-Convert between binary and Base64 encoded string.
-Easily convert sensor raw values, structures, etc.
-
-# Example
-## Encode
-```c++
-const uint8_t data[] = {0x17, 0x77, 0x3B, 0x11, 0x82, 0xA4, 0xC4, 0xC8, 0x27, 0xBC, 0xED, 0x27, 0x07, 0xC1, 0x56, 0x57};
-auto dataLength = sizeof(data);
-char result[base64::encodeLength(dataLength)];
-
-base64::encode(data, dataLength, result);
-```
-
-## Decode
-```c++
-const char data[] = "F3c7EYKkxMgnvO0nB8FWVw==";
-uint8_t result[base64::decodeLength(data)];
-
-base64::decode(data, result);
-```

 # Details
-The only export of this library will be [`arduino_base64.hpp`](./src/arduino_base64.hpp).
-Other source files are for internal use and should not normally be include.
-
-This is library made to convert binary data (e.g. raw sensor values) to Base64 encoded string.
-String can be convert by cast them to byte arrays, but that's not what this library is for, nor do we plan to provide a means.
-If you want to convert string, use this library and implement the wrapper functions yourself.
+This library made to convert binary data (e.g. raw sensor values) to base64 encoded string.
+String can be convert by cast them to `uint8_t*`, but that not what this library is for, nor do we plan to provide means.

 # API
-## `base64::encode(input, inputLength, output)`
-- Arguments
-    - `input` : `const uint8_t*` ... Binary data.
-    - `inputLength` : `size_t` ... Number of input bytes.
-    - `output` : `char*` ... Base64 encoded string.
-- Result
-    - `void`
-
-If the input is string, cast it to `uint8_t*`.
-
-## `base64::encodeLength(inputLength)`
-- Arguments
-    - `inputLength` : `size_t` ... Number of input bytes.
-- Result
-    - `size_t` ... Number of output characters.
-
-## `base64::decode(input, output)`
-- Arguments
-    - `input` : `const char*` ... Base64 encoded string.
-    - `output` : `uint8_t*` ... Binary data.
-- Result
-    - `void`
-
-If the output is string, cast it to `char*`.
-
-## `base64::decodeLength(input)`
-- Arguments
-    - `input` : `const char*` ... Base64 encoded string.
-- Result
-    - `size_t` ... Number of output bytes.
+See [`arduino_base64.hpp`](./src/arduino_base64.hpp) for details.
