 **FlatBuffers** is a cross platform serialization library architected for
 maximum memory efficiency. It allows you to directly access serialized data without parsing/unpacking it first, while still having great forwards/backwards compatibility.
 
+## Quick Start
+
+1. Build the compiler for flatbuffers (`flatc`)
+
+    Use `cmake` to create the build files for your platform and then perform the compilation (Linux example).
+
+    ```
+    cmake -G "Unix Makefiles"
+    make -j
+    ```
+
+2. Define your flatbuffer schema (`.fbs`)
+
+    Write the [schema](https://flatbuffers.dev/flatbuffers_guide_writing_schema.html) to define the data you want to serialize. See [monster.fbs](https://github.com/google/flatbuffers/blob/master/samples/monster.fbs) for an example.
+
+3. Generate code for your language(s)
+
+    Use the `flatc` compiler to take your schema and generate language-specific code:
+
+    ```
+    ./flatc --cpp --rust monster.fbs
+    ```
+    
+    Which generates `monster_generated.h` and `monster_generated.rs` files.
+
+4. Serialize data
+
+    Use the generated code, as well as the `FlatBufferBuilder` to construct your serialized buffer. ([`C++` example](https://github.com/google/flatbuffers/blob/master/samples/sample_binary.cpp#L24-L56))
+
+5. Transmit/store/save Buffer
+
+    Use your serialized buffer however you want. Send it to someone, save it for later, etc...
+
+6. Read the data
+
+    Use the generated accessors to read the data from the serialized buffer.
+    
+    It doesn't need to be the same language/schema version, FlatBuffers ensures the data is readable across languages and schema versions. See the [`Rust` example](https://github.com/google/flatbuffers/blob/master/samples/sample_binary.rs#L92-L106) reading the data written by `C++`.

-## Dart 2.0 notes
-Version 2.0.5 ships with it's own custom build of `flatc` because this is an extraordinary release to catch-up
-with FlatBuffers for other platforms. This generator can only generate dart code (to avoid generating code for other platforms which isn't released yet).
-On the other hand, the generated code still produces standard binary FlatBuffers compatible with other languages.
-In other words: only `flatc --dart ...` works with this generator, but your app will be able to produce and read standard binary (`Uint8List`) FlatBuffers that are fully compotible with other languages supporting FlatBuffers (e.g. Java, C++, ...).
-
-In the future a common `flatc` binary for all platforms would be shipped through GitHub release page instead.

+## Buffer verification
+
+As mentioned in [C++ Usage](@ref flatbuffers_guide_use_cpp) buffer
+accessor functions do not verify buffer offsets at run-time.
+If it is necessary, you can optionally use a buffer verifier before you
+access the data. This verifier will check all offsets, all sizes of
+fields, and null termination of strings to ensure that when a buffer
+is accessed, all reads will end up inside the buffer.
+
+Each root type will have a verification function generated for it,
+e.g. `Monster.VerifyMonster`. This can be called as shown:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cs}
+    var ok = Monster.VerifyMonster(buf);
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+if `ok` is true, the buffer is safe to read.
+
+For a more detailed control of verification `MonsterVerify.Verify`
+for `Monster` type can be used:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cs}
+    # Sequence of calls
+    FlatBuffers.Verifier verifier = new FlatBuffers.Verifier(buf);
+    var ok = verifier.VerifyBuffer("MONS", false, MonsterVerify.Verify);
+
+    # Or single line call
+    var ok = new FlatBuffers.Verifier(bb).setStringCheck(true).\
+             VerifyBuffer("MONS", false, MonsterVerify.Verify);
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+if `ok` is true, the buffer is safe to read.
+
+A second parameter of `verifyBuffer` specifies whether buffer content is
+size prefixed or not. In the example above, the buffer is assumed to not include
+size prefix (`false`).
+
+Verifier supports options that can be set using appropriate fluent methods:
+* SetMaxDepth - limit the nesting depth. Default: 1000000
+* SetMaxTables - total amount of tables the verifier may encounter. Default: 64
+* SetAlignmentCheck - check content alignment. Default: True
+* SetStringCheck - check if strings contain termination '0' character. Default: true
+
