 Example usage
 
-The example below shows assert used with some common types.
+All the assertions in this package use testing.T.Helper to mark themselves as
+test helpers. This allows the testing package to print the filename and line
+number of the file function that failed.
 
+	assert.NilError(t, err)
+	// filename_test.go:212: assertion failed: error is not nil: file not found
 
-	import (

+from the helper function so that the filename and line number remain correct.
 
-	    "gotest.tools/assert"
-	    is "gotest.tools/assert/cmp"
-	)
+The examples below show assert used with some common types and the failure
+messages it produces. The filename and line number portion of the failure
+message is omitted from these examples for brevity.

-	    // booleans
-	    assert.Assert(t, ok)

+
+Assert and Check
+
+Assert and Check are very similar, they both accept a Comparison, and fail
+the test when the comparison fails. The one difference is that Assert uses
+testing.T.FailNow to fail the test, which will end the test execution immediately.
+Check uses testing.T.Fail to fail the test, which allows it to return the
+result of the comparison, then proceed with the rest of the test case.
+
+Like testing.T.FailNow, Assert must be called from the goroutine running the test,
+not from other goroutines created during the test. Check is safe to use from any
+goroutine.
