-**Warning:** This is a dev version, might be unstable or have errors.
+**Warning:** This is a dev version - it might be unstable or have errors, because it has not been tested properly. Feel free to test it yourself and report errors.
 
 ## Instalation
-
 ```
 npm install -g https://github.com/tao24/gcg.git#dev
 ```
 
-## Local building and testing
-
-1. Clone repository:
+## Usage instruction
 
+### Directory management
 ```
-git clone -b dev https://github.com/tao24/gcg.git gcg-dev
-cd gcg-dev
+gcg init <task-name> [--overwrite] [--input-only]
 ```
 
-2. Intall, build and run project locally:
+Initializes directory with template `.cpp` file and tests (you should start copying tests to clipboard).
 
-```
-npm install
-npm run build
-npm start <params>
-```
+Flag `--input-only` makes it so it creates only `*.in` files, omitting `*.out` files. Make sure to create `[task-name]_out.exe` validator file working as specified below.
 
-3. (optional) Before publishing (pushing to repository), remember to build in production mode first:
+### Testing
 
 ```
-npm run build:prod
+gcg run <task-name> [-f <folder-name>] [-t <test-name>] [--no-compile]
 ```
 
+Runs specified task on its tests (tests in folder `tests` which begin with `<task-name>` and all test in folder `tests/<task-name>`). 
+#### Available options:
+- `-f, --folder <folder-name>` runs program on all tests in specified folder,
+- `-t, --test <test-name>` runs program only on specified test (but it must be in either `tests` folder, in `tests/<program-name>` or in folder specified by `-f <folder-name>`),
+- `--no-compile` turns off compiling program before testing.
 
+If no corresponding `.out` or `.ans` files are found, then it tries to use `<task-name>_out[.exe]` executable to validate program. Validator should work as follows:
 
-## Usage instruction
+1. read from stdin test specification (`<test-name>.in` file)
+2. read from stdin your programs' output
+3. validate output
+4. if result is ok, return with no result. If not, it should print non-empty string on standard output (it will be displayed in console during testing). 
+
+**Note**: Validator runs ```g++ -std=c++17 <task-name>.cpp -o <task-name>```. Make sure you have a c++ compiler.
+
+
+## Local building and testing
+
+1. Clone repository:
 
-### Directory management
 ```
-gcg init [task-name] [--overwrite]
+git clone -b dev https://github.com/tao24/gcg.git gcg-dev
+cd gcg-dev
 ```
 
-Initializes directory with template ```.cpp``` files and tests (you should start copying tests to clipboard). If [task-name] is specified, then it only initializes this task.
-
-### Testing
+2. To install and run project locally:
 
 ```
-gcg run <task-name> [--no-compile]
+npm install
+npm start -- <params>
 ```
 
-Runs specified task on its tests (any test that begins with ```<task-name>```). Flag ```--no-compile``` turns off compiling.
+3. (optional) To install CLI from local folder:
+
+```
+npm run build
+npm install -g
+```
 
-**Note**: Validator runs ```g++ -std=c++17 <task-name>.cpp -o <task-name>```. Make sure it works.
