+# Using prebuilds
+
+Prebuilds are more convenient way of using monero_c in your code (although these builds should **NOT** be used in
+production). There are several ways in which you can use prebuilds
+
+## The monero_c way
+
+1. Go to https://github.com/MrCyjaneK/monero_c/releases
+2. Click on the release that you are interested in
+3. Download release-bundle.zip
+4. Unzip it in monero_c directory
+
+That zip file contains all builds that monero_c supports prepared in the exactly same way as you would prepare them if
+building on your own. This is the easiest way to get started.
+
+> Keep in mind that release-bundle.zip contains .xz files inside, so if you want to actually use them you need to use
+> them you need to unxz them first
+> ```bash
+> $ unxz -f -k release/*/*.xz
+> ```
+
+## The monero_c way (different)
+
+Alternatively you can go to releases tab and grab whatever you need, there are over 40 libraries. Surely one will fit 
+your use case.
+
+## The build_moneroc.sh way
+
+This method is used by [xmruw](https://github.com/mrcyjanek/unnamed_monero_wallet) and 
+[monero-tui](https://github.com/Im-Beast/monero-tui).
+
+It supports both building and downloading prebuilds and putting them in correct location, [have a look at the code 
+yourself](https://github.com/MrCyjaneK/unnamed_monero_wallet/blob/master-rewrite/build_moneroc.sh)
+
+```bash
+$ ./build_moneroc.sh
+    --prebuild # allow downloads of prebuilds
+    --coin # monero/wownero 
+    --tag v0.18.3.3-RC45 # which tag to build / download
+    --triplet x86_64-linux-android # which triplet to build / download
+    --location android/.../jniLibs/x86_64 # where to but the libraries
+```
+
+## The cake wallet way
+
+There is a simple script in cake_wallet written in `dart` that runs on all platform (including windows) which downloads
+all required libraries for selected platforms in one go. 
+[You can take look at it here](https://github.com/cake-tech/cake_wallet/blob/main/tool/download_moneroc_prebuilds.dart)
