+# Using lssi
+Any plugin can be modified by lssi by doing the following in the eatit-cfg.lua:
+```lua
+plugins = { -- the  plugins you want to load
+  { 'https://git.squi.bid/eat-it',
+    file = 'eatit.lua',
+    dir = 'scripts',
+    lssi = {
+        -- code                  line
+        { 'print("hello world")', 'G' },
+    }
+  },
+}
+```
+The line option can be 'g' for top of file, 'G' for bottom of file, or any 
+number in between.
