 There are some steps to do so below.
 Make sure to complete them as the gitea user in ~:
 
-* Stop Gogs
-* cd ~
-* wget https://github.com/go-gitea/gitea/archive/v1.0.0.zip
-* unzip v1.0.0.zip
-* cp -r gogs gitea
-* If you have custom content migrated from gogs/custom/ folder, like templates or localization files, you should manually merge these because these files changed on Gitea.
-* cp -r gitea-v1.0.0/options gitea/options
-* cp -r gogs-repositories/ gitea-repositories
-* cp -r gogs-data/ gitea-data/
-* vim gitea/custom/conf/app.ini
-
-Change gogs specific information:
+* Download the file matching your platform from the [downloads page](https://dl.gitea.io/gitea)
+* Put the binary at the desired install location
+* Copy `gogs/custom/conf/app.ini` to `gitea/custom/conf/app.ini`
+* If you have custom content folders in `gogs/custom/` copy them to `gitea/custom/options`. This is used to override gitignores, labels, licenses, locales and readmes.
+  [Due to a bug](https://github.com/go-gitea/gitea/issues/529) custom templates aren't working at the moment.
+* Copy `gogs/data/` to `gitea/data/`. It contains issue attachments and avatars.
+* Verify by starting Gitea with `gitea web`
+* Enter Gitea admin panel on the UI, run `Rewrite '.ssh/authorized_keys' file` (caution: non-Gitea keys will be lost) and `Rewrite all update hook of repositories` (needed when custom config path is changed).
+  
+  
+### Change gogs specific information:
+
+* Rename `gogs-repositories/` to `gitea-repositories/`
