 Tink provides secure APIs that are easy to use correctly and hard(er) to misuse.

 To get a quick overview of Tink design please take a look at
 [slides](docs/Tink-a_cryptographic_library--RealWorldCrypto2019.pdf) from [a
 talk about Tink](https://www.youtube.com/watch?v=pqev9r3rUJs&t=9665) presented
 at [Real World Crypto 2019](https://rwc.iacr.org/2019/).
 
-## Getting started
-
-Tink primarily uses [Bazel](https://bazel.build) to manage building and testing
-the project.
-
-The recommended way to get started with Tink is to use
-[Bazelisk](https://github.com/bazelbuild/bazelisk). This tool is developed by
-the Bazel team and makes it easy to ensure usage of a version of Bazel that's
-compatible with the project.
-
-As a starting point, the
-[`examples`](https://github.com/google/tink/tree/master/examples) demonstrate
-performing simple tasks using Tink in a variety of languages.
-
-## Overview
-
-Tink performs cryptographic tasks via so-called [primitives](docs/PRIMITIVES.md),
-each of which is defined via a corresponding interface that specifies the
-functionality of the primitive. For example, _symmetric key encryption_ is
-offered via an [_AEAD-primitive_ (Authenticated Encryption with Associated
-Data)](docs/PRIMITIVES.md#authenticated-encryption-with-associated-data), that
-supports two operations:
-
-*   `encrypt(plaintext, associated_data)`, which encrypts the given `plaintext`
-    (using `associated_data` as additional AEAD-input) and returns the resulting
-    ciphertext
-*   `decrypt(ciphertext, associated_data)`, which decrypts the given
-    `ciphertext` (using `associated_data` as additional AEAD-input) and returns
-    the resulting plaintext
-
-Before implementations of primitives can be used, they must be registered at
-runtime with Tink, so that Tink "knows" the desired implementations. Here's how
-you can register all implementations of all primitives in Tink:
-
-```java
-    import com.google.crypto.tink.config.TinkConfig;
-
-    TinkConfig.register();
-```
-
-After implementations of primitives have been registered, the basic use of Tink
-proceeds in three steps:
-
-1.  Load or generate the cryptographic key material (a `Keyset` in Tink terms).
-2.  Use the key material to get an instance of the chosen primitive.
-3.  Use that primitive to accomplish the cryptographic task.
-
-Here is how these steps would look like when encrypting or decrypting with an
-AEAD primitive in Java:
-
-```java
-    import com.google.crypto.tink.Aead;
-    import com.google.crypto.tink.KeysetHandle;
-    import com.google.crypto.tink.aead.AeadKeyTemplates;
-
-    // 1. Generate the key material.
-    KeysetHandle keysetHandle = KeysetHandle.generateNew(
-        AeadKeyTemplates.AES128_GCM);
-
-    // 2. Get the primitive.
-    Aead aead = keysetHandle.getPrimitive(Aead.class);
-
-    // 3. Use the primitive.
-    byte[] ciphertext = aead.encrypt(plaintext, associatedData);
-```
-
