 ### Translations in Lua controller code and Lua CBIs
-As hinted at in the Templates doc, the `%:` is actually invoking a `translate()` function.
+As hinted at in the Templates doc, the `%:` invokes a `translate()` function.
 In most controller contexts, this is already available for you, but if necessary, is available for include in `luci.i18n.translate`
 
 
 ## Translation files
 Translations are saved in the folder `po/` within each individual LuCI component directory, e.g. `applications/luci-app-acl/po/`.
-You find the reference in `po/templates/<package>.pot`.
+The template is in `po/templates/<package>.pot`.
 The actual translation files can be found at `po/[lang]/[package].po`.
 
 In order to use the commands below you need to have the `gettext` utilities (`msgcat`, `msgfmt`, `msgmerge`) installed on your system.
-On Debian/Ubuntu you can install with `sudo apt install gettext`.

 ### LMO files
 The `*.po` files are big so Luci needs them in a compact compiled [LMO format](./LMO.md).
-Luci reads `*.lmo` translations from `/usr/lib/lua/luci/i18n/` folder.
+Luci reads `*.lmo` translations from the `/usr/lib/lua/luci/i18n/` folder.
