 Occlum is a *memory-safe*, *multi-process* library OS (LibOS) for [Intel SGX](https://software.intel.com/en-us/sgx). As a LibOS, it enables *unmodified* applications to run on SGX, thus protecting the confidentiality and integrity of user workloads transparently. 
 
 Compared to existing LibOSes for SGX, Occlum has following salient features:
 
-  * **Efficient multitasking.** The LibOS has a complete and efficient multi-process support, including fast process creation, low-cost IPC, code sharing (e.g., shared libraries) and data sharing (e.g., encrypted file systems).
+  * **Efficient multitasking.** The LibOS has a complete and efficient multi-process support, including fast process creation, low-cost IPC, shared OS services (e.g., encrypted file systems).
   * **Fault isolation.** The crash of one user process cannot crash the LibOS or other user processes, which is good for security and robustness.
   * **Memory safety.** The LibOS itself is written in [Rust](https://www.rust-lang.org/), a memory-safe programming language, thus free from low-level, memory bugs;

 While Occlum was originally designed by and incubated inside Intel, it is NOT an official Intel product.
