+# Assert Go
+
+A lightweight assertion library for Go, designed for systems and real-time programming with structured logging and flush controls.
+
+## Installation
+
+```bash
+go get github.com/ZanzyTHEbar/assert-lib
+```
+
+## Usage
+
+```go
+package main
+
+import (
+    "context"
+    "github.com/ZanzyTHEbar/assert-lib/assert"
+)
+
+func main() {
+    handler := assert.NewAssertHandler()
+    
+    handler.Assert(context.TODO(), false, "This should fail")
+}
+```
+
+Check out the [examples](/examples/) directory for usage examples.
+
+## Features
+
+- **Assertions**: Assert, Nil, NotNil, NoError, Never.
+- **Flush Management**: Control output flushes with AssertFlush.
+- **Context-Based Logging**: Attach structured logging to your assertion calls.
+- **Custom Loggers**: Use your own logger with the AssertHandler interface.
+
+## Examples
+
+```bash
+go run examples/basic_assertion.go
+go run examples/deferred_assertions.go
+go run examples/custom_exit.go
+go run examples/formater.go
+```
