+## About
+In the framework of this project, an automatic profile information collection system using BOLT technology was introduced. When using profile optimizations, Clang compiler performance increases up to 30%, after the profile has been collected, it should be passed to the compiler for re-optimization, but in many cases recompilation is't possible.
+BOLT is the technology that solves this problem. BOLT allows for significant acceleration without recompiling.
+
+Perfd is implemented as a Python script. It is registered in the system as a service using systemd. Profile collection uses Linux perf system utility.The database is sqlite.
+
+## Documentation
+
+### BOLT:
+- **`BOLT`** - is a post-link optimizer developed to speed up large applications. It achieves the improvements by optimizing application's code layout based on execution profile gathered by sampling profiler, such as Linux perf tool.
+
+### SQL30:
+- **`SQL30`** - is a zero weight ORM(Object–relational mapping) for sqlite3 in Python.
+- **`ORM(Object–relational mapping)`** - in computer science is a programming technique for converting data between type systems using object-oriented programming languages. This creates, in effect, a "virtual object database" that can be used from within the programming language.
+### Systemd:
+- **`Systemd`** - это менеджер демонов в Linux. Этот демон позволяет управлять запуском сервисов и обеспечивает такие функции, как мониторинг и логирование.
+
+## Installation
+### BOLT:
+ > ` git clone https://github.com/facebookincubator/BOLT llvm-bolt`
+ >`mkdir build`
+ > `cd build`
+ > `cmake -G Ninja ../llvm-bolt/llvm -DLLVM_TARGETS_TO_BUILD="X86;AArch64" -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_ASSERTIONS=ON -DLLVM_ENABLE_PROJECTS="clang;lld;bolt"`
+ > `ninja`
+
+### SQL30:
+- **`pip install sql30`**
+
+### Systemd:
+ > `apt-get update -y`
+ > `apt-get install -y systemd`
