+# ProxySwitcher
+
+ProxySwitcher is a Golang-based Windows application that allows you to easily switch
+internet proxy settings for various programs including the system settings. The
+application provides a command-line interface (CLI) through the usage of a library
+called [cobra](https://github.com/spf13/cobra). This CLI then provides commands to
+set, unset, and save proxy configurations, as well as a system tray icon for quick
+access to settings and toggling proxies.
+
+## Features
+
+- Switch internet proxy settings for various applications and the system.
+- Manage configurations through a `configs.json` file.
+- Command-line interface with commands like `set`, `unset`, and `save`.
+- System tray icon with options to enable and disable proxies, open settings,
+save configurations, or exit the application.
+
+## Installation
+
+1. Clone the repository:
+
+    ```powersell
+    git clone https://github.com/Baipyrus/ProxySwitcher.git
+    ```
+
+2. Build the project:
+
+    ```powersell
+    cd ProxySwitcher
+    go build
+    ```
+
+## Usage
+
+### CLI Commands
+
+- **set**: Enable all saved proxies including system proxy.
+
+    ```powersell
+    .\ProxySwitcher.exe set
+    ```
+

+    .\ProxySwitcher.exe save
+    ```
+
+### Configuration
+
+The programs for which the proxy settings should be managed are stored in a `configs.json`
+file, which can be modified directly or through the `save` command. For examples,
+please take a look at the [default config](./configs.json) or at the following block:
+
+```JSON
+[
+    {
+        "name": "test1", // Default CMD Name
+        "cmd": "echo 'Hello, World!'", // Optional
+        "set": [
+            {
+                "args": [
+                    "http"
+                ], // Optionally empty
+                "type": "text" // Default; Optional
+                "equator": " " // Default; Optional
+            }, // Writes "echo 'Hello, World!' http ", followed
+               // by your system proxy, to a powershell process.
+            {
+                "args": [
+                    "https"
+                ], // Optionally empty
+                "equator": "=" // Optional
+            }  // Writes "echo 'Hello, World!' https=", followed
+               // by your system proxy, to a powershell process.
+        ], // Optional
+        "unset": []
+        // "unset" has the contents as "set" above
+        // and it is also optional.
+    }, {
+        "name": "test2", // Default CMD Name
+        "cmd": "echo '$PRSW_ARG $PRSW_ARG'", // Optional
+        "set": [
+            {
+                "args": [
+                    "https"
+                ], // Optionally empty
+                "type": "variable" // Optional
+            }  // Writes "echo 'https <Your System Proxy>'"
+               // to a powershell process.
