+## Getting the bits
+
+### Releases
+
+[Download the latest build](https://github.com/LogCraftIO/logcraft-cli-plugins/releases) of the desired plugins directly from the releases page. This is the recommended approach for most users.
+
+### Building from the sources
+
+If you prefer, you can build the plugins from the sources:
+
+First, clone the repository:
+
+```bash
+git clone https://github.com/LogCraftIO/logcraft-cli-plugins
+cd logcraft-cli-plugins
+```
+
+Then, enter the directory of the plugin of your choice
+
+```bash
+cd <PLUGIN_DIR>
+cargo component build --release
+```
+
+For example
+```bash
+cd splunk
+cargo component build --release
+```
+
+The plugin will be released under: `../target/wasm32-wasi/release/` as a `.wasm` file. 
+
+Add it to `lgc` using the `plugins install` command:
+
+```bash
+~$ cd your-work-dir
+~$ lgc plugins install /path/to/target/wasm32-wasi/release/<PLUGIN>.wasm
+```
+For example:
+
+```bash
+~$ lgc plugins install /path/to/target/wasm32-wasi/release/splunk.wasm
+```
+
+Note that compiling the plugin requires `cargo-component` and `wasm32-wasi`:
+
+```bash
+cargo install cargo-component --locked
+rustup target add wasm32-wasi
+```
