+*This bot lets you use public transport in Berlin more easily.* You can do this:
+\`/a(bfahrt)\` – Show departures at a station.
+\`/r(oute)\` – Get routes from A to B.
+\`/n(earby)\` – Show stations around.
+When specifying time, you can use the following formats:
+- \`now\`
+- \`in 10min\`
+- \`tomorrow 17:20\`
+- \`8 pm\`
+- \`tuesday at 6\`
+The data behind this bot is from VBB, so departures & routing will be just as (in)accurate as in the BVG & VBB apps.`
