-## Hugo tags generator
+## Hugo help tags generator
+
+### Usage
+
+1. Install dependency: https://mikefarah.gitbook.io/yq/
+2. Clone hugo docs and checkout to your hugo version
+
+```bash
+git clone https://github.com/gohugoio/hugoDocs/
+git checkout v0.147.5
+```
+3. Generate tags
+
+```bash
+cd /path/to/your/hugo/website
+hugotags.sh /path/to/cloneOf/hugoDocs/content/en >  tags
+```
+
+### vim
+
+All tag commands and mapping works good. The one I use often are below
+* `Ctrl w Ctrl ]`   => Open the tag in horizontal split
+* `Ctrl w g Ctrl ]` => Same as above but if there are more than one tag, shows
+  a list instead going to the first one
