config` folder
+Move `config` folder wherever you want on your Windows. 
+
+I suggest you to create a new directory, e.g. `C:\Users\Andrea\Documents\compdev`, where you can easily put the `config` folder. 
+
+Be sure you remember where you put this directory because you are going to use its path.
+
+#### 2. Setting up `compdev.sh` file
+Open `windows` folder and edit `compdev.sh` file. You have to replace `config_path` constant at the beginning of the file with the path to `config` folder.
+
+```sh
+#!/bin/bash
+
+program=compdev
+current_dir=.
+
+# path to program config folder
+config_path=path/to/config/folder/in/wsl    # Edit this, e.g.
+                                            # config_path=/mnt/c/Users/Andrea/Documents/compdev
+
+[...]
+```
+
+#### 3. Move `compdev.sh` and `compdev.bat` to the correct location
+Move `compdev.sh` and `compdev.bat` files into `C:\Windows\System32` folder.
+
+## Get started with `compdev`
+
+You can use `compdev` to create a project already formatted and possibly templated for the development of your own compiler.
+
+For now, you can use it just with `jflex` and `java_cup`, because just their module are loaded into `config/module` folder and, morover, templated and non-templated initialization is based on them.
+
+The complete list of command at the moment available is shown below.
+
+### `init`
+
+You can use `compdev init` to initialize your project.
+
+```bash
+$ compdev init <project_name> [--template]
+```
+
+You should type the name of your new project instead of `<project_name>`, but you can also type `.` instead of `<project_name>` to initialize your project in the current directory where you are running this command.
+
+The default initialization, without `--template` option, create the following project structure:
+
+```
+|--- /<project_name>
+     |--- /build
+     |--- /modules
+     |--- /source
+     |    |--- /scanner.jflex
+     |    |--- /parser.cup
+     |
+     |--- /Makefile
+```
+
+The `--template` option is not mandatory, but, if you use it, the project is initialized with `jflex` and `java_cup` preloaded into `modules` folder. In addition, `scanner.flex`, `parser.cup` and `Makefile` are templated on the same files you can find within `config` folder. Here the `--template` option project structure:
+
+```
+|--- /<project_name>
+     |--- /build
+     |--- /modules
+     |    |--- /java_cup
+     |    |--- /jflex
+     |
+     |--- /source
+     |    |--- /scanner.jflex (Templated)
+     |    |--- /parser.cup (Templated)
+     |
+     |--- /Makefile (Templated)
+```
+
+### `add`
+
+If you have already initialized your project, maybe without `--template` option, and you want to add a module, you can use the `compdev add` command.
+
+```bash
+$ compdev add <module_name>
+```
+
+At the moment, just `jflex` and `java_cup` are defined as modules and just them are within the `config` folder. So you can use just their name instead of `<module_name>`.
+
+### `help`
+
+For info about commands available, you can run `compdev help`.
+
+```bash
+$ compdev help
+```
+
+## Community collaboration
+
+I would be very happy if you expanded this project.
+
+You can expand and edit `compdev` with whatever you want. You can add new modules and new templates by means editing source code and you can also suggest optimizations or prettier code.
+
+In addition, I also suggest you to watch [issues]().
+
+I know this program is not perfect but I think it can be a good starting point, so you are welcome!
+
+## Changelog
+
+Here you can check changes between software releases.
+
+### `v0.0.1`
+- Release of `compdev` for Unix-like OS and Windows. 
+- Just `jflex` and `java_cup` modules support available.
