+# Plugins
+
+Since 0.4.11 go-ipfs has an experimental plugin system for various added
+functionality.
+
+When IPFS node is created, it will load plugins from `$IPFS_PATH/plugins`
+directory (by default `~/.ipfs/plugins`).
+
+### Plugin types
+
+#### IPLD
+IPLD plugins add support for additional formats to `ipfs dag` and other IPLD
+related commands.
+
+### Supported plugins
+
+| Name | Type |
+|------|------|
+|  git | IPLD |
+
+#### Installation
+
+##### Linux
+
+1. Build included plugins:
+```bash
+go-ipfs$ make build_plugins
+go-ipfs$ ls plugin/plugins/*.so
+```
+
+3. Copy desired plugins to `$IPFS_PATH/plugins`
+```bash
+go-ipfs$ mkdir -p ~/.ipfs/plugins/
+go-ipfs$ cp plugin/plugins/git.so ~/.ipfs/plugins/
+```
+
+4. Restart daemon if it is running
+
+##### Other
+
+Go currently only supports plugins on Linux, for other platforms you will need
+to compile them into IPFS binary.
+
+1. Uncomment plugin entries in `plugin/loader/preload_list`
+2. Build ipfs
+```bash
+go-ipfs$ make build
+```
