+# V8 Build Tools
+
+This repository contains all the necessary tools and scripts to build Google's V8 for embedding.
+
+## Prerequisites
+
+1. **Clone this repository:**
+
+    ```sh
+    git clone https://github.com/citizenfx/v8-build.git
+    cd v8-build
+    ```
+
+2. **Python 3.8+ must be installed on your system.**
+
+3. **Drive Mapping:**
+
+    Ensure you do not have a drive mapped to the letter 'Y'. If you do, change the mapping drive target to another letter in the `prepare-depot.ps1` and `build.ps1` files.
+
+## Building V8
+
+1. **Prepare the depot:**
+
+    Run the following script to prepare the depot:
+
+    ```sh
+    .\build\prepare-depot.ps1
+    ```
+
+2. **Build V8:**
+
+    Run the build script:
+
+    ```sh
+    .\build\build.ps1
+    ```
+
+3. **Wait approximately 20 minutes** for the build process to complete.
+
+## Build Results
+
+The build results will be located in the `builds_results` folder.

+# In case if update needed
+## Things you need to know
+* There was bug in ICU script that generating ASM file with icudata for embedding. If it still generates ASM file with `icudata` variable that prefixed with `_` - bug still exists and clang compilation will fail. We are doing trick to remove underscore in build script
+* By default v8_monolith use static crt, so are forcing it to use dynamic CRT. Maybe with some time Google will fix it, so then you need to check flags with `gn args` and look for flag that forcing dynamic crt to be used.
+
+## How to update to newer V8
+Simply put new commit hash/tag/branch from [V8 repository](https://github.com/v8/v8) into `target.txt`. It will be added to `git checkout` command
