 ### Task
 Task is an atomic piece of work executed by recodex-worker. There are two basic types of tasks:
-- **Execute external process** (optionally inside Isolate). Linux default will be mandatory in Isolate, this option is here because of Windows.
+- **Execute external process** (optionally inside Isolate). Linux default is mandatory usage of isolate, this option is here because of Windows, where is currently no sandbox available.
 - **Perform internal operation**. External processes are meant for compilation, testing, or execution of external judges. Internal operations comprise commands, which are typically related to file/directory maintenance and other evaluation management stuff. Few important examples:
    - Create/delete/move/rename file/directory
    - (un)zip/tar/gzip/bzip file(s)

 Even though the internal operations may be handled by external executables (`mv`, `tar`, `pkzip`, `wget`, ...), it might be better to keep them inside the recodex-worker as it would simplify these operations and their portability among platforms. Furthermore, it is quite easy to implement them using common libraries (e.g., _zlib_, _curl_).
 
 **External Tasks**
-These tasks are typically executed in isolate (with given parameters) and the recodex-worker waits until they finish. The exit code determines, whether the task succeeded (0) or failed (anything else). A task may be marked as essential; in such case, failure will immediately cause termination of the whole job.

 - **stdout** and **stderr** - can be individually redirected to a file or discarded. If this output options are specified, than it is possible to upload output files with results by copying them in result directory.
 - **limits** - task have time and memory limits; if these limits are exceeded, the task also fails.

 ### Directories and Files
 For each job execution unique directory structure is created. Job is not restricted to specified directories (tasks can do whatever is allowed on system), but it is advised to use them inside job. In recodex-worker configuration one can specify worker default directory, this is base of every file which is produced by recodex-worker.
