+# Injective Chain Keyring Helper
+
+Creates a new keyring from a variety of options. See `ConfigOpt` and related options. This keyring helper allows initializing the Cosmos SDK keyring used for signing transactions.
+
+It allows flexibly defining a static configuration of keys, supports multiple pre-defined keys in the same keyring, and allows loading keys from a file, deriving from mnemonic, or reading plain private key bytes from a HEX string. Extremely useful for testing and local development, but also robust for production use cases.
+
+## Usage
+
+```go
+NewCosmosKeyring(cdc codec.Codec, opts ...ConfigOpt) (sdk.AccAddress, cosmkeyring.Keyring, error)
+```
+
+**ConfigOpts:**
+
+These options are global on the keyring level.
+
+* `WithKeyringDir` option sets keyring path in the filesystem, useful when keyring backend is `file`.
+* `WithKeyringAppName` option sets keyring application name (defaults to `injectived`)
+* `WithKeyringBackend` sets the keyring backend. Expected values: `test`, `file`, `os`.
+* `WithUseLedger` sets the option to use hardware wallet, if available on the system.
+
+These options allow adding keys to the keyring during initialization.
+
+* `WithKey` adds a single key to the keyring, without having alias name.
+* `WithNamedKey` addes a single key to the keyring, with a name.
+* `WithDefaultKey` sets a default key reference to use for signing (by name).
+
+**KeyConfigOpts:**
+
+These options are set per key.
+
+* `WithKeyFrom` sets the key name to use for signing. Must exist in the provided keyring.
+* `WithKeyPassphrase` sets the passphrase for keyring files. The package will fallback to `os.Stdin` if this option was not provided, but passphrase is required.
+* `WithPrivKeyHex` allows specifying a private key as plain-text hex. Insecure option, use for testing only. The package will create a virtual keyring holding that key, to meet all the interfaces.
+* `WithMnemonic` allows specifying a mnemonic phrase as plain-text hex. Insecure option, use for testing only. The package will create a virtual keyring to derive the keys and meet all the interfaces.
+
+## Examples
+
+Initialize an in-memory keyring with a private key hex:
+
+```go
+NewCosmosKeyring(
+    cdc,
+    WithKey(
+        WithPrivKeyHex("e6888cb164d52e4880e08a8a5dbe69cd62f67fde3d5906f2c5c951be553b2267"),
+        WithKeyFrom("sender"),
+    ),
+)
+```
+
+Initialize an in-memory keyring with a mnemonic phrase:
+
+```go
+NewCosmosKeyring(
+    s.cdc,
+    WithKey(
+        WithMnemonic("real simple naive ....... love"),
+        WithKeyFrom("sender"),
+    ),
+)
+```
+
+Real world use case of keyring initialization from CLI flags, with a single named key set as default:
+
+```go
+NewCosmosKeyring(
+    cdc,
+    WithKeyringDir(*keyringDir),
+    WithKeyringAppName(*keyringAppName),
+    WithKeyringBackend(Backend(*keyringBackend)),
+    WithNamedKey(
+        "dispatcher",
+        WithKeyFrom(*dispatcherKeyFrom),
+        WithKeyPassphrase(*dispatcherKeyPassphrase),
+        WithPrivKeyHex(*dispatcherKeyPrivateHex),
+        WithMnemonic(*dispatcherKeyMnemonic),
+    ),
+    WithDefaultKey(
+        "dispatcher",
+    ),
+)
+```
+
+## Testing
+
+```bash
+go test -v -cover
+
+PASS
+coverage: 83.1% of statements
+```
+
+## Generating a Test Fixture
+
+```bash
+> cd testdata
+
+> injectived keys --keyring-dir `pwd` --keyring-backend file add test
+```
+
+Passphrase should be `test12345678` for this fixture to work.
