 # mt-matrix
 
-Matrix-Minetest bridge
+This repository serves as a bridge between Matrix and Minetest servers.
+
+## Setup
+
+1. Clone this repository into your Minetest mods folder:
+
+```sh
+git clone --recursive https://git.noordstar.me/Bram/mt-matrix.git
+```
+
+2. To access the Matrix homeserver, this mod needs access to HTTP calls. Add this mod to your `minetest.conf` settings at the field `secure.http_mods`:
+
+```
+#    Comma-separated list of mods that are allowed to access HTTP APIs, which
+#    allow them to upload and download data to/from the internet.
+#    type: string
+secure.http_mods=mt_matrix
+```
+
+3. Fill in the values in `config.lua`:
+
+```lua
+config = {
+
+    -- The user one expects to log in as
+    user = "@minetest:matrix.directory",
+
+    -- The URL where the user communicates with the Matrix homeserver
+    url = "https://synapse.matrix.directory",
+
+    -- Room ID that the Minetest server bridges to
+    room_id = "!fePhSRwZXgzmREGqFV:matrix.directory",
+
+    -- Access token to access the Matrix homeserver
+    access_token = "syt_bWluZXRlc3Q_TafRsEjsCwVaCxFYCIkT_2iChoq",
+
+    -- Average timeout duration
+    sync_timeout = 30
+}
+```
+
+4. Add the mod to your world configuration.
+
+Now you're good to go! Feel free to create issues or send me a message.
