+
+This is a library implementing parts of the [Matrix](https://matrix.org/) [Client-Server API](https://spec.matrix.org/v1.8/client-server-api/).
+It is written in C and supports sending and receiving of messages, including end-to-end encryption.
+Device verification is also supported.
+
+## Building
+
+Building requires a C/C++ compiler and make.
+To build the dependencies run `make deps`.
+To build any of the examples run `make out/examples/<example>`.
+To use the library:
+- Add `src/matrix.c` to compilation
+- Add either `src/matrix_http_mongoose.c` or `src/matrix_http_esp32.c` to compilation
+- Add `out/*.o` to compilation
+- Add include path `src/`
+- Add include path `ext/olm/include/`
+- Add include path `ext/mjson/src/`
+- Add include path `ext/mongoose/`
+
+## Dependencies
+[Mongoose](https://github.com/cesanta/mongoose)
+[mjson](https://github.com/cesanta/mjson)
+[Olm](https://gitlab.matrix.org/matrix-org/olm)
+
+## Examples
+
+### Sending an encrypted message
+```
+MatrixMegolmOutSession * megolmOutSession;
+MatrixClientNewMegolmOutSession(&client,
+ ROOM_ID,
+ &megolmOutSession);
+printf("megolm session id: %.10s... key: %.10s...\n", megolmOutSession->id, megolmOutSession->key);
+
+MatrixClientShareMegolmOutSession(&client,
+ USER_ID,
+ "ULZZOKJBYN",
+ megolmOutSession);
+
+MatrixClientSendEventEncrypted(&client,
+ ROOM_ID,
+ "m.room.message",
+ "{\"body\":\"Hello\",\"msgtype\":\"m.text\"}");
+```
+
+### Verification
+```
+// Request an encrypted event to enable verification
+STATIC char eventBuffer[1024];
+MatrixClientGetRoomEvent(client,
+ ROOM_ID,
+ EVENT_ID,
+ eventBuffer, 1024);
+
+#define SYNC_BUFFER_SIZE 1024*10
+STATIC char syncBuffer[SYNC_BUFFER_SIZE];
+STATIC char nextBatch[1024];
+
+while (! client->verified) {
+ MatrixClientSync(client, syncBuffer, SYNC_BUFFER_SIZE, nextBatch, 1024);
+}
+```
