+## Linking backtraces to custom repositories
+
+Errbit builds backtraces with clickable links to Github and Bitbucket repositories.
+The entry 'custom backtrace URL template' can be used to support clickable backtraces with other repositories.
+
+The following fields are available for this template:
+
+- %{branch}: The repo branch name
+- %{file}: The relative file/path name of the backtrace file
+- %{line}: The line number the backtrace occurred
+- %{ebranch}: The URI escaped version of the branch name
+- %{efile}: The URI escaped version of the file name
+
+A few examples:
+
+- Gitea: `https://errbit.example.com/repo/name/src/branch/%{branch}/%{file}#L%{line}`
+- Gitlab: `https://errbit.example.com/repo/name/-/blob/%{branch}/%{file}#L%{line}`
